What does this Laravel HTTP test assertion check?

Consider this Laravel test code snippet:

$response = $this->get('/home');
$response->assertStatus(200);

What does the assertStatus(200) method verify in this test?

Laravel

$response = $this->get('/home');
$response->assertStatus(200);

A It verifies that the response contains the text '200'.

B It checks that the HTTP response status code is exactly 200 (OK).

C It asserts that the response has a JSON body with a 'status' key equal to 200.

D It confirms that the response redirects to a URL containing '200'.

💡 Hint

The number inside assertStatus refers to the HTTP status code returned by the server.

The assertStatus method checks the HTTP status code returned by the response. Passing 200 means the test expects a successful OK response.

Which option correctly asserts JSON structure in Laravel HTTP test?

You want to test that the JSON response contains a key 'user' with a nested key 'name'. Which assertion syntax is correct?

Laravel

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

A $response->assertJsonHas('user.name', 'John');

B $response->assertJsonContains(['user.name' => 'John']);

C $response->assertJsonPath('user.name', 'John');

D $response->assertJson(['user' => ['name' => 'John']]);

💡 Hint

Use assertJson with an array matching the expected JSON structure.

assertJson expects an array that matches part of the JSON response. Nested arrays represent nested JSON objects.

Why does this Laravel HTTP test fail with a 500 error?

Given this test code:

$response = $this->post('/login', ['email' => '[e-mail]']);
$response->assertStatus(302);

The test fails with a 500 Internal Server Error instead of 302 redirect. What is the most likely cause?

Laravel

$response = $this->post('/login', ['email' => '[e-mail]']);
$response->assertStatus(302);

A The assertStatus method is used incorrectly; it should be assertRedirect.

B The route '/login' does not exist, so the server returns 500.

C The POST request is missing the required 'password' field, causing a server error.

D The test client does not support POST requests, causing the error.

💡 Hint

Check if all required form fields are included in the POST data.

A 500 error often means the server code crashed. Missing required input like 'password' can cause this in login logic.

What is the value of $response->headers->get('Content-Type') after this test?

In a Laravel test:

$response = $this->get('/api/data');
$contentType = $response->headers->get('Content-Type');

If the API returns JSON, what is the expected value of $contentType?

Laravel

$response = $this->get('/api/data');
$contentType = $response->headers->get('Content-Type');

A 'application/json; charset=utf-8'

B 'text/html; charset=UTF-8'

C 'application/xml'

D 'text/plain'

💡 Hint

APIs returning JSON usually set Content-Type to application/json.

Laravel sets the Content-Type header to 'application/json; charset=utf-8' for JSON responses by default.

Which Laravel HTTP test assertion ensures a redirect to a named route?

You want to test that a response redirects to a route named 'dashboard'. Which assertion method and argument correctly verify this?

Laravel

$response = $this->post('/login', ['email' => '[e-mail]', 'password' => 'secret']);

A $response->assertRedirect(route('dashboard'));

B $response->assertLocation('dashboard');

C $response->assertRedirect('/dashboard');

D $response->assertRouteIs('dashboard');

💡 Hint

Use the route() helper to get the URL for a named route.

assertRedirect expects a URL. Using route('dashboard') generates the URL for the named route 'dashboard'.
