Introduction

Laravel provides a very fluent API for making HTTP requests to your application and examining the responses. For example, take a look at the feature test defined below:

<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function test_a_basic_request()
    {
        $response = $this->get('/');
        $response->assertStatus(200);
    }
}

The get method makes a GET request into the application, while the assertStatus method asserts that the returned response should have the given HTTP status code. In addition to this simple assertion, Laravel also contains a variety of assertions for inspecting the response headers, content, JSON structure, and more.

Making Requests

To make a request to your application, you may invoke the get, post, put, patch, or delete methods within your test. These methods do not actually issue a "real" HTTP request to your application. Instead, the entire network request is simulated internally.

Instead of returning an Illuminate\Http\Response instance, test request methods return an instance of Illuminate\Testing\TestResponse, which provides a variety of helpful assertions that allow you to inspect your application's responses:

<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function test_a_basic_request()
    {
        $response = $this->get('/');
        $response->assertStatus(200);
    }
}

In general, each of your tests should only make one request to your application. Unexpected behavior may occur if multiple requests are executed within a single test method.

Note
For convenience, the CSRF middleware is automatically disabled when running tests.

Customizing Request Headers

You may use the withHeaders method to customize the request's headers before it is sent to the application. This method allows you to add any custom headers you would like to the request:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function test_interacting_with_headers()
    {
        $response = $this->withHeaders([
            'X-Header' => 'Value',
        ])->post('/user', ['name' => 'Sally']);
        $response->assertStatus(201);
    }
}

Cookies

You may use the withCookie or withCookies methods to set cookie values before making a request. The withCookie method accepts a cookie name and value as its two arguments, while the withCookies method accepts an array of name / value pairs:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    public function test_interacting_with_cookies()
    {
        $response = $this->withCookie('color', 'blue')->get('/');
        $response = $this->withCookies([
            'color' => 'blue',
            'name' => 'Taylor',
        ])->get('/');
    }
}

Session / Authentication

Laravel provides several helpers for interacting with the session during HTTP testing. First, you may set the session data to a given array using the withSession method. This is useful for loading the session with data before issuing a request to your application:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    public function test_interacting_with_the_session()
    {
        $response = $this->withSession(['banned' => false])->get('/');
    }
}

Laravel's session is typically used to maintain state for the currently authenticated user. Therefore, the actingAs helper method provides a simple way to authenticate a given user as the current user. For example, we may use a model factory to generate and authenticate a user:

<?php
namespace Tests\Feature;
use App\Models\User;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    public function test_an_action_that_requires_authentication()
    {
        $user = User::factory()->create();
        $response = $this->actingAs($user)
                         ->withSession(['banned' => false])
                         ->get('/');
    }
}

You may also specify which guard should be used to authenticate the given user by passing the guard name as the second argument to the actingAs method. The guard that is provided to the actingAs method will also become the default guard for the duration of the test:

$this->actingAs($user, 'web')

Debugging Responses

After making a test request to your application, the dump, dumpHeaders, and dumpSession methods may be used to examine and debug the response contents:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function test_basic_test()
    {
        $response = $this->get('/');
        $response->dumpHeaders();
        $response->dumpSession();
        $response->dump();
    }
}

Alternatively, you may use the dd, ddHeaders, and ddSession methods to dump information about the response and then stop execution:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function test_basic_test()
    {
        $response = $this->get('/');
        $response->ddHeaders();
        $response->ddSession();
        $response->dd();
    }
}

Exception Handling

Sometimes you may want to test that your application is throwing a specific exception. To ensure that the exception does not get caught by Laravel's exception handler and returned as an HTTP response, you may invoke the withoutExceptionHandling method before making your request:

$response = $this->withoutExceptionHandling()->get('/');

In addition, if you would like to ensure that your application is not utilizing features that have been deprecated by the PHP language or the libraries your application is using, you may invoke the withoutDeprecationHandling method before making your request. When deprecation handling is disabled, deprecation warnings will be converted to exceptions, thus causing your test to fail:

$response = $this->withoutDeprecationHandling()->get('/');

Testing JSON APIs

Laravel also provides several helpers for testing JSON APIs and their responses. For example, the json, getJson, postJson, putJson, patchJson, deleteJson, and optionsJson methods may be used to issue JSON requests with various HTTP verbs. You may also easily pass data and headers to these methods. To get started, let's write a test to make a POST request to /api/user and assert that the expected JSON data was returned:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function test_making_an_api_request()
    {
        $response = $this->postJson('/api/user', ['name' => 'Sally']);
        $response
            ->assertStatus(201)
            ->assertJson([
                'created' => true,
            ]);
    }
}

In addition, JSON response data may be accessed as array variables on the response, making it convenient for you to inspect the individual values returned within a JSON response:

$this->assertTrue($response['created']);

Note
The assertJson method converts the response to an array and utilizes PHPUnit::assertArraySubset to verify that the given array exists within the JSON response returned by the application. So, if there are other properties in the JSON response, this test will still pass as long as the given fragment is present.

