Laravel provides a very fluent API for making HTTP requests to your application and examining the output. 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 testBasicTest()
{
$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.
You may use the withHeaders method to customize the request's headers before it is sent to the application. This allows you to add any custom headers you would like to the request:
<?php
class ExampleTest extends TestCase
{
/**
* A basic functional test example.
*
* @return void
*/
public function testBasicExample()
{
$response = $this->withHeaders([
'X-Header' => 'Value',
])->json('POST', '/user', ['name' => 'Sally']);
$response
->assertStatus(201)
->assertJson([
'created' => true,
]);
}
}
{tip} The CSRF middleware is automatically disabled when running tests.
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
class ExampleTest extends TestCase
{
public function testCookies()
{
$response = $this->withCookie('color', 'blue')->get('/');
$response = $this->withCookies([
'color' => 'blue',
'name' => 'Taylor',
])->get('/');
}
}
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 Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Tests\TestCase;
class ExampleTest extends TestCase
{
/**
* A basic test example.
*
* @return void
*/
public function testBasicTest()
{
$response = $this->get('/');
$response->dumpHeaders();
$response->dumpSession();
$response->dump();
}
}
Laravel provides several helpers for working 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
class ExampleTest extends TestCase
{
public function testApplication()
{
$response = $this->withSession(['foo' => 'bar'])
->get('/');
}
}
One common use of the session is for maintaining state for the authenticated user. 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
use App\User;
class ExampleTest extends TestCase
{
public function testApplication()
{
$user = factory(User::class)->create();
$response = $this->actingAs($user)
->withSession(['foo' => 'bar'])
->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:
$this->actingAs($user, 'api')
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 /user and assert that the expected data was returned:
<?php
class ExampleTest extends TestCase
{
/**
* A basic functional test example.
*
* @return void
*/
public function testBasicExample()
{
$response = $this->postJson('/user', ['name' => 'Sally']);
$response
->assertStatus(201)
->assertJson([
'created' => true,
]);
}
}
{tip} The
assertJsonmethod converts the response to an array and utilizesPHPUnit::assertArraySubsetto 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.
In addition, JSON response data may be accessed as array variables on the response:
$this->assertTrue($response['created']);
If you would like to verify that the given array is an exact match for the JSON returned by the application, you should use the assertExactJson method:
<?php
class ExampleTest extends TestCase
{
/**
* A basic functional test example.
*
* @return void
*/
public function testBasicExample()
{
$response = $this->json('POST', '/user', ['name' => 'Sally']);
$response
->assertStatus(201)
->assertExactJson([
'created' => true,
]);
}
}
If you would like to verify that the JSON response contains some given data at a specified path, you should use the assertJsonPath method:
<?php
class ExampleTest extends TestCase
{
/**
* A basic functional test example.
*
* @return void
*/
public function testBasicExample()
{
$response = $this->json('POST', '/user', ['name' => 'Sally']);
$response
->assertStatus(201)
->assertJsonPath('team.owner.name', 'foo')
}
}
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 testAvatarUpload()
{
Storage::fake('avatars');
$file = UploadedFile::fake()->image('avatar.jpg');
$response = $this->json('POST', '/avatar', [
'avatar' => $file,
]);
// Assert the file was stored...
Storage::disk('avatars')->assertExists($file->hashName());
// Assert a file does not exist...
Storage::disk('avatars')->assertMissing('missing.jpg');
}
}
When creating files using the fake method, you may specify the width, height, and size of the image in order to better test your 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');
Laravel provides a variety of custom assertion methods for your PHPUnit feature tests. These assertions may be accessed on the response that is returned from the json, get, post, put, and delete test methods:
assertCookie assertCookieExpired assertCookieNotExpired assertCookieMissing assertCreated assertDontSee assertDontSeeText assertExactJson assertForbidden assertHeader assertHeaderMissing assertJson assertJsonCount assertJsonFragment assertJsonMissing assertJsonMissingExact assertJsonMissingValidationErrors assertJsonPath assertJsonStructure assertJsonValidationErrors assertLocation assertNoContent assertNotFound assertOk assertPlainCookie assertRedirect assertSee assertSeeInOrder assertSeeText assertSeeTextInOrder assertSessionHas assertSessionHasInput assertSessionHasAll assertSessionHasErrors assertSessionHasErrorsIn assertSessionHasNoErrors assertSessionDoesntHaveErrors assertSessionMissing assertStatus assertSuccessful assertUnauthorized assertViewHas assertViewHasAll assertViewIs assertViewMissing