Asserting Exact JSON Matches

As previously mentioned, the assertJson method may be used to assert that a fragment of JSON exists within the JSON response. If you would like to verify that a given array exactly matches the JSON returned by your application, you should use the assertExactJson method:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function test_asserting_an_exact_json_match()
    {
        $response = $this->postJson('/user', ['name' => 'Sally']);
        $response
            ->assertStatus(201)
            ->assertExactJson([
                'created' => true,
            ]);
    }
}

Asserting On JSON Paths

If you would like to verify that the JSON response contains the given data at a specified path, you should use the assertJsonPath method:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function test_asserting_a_json_paths_value()
    {
        $response = $this->postJson('/user', ['name' => 'Sally']);
        $response
            ->assertStatus(201)
            ->assertJsonPath('team.owner.name', 'Darian');
    }
}

The assertJsonPath method also accepts a closure, which may be used to dynamically determine if the assertion should pass:

$response->assertJsonPath('team.owner.name', fn ($name) => strlen($name) >= 3);

Fluent JSON Testing

Laravel also offers a beautiful way to fluently test your application's JSON responses. To get started, pass a closure to the assertJson method. This closure will be invoked with an instance of Illuminate\Testing\Fluent\AssertableJson which can be used to make assertions against the JSON that was returned by your application. The where method may be used to make assertions against a particular attribute of the JSON, while the missing method may be used to assert that a particular attribute is missing from the JSON:

use Illuminate\Testing\Fluent\AssertableJson;
/**
 * A basic functional test example.
 *
 * @return void
 */
public function test_fluent_json()
{
    $response = $this->getJson('/users/1');
    $response
        ->assertJson(fn (AssertableJson $json) =>
            $json->where('id', 1)
                 ->where('name', 'Victoria Faith')
                 ->where('email', fn ($email) => str($email)->is('victoria@gmail.com'))
                 ->whereNot('status', 'pending')
                 ->missing('password')
                 ->etc()
        );
}

Understanding The etc Method

In the example above, you may have noticed we invoked the etc method at the end of our assertion chain. This method informs Laravel that there may be other attributes present on the JSON object. If the etc method is not used, the test will fail if other attributes that you did not make assertions against exist on the JSON object.

The intention behind this behavior is to protect you from unintentionally exposing sensitive information in your JSON responses by forcing you to either explicitly make an assertion against the attribute or explicitly allow additional attributes via the etc method.

However, you should be aware that not including the etc method in your assertion chain does not ensure that additional attributes are not being added to arrays that are nested within your JSON object. The etc method only ensures that no additional attributes exist at the nesting level in which the etc method is invoked.

Asserting Attribute Presence / Absence

To assert that an attribute is present or absent, you may use the has and missing methods:

$response->assertJson(fn (AssertableJson $json) =>
    $json->has('data')
         ->missing('message')
);

In addition, the hasAll and missingAll methods allow asserting the presence or absence of multiple attributes simultaneously:

$response->assertJson(fn (AssertableJson $json) =>
    $json->hasAll(['status', 'data'])
         ->missingAll(['message', 'code'])
);

You may use the hasAny method to determine if at least one of a given list of attributes is present:

$response->assertJson(fn (AssertableJson $json) =>
    $json->has('status')
         ->hasAny('data', 'message', 'code')
);

Asserting Against JSON Collections

Often, your route will return a JSON response that contains multiple items, such as multiple users:

Route::get('/users', function () {
    return User::all();
});

In these situations, we may use the fluent JSON object's has method to make assertions against the users included in the response. For example, let's assert that the JSON response contains three users. Next, we'll make some assertions about the first user in the collection using the first method. The first method accepts a closure which receives another assertable JSON string that we can use to make assertions about the first object in the JSON collection:

$response
    ->assertJson(fn (AssertableJson $json) =>
        $json->has(3)
             ->first(fn ($json) =>
                $json->where('id', 1)
                     ->where('name', 'Victoria Faith')
                     ->where('email', fn ($email) => str($email)->is('victoria@gmail.com'))
                     ->missing('password')
                     ->etc()
             )
    );

Scoping JSON Collection Assertions

Sometimes, your application's routes will return JSON collections that are assigned named keys:

Route::get('/users', function () {
    return [
        'meta' => [...],
        'users' => User::all(),
    ];
})

When testing these routes, you may use the has method to assert against the number of items in the collection. In addition, you may use the has method to scope a chain of assertions:

$response
    ->assertJson(fn (AssertableJson $json) =>
        $json->has('meta')
             ->has('users', 3)
             ->has('users.0', fn ($json) =>
                $json->where('id', 1)
                     ->where('name', 'Victoria Faith')
                     ->where('email', fn ($email) => str($email)->is('victoria@gmail.com'))
                     ->missing('password')
                     ->etc()
             )
    );

However, instead of making two separate calls to the has method to assert against the users collection, you may make a single call which provides a closure as its third parameter. When doing so, the closure will automatically be invoked and scoped to the first item in the collection:

$response
    ->assertJson(fn (AssertableJson $json) =>
        $json->has('meta')
             ->has('users', 3, fn ($json) =>
                $json->where('id', 1)
                     ->where('name', 'Victoria Faith')
                     ->where('email', fn ($email) => str($email)->is('victoria@gmail.com'))
                     ->missing('password')
                     ->etc()
             )
    );

Asserting JSON Types

You may only want to assert that the properties in the JSON response are of a certain type. The Illuminate\Testing\Fluent\AssertableJson class provides the whereType and whereAllType methods for doing just that:

$response->assertJson(fn (AssertableJson $json) =>
    $json->whereType('id', 'integer')
         ->whereAllType([
            'users.0.name' => 'string',
            'meta' => 'array'
        ])
);

You may specify multiple types using the | character, or passing an array of types as the second parameter to the whereType method. The assertion will be successful if the response value is any of the listed types:

$response->assertJson(fn (AssertableJson $json) =>
    $json->whereType('name', 'string|null')
         ->whereType('id', ['string', 'integer'])
);

The whereType and whereAllType methods recognize the following types: string, integer, double, boolean, array, and null.

Testing File Uploads

The Illuminate\Http\UploadedFile class provides a fake method which may be used to generate dummy files or images for testing. This, combined with the Storage facade's fake method, greatly simplifies the testing of file uploads. For example, you may combine these two features to easily test an avatar upload form:

<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    public function test_avatars_can_be_uploaded()
    {
        Storage::fake('avatars');
        $file = UploadedFile::fake()->image('avatar.jpg');
        $response = $this->post('/avatar', [
            'avatar' => $file,
        ]);
        Storage::disk('avatars')->assertExists($file->hashName());
    }
}

If you would like to assert that a given file does not exist, you may use the assertMissing method provided by the Storage facade:

Storage::fake('avatars');
// ...
Storage::disk('avatars')->assertMissing('missing.jpg');

Fake File Customization

When creating files using the fake method provided by the UploadedFile class, you may specify the width, height, and size of the image (in kilobytes) in order to better test your application's validation rules:

UploadedFile::fake()->image('avatar.jpg', $width, $height)->size(100);

In addition to creating images, you may create files of any other type using the create method:

UploadedFile::fake()->create('document.pdf', $sizeInKilobytes);

If needed, you may pass a $mimeType argument to the method to explicitly define the MIME type that should be returned by the file:

UploadedFile::fake()->create(
    'document.pdf', $sizeInKilobytes, 'application/pdf'
);

Testing Views

Laravel also allows you to render a view without making a simulated HTTP request to the application. To accomplish this, you may call the view method within your test. The view method accepts the view name and an optional array of data. The method returns an instance of Illuminate\Testing\TestView, which offers several methods to conveniently make assertions about the view's contents:

<?php
namespace Tests\Feature;
use Tests\TestCase;
class ExampleTest extends TestCase
{
    public function test_a_welcome_view_can_be_rendered()
    {
        $view = $this->view('welcome', ['name' => 'Taylor']);
        $view->assertSee('Taylor');
    }
}

The TestView class provides the following assertion methods: assertSee, assertSeeInOrder, assertSeeText, assertSeeTextInOrder, assertDontSee, and assertDontSeeText.

If needed, you may get the raw, rendered view contents by casting the TestView instance to a string:

$contents = (string) $this->view('welcome');

Sharing Errors

Some views may depend on errors shared in the global error bag provided by Laravel. To hydrate the error bag with error messages, you may use the withViewErrors method:

$view = $this->withViewErrors([
    'name' => ['Please provide a valid name.']
])->view('form');
$view->assertSee('Please provide a valid name.');

Rendering Blade & Components

If necessary, you may use the blade method to evaluate and render a raw Blade string. Like the view method, the blade method returns an instance of Illuminate\Testing\TestView:

$view = $this->blade(
    '<x-component :name="$name" />',
    ['name' => 'Taylor']
);
$view->assertSee('Taylor');

You may use the component method to evaluate and render a Blade component. The component method returns an instance of Illuminate\Testing\TestComponent:

$view = $this->component(Profile::class, ['name' => 'Taylor']);
$view->assertSee('Taylor');

Available Assertions

Response Assertions

Laravel's Illuminate\Testing\TestResponse class provides a variety of custom assertion methods that you may utilize when testing your application. These assertions may be accessed on the response that is returned by the json, get, post, put, and delete test methods:

assertCookie

Assert that the response contains the given cookie:

$response->assertCookie($cookieName, $value = null);

assertCookieExpired

Assert that the response contains the given cookie and it is expired:

$response->assertCookieExpired($cookieName);

assertCookieNotExpired

Assert that the response contains the given cookie and it is not expired:

$response->assertCookieNotExpired($cookieName);

assertCookieMissing

Assert that the response does not contain the given cookie:

$response->assertCookieMissing($cookieName);

assertCreated

Assert that the response has a 201 HTTP status code:

$response->assertCreated();

assertDontSee

Assert that the given string is not contained within the response returned by the application. This assertion will automatically escape the given string unless you pass a second argument of false:

$response->assertDontSee($value, $escaped = true);

assertDontSeeText

Assert that the given string is not contained within the response text. This assertion will automatically escape the given string unless you pass a second argument of false. This method will pass the response content to the strip_tags PHP function before making the assertion:

$response->assertDontSeeText($value, $escaped = true);

assertDownload

Assert that the response is a "download". Typically, this means the invoked route that returned the response returned a Response::download response, BinaryFileResponse, or Storage::download response:

$response->assertDownload();

If you wish, you may assert that the downloadable file was assigned a given file name:

$response->assertDownload('image.jpg');

assertExactJson

Assert that the response contains an exact match of the given JSON data:

$response->assertExactJson(array $data);

assertForbidden

Assert that the response has a forbidden (403) HTTP status code:

$response->assertForbidden();

assertHeader

Assert that the given header and value is present on the response:

$response->assertHeader($headerName, $value = null);

assertHeaderMissing

Assert that the given header is not present on the response:

$response->assertHeaderMissing($headerName);

assertJson

Assert that the response contains the given JSON data:

$response->assertJson(array $data, $strict = false);

The assertJson method converts the response to an array and utilizes PHPUnit::assertArraySubset to verify that the given array exists within the JSON response returned by the application. So, if there are other properties in the JSON response, this test will still pass as long as the given fragment is present.

assertJsonCount

Assert that the response JSON has an array with the expected number of items at the given key:

$response->assertJsonCount($count, $key = null);

assertJsonFragment

Assert that the response contains the given JSON data anywhere in the response:

Route::get('/users', function () {
    return [
        'users' => [
            [
                'name' => 'Taylor Otwell',
            ],
        ],
    ];
});
$response->assertJsonFragment(['name' => 'Taylor Otwell']);

assertJsonMissing

Assert that the response does not contain the given JSON data:

$response->assertJsonMissing(array $data);

assertJsonMissingExact

Assert that the response does not contain the exact JSON data:

$response->assertJsonMissingExact(array $data);

assertJsonMissingValidationErrors

Assert that the response has no JSON validation errors for the given keys:

$response->assertJsonMissingValidationErrors($keys);

Note
The more generic assertValid method may be used to assert that a response does not have validation errors that were returned as JSON and that no errors were flashed to session storage.

assertJsonPath

Assert that the response contains the given data at the specified path:

$response->assertJsonPath($path, $expectedValue);

For example, if the following JSON response is returned by your application:

{
    "user": {
        "name": "Steve Schoger"
    }
}

You may assert that the name property of the user object matches a given value like so:

$response->assertJsonPath('user.name', 'Steve Schoger');

assertJsonMissingPath

Assert that the response does not contain the given path:

$response->assertJsonMissingPath($path);

For example, if the following JSON response is returned by your application:

{
    "user": {
        "name": "Steve Schoger"
    }
}

You may assert that it does not contain the email property of the user object:

$response->assertJsonMissingPath('user.email');

assertJsonStructure

Assert that the response has a given JSON structure:

$response->assertJsonStructure(array $structure);

For example, if the JSON response returned by your application contains the following data:

{
    "user": {
        "name": "Steve Schoger"
    }
}

You may assert that the JSON structure matches your expectations like so:

$response->assertJsonStructure([
    'user' => [
        'name',
    ]
]);

Sometimes, JSON responses returned by your application may contain arrays of objects:

{
    "user": [
        {
            "name": "Steve Schoger",
            "age": 55,
            "location": "Earth"
        },
        {
            "name": "Mary Schoger",
            "age": 60,
            "location": "Earth"
        }
    ]
}

In this situation, you may use the * character to assert against the structure of all of the objects in the array:

$response->assertJsonStructure([
    'user' => [
        '*' => [
             'name',
             'age',
             'location'
        ]
    ]
]);

assertJsonValidationErrors

Assert that the response has the given JSON validation errors for the given keys. This method should be used when asserting against responses where the validation errors are returned as a JSON structure instead of being flashed to the session:

$response->assertJsonValidationErrors(array $data, $responseKey = 'errors');

Note
The more generic assertInvalid method may be used to assert that a response has validation errors returned as JSON or that errors were flashed to session storage.

assertJsonValidationErrorFor

Assert the response has any JSON validation errors for the given key:

$response->assertJsonValidationErrorFor(string $key, $responseKey = 'errors');

assertLocation

Assert that the response has the given URI value in the Location header:

$response->assertLocation($uri);

assertContent

Assert that the given string matches the response content:

$response->assertContent($value);

assertNoContent

Assert that the response has the given HTTP status code and no content:

$response->assertNoContent($status = 204);

assertStreamedContent

Assert that the given string matches the streamed response content:

$response->assertStreamedContent($value);

assertNotFound

Assert that the response has a not found (404) HTTP status code:

$response->assertNotFound();

assertOk

Assert that the response has a 200 HTTP status code:

$response->assertOk();

assertPlainCookie

Assert that the response contains the given unencrypted cookie:

$response->assertPlainCookie($cookieName, $value = null);

assertRedirect

Assert that the response is a redirect to the given URI:

$response->assertRedirect($uri);

assertRedirectContains

Assert whether the response is redirecting to a URI that contains the given string:

$response->assertRedirectContains($string);

assertRedirectToRoute

Assert that the response is a redirect to the given named route:

$response->assertRedirectToRoute($name = null, $parameters = []);

assertRedirectToSignedRoute

Assert that the response is a redirect to the given signed route:

$response->assertRedirectToSignedRoute($name = null, $parameters = []);

assertSee

Assert that the given string is contained within the response. This assertion will automatically escape the given string unless you pass a second argument of false:

$response->assertSee($value, $escaped = true);

assertSeeInOrder

Assert that the given strings are contained in order within the response. This assertion will automatically escape the given strings unless you pass a second argument of false:

$response->assertSeeInOrder(array $values, $escaped = true);

assertSeeText

Assert that the given string is contained within the response text. This assertion will automatically escape the given string unless you pass a second argument of false. The response content will be passed to the strip_tags PHP function before the assertion is made:

$response->assertSeeText($value, $escaped = true);

assertSeeTextInOrder

Assert that the given strings are contained in order within the response text. This assertion will automatically escape the given strings unless you pass a second argument of false. The response content will be passed to the strip_tags PHP function before the assertion is made:

$response->assertSeeTextInOrder(array $values, $escaped = true);

assertSessionHas

Assert that the session contains the given piece of data:

$response->assertSessionHas($key, $value = null);

If needed, a closure can be provided as the second argument to the assertSessionHas method. The assertion will pass if the closure returns true:

$response->assertSessionHas($key, function ($value) {
    return $value->name === 'Taylor Otwell';
});

assertSessionHasInput

Assert that the session has a given value in the flashed input array:

$response->assertSessionHasInput($key, $value = null);

If needed, a closure can be provided as the second argument to the assertSessionHasInput method. The assertion will pass if the closure returns true:

$response->assertSessionHasInput($key, function ($value) {
    return Crypt::decryptString($value) === 'secret';
});

assertSessionHasAll

Assert that the session contains a given array of key / value pairs:

$response->assertSessionHasAll(array $data);

For example, if your application's session contains name and status keys, you may assert that both exist and have the specified values like so:

$response->assertSessionHasAll([
    'name' => 'Taylor Otwell',
    'status' => 'active',
]);

assertSessionHasErrors

Assert that the session contains an error for the given $keys. If $keys is an associative array, assert that the session contains a specific error message (value) for each field (key). This method should be used when testing routes that flash validation errors to the session instead of returning them as a JSON structure:

$response->assertSessionHasErrors(
    array $keys, $format = null, $errorBag = 'default'
);

For example, to assert that the name and email fields have validation error messages that were flashed to the session, you may invoke the assertSessionHasErrors method like so:

$response->assertSessionHasErrors(['name', 'email']);

Or, you may assert that a given field has a particular validation error message:

$response->assertSessionHasErrors([
    'name' => 'The given name was invalid.'
]);

Note
The more generic assertInvalid method may be used to assert that a response has validation errors returned as JSON or that errors were flashed to session storage.

assertSessionHasErrorsIn

Assert that the session contains an error for the given $keys within a specific error bag. If $keys is an associative array, assert that the session contains a specific error message (value) for each field (key), within the error bag:

$response->assertSessionHasErrorsIn($errorBag, $keys = [], $format = null);

assertSessionHasNoErrors

Assert that the session has no validation errors:

$response->assertSessionHasNoErrors();

assertSessionDoesntHaveErrors

Assert that the session has no validation errors for the given keys:

$response->assertSessionDoesntHaveErrors($keys = [], $format = null, $errorBag = 'default');

Note
The more generic assertValid method may be used to assert that a response does not have validation errors that were returned as JSON and that no errors were flashed to session storage.

assertSessionMissing

Assert that the session does not contain the given key:

$response->assertSessionMissing($key);

assertStatus

Assert that the response has a given HTTP status code:

$response->assertStatus($code);

assertSuccessful

Assert that the response has a successful (>= 200 and < 300) HTTP status code:

$response->assertSuccessful();

assertUnauthorized

Assert that the response has an unauthorized (401) HTTP status code:

$response->assertUnauthorized();

assertUnprocessable

Assert that the response has an unprocessable entity (422) HTTP status code:

$response->assertUnprocessable();

assertValid

Assert that the response has no validation errors for the given keys. This method may be used for asserting against responses where the validation errors are returned as a JSON structure or where the validation errors have been flashed to the session:

// Assert that no validation errors are present...
$response->assertValid();
// Assert that the given keys do not have validation errors...
$response->assertValid(['name', 'email']);

assertInvalid

Assert that the response has validation errors for the given keys. This method may be used for asserting against responses where the validation errors are returned as a JSON structure or where the validation errors have been flashed to the session:

$response->assertInvalid(['name', 'email']);

You may also assert that a given key has a particular validation error message. When doing so, you may provide the entire message or only a small portion of the message:

$response->assertInvalid([
    'name' => 'The name field is required.',
    'email' => 'valid email address',
]);

assertViewHas

Assert that the response view contains given a piece of data:

$response->assertViewHas($key, $value = null);

Passing a closure as the second argument to the assertViewHas method will allow you to inspect and make assertions against a particular piece of view data:

$response->assertViewHas('user', function (User $user) {
    return $user->name === 'Taylor';
});

In addition, view data may be accessed as array variables on the response, allowing you to conveniently inspect it:

$this->assertEquals('Taylor', $response['name']);

assertViewHasAll

Assert that the response view has a given list of data:

$response->assertViewHasAll(array $data);

This method may be used to assert that the view simply contains data matching the given keys:

$response->assertViewHasAll([
    'name',
    'email',
]);

Or, you may assert that the view data is present and has specific values:

$response->assertViewHasAll([
    'name' => 'Taylor Otwell',
    'email' => 'taylor@example.com,',
]);

assertViewIs

Assert that the given view was returned by the route:

$response->assertViewIs($value);

assertViewMissing

Assert that the given data key was not made available to the view returned in the application's response:

$response->assertViewMissing($key);

Authentication Assertions

Laravel also provides a variety of authentication related assertions that you may utilize within your application's feature tests. Note that these methods are invoked on the test class itself and not the Illuminate\Testing\TestResponse instance returned by methods such as get and post.

assertAuthenticated

Assert that a user is authenticated:

$this->assertAuthenticated($guard = null);

assertGuest

Assert that a user is not authenticated:

$this->assertGuest($guard = null);

assertAuthenticatedAs

Assert that a specific user is authenticated:

$this->assertAuthenticatedAs($user, $guard = null);
