Practice - 5 Tasks

1fill in blank

easy

Complete the code to assert the HTTP response status is 200.

Laravel

response()->get('/home')->assert[1](200);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using a method that does not exist like 'status' or 'checkStatus'.

Forgetting to call the method with parentheses.

The assertStatus method checks the HTTP response status code.

2fill in blank

medium

Complete the code to assert the response contains the text 'Welcome'.

Laravel

response()->get('/')->assert[1]('Welcome');

Drag options to blanks, or click blank then click option'

AcheckText

CcontainsText

DSee

💡 Hint

Common Mistakes

Using methods that do not exist like 'hasText' or 'checkText'.

Confusing assertSee with assertDontSee.

The assertSee method checks if the response contains the given text.

3fill in blank

hard

Complete the code to assert the response JSON has a key 'success'.

Laravel

response()->get('/api/test')->assert[1](['success']);

Drag options to blanks, or click blank then click option'

AJsonStructure

BJsonHas

ChasJsonKey

DJsonFragment

Attempts:

💡 Hint

Common Mistakes

Using non-existent methods like 'JsonHas' or 'hasJsonKey'.

Passing a string instead of an array.

The assertJsonStructure method checks if the JSON response has the given keys.

4fill in blank

hard

Fill both blanks to assert the response redirects to '/dashboard' and has a session key 'status'.

Laravel

response()->post('/login')->assert[1]('/dashboard')->assert[2]('status');

Drag options to blanks, or click blank then click option'

AredirectTo

BRedirect

CSessionHas

DhasSession

Attempts:

💡 Hint

Common Mistakes

Using wrong method names like 'redirectTo' or 'hasSession'.

Mixing up redirect and session assertions.

assertRedirect checks the redirect URL, and assertSessionHas checks for the session key.

5fill in blank

hard

Fill all three blanks to assert the response has JSON with key 'user', the 'name' field equals 'Alice', and status 201.

Laravel

response()->post('/api/users')->assert[1](['user'])->assertJsonPath('user.name', [2])->assert[3](201);

Drag options to blanks, or click blank then click option'

AJsonStructure

B'Alice'

CStatus

DJsonFragment

Attempts:

💡 Hint

Common Mistakes

Using assertJsonFragment instead of assertJsonStructure for keys.

Forgetting quotes around 'Alice'.

Mixing up status assertion method.

assertJsonStructure checks the JSON keys, assertJsonPath checks the value at a path, and assertStatus checks the HTTP status code.

Practice

1. Which Laravel HTTP test assertion checks if the response status code is 200?

easy

A. $response->assertStatus(200);

B. $response->assertRedirect('/home');

C. $response->assertSee('Welcome');

D. $response->assertJson(['success' => true]);

Solution

1. Step 1: Understand the purpose of assertStatus

   This method checks the HTTP status code returned by the response.

2. Step 2: Match the status code 200 with the assertion

   $response->assertStatus(200); confirms the response was successful (OK).

3. Final Answer:

   $response->assertStatus(200); -> Option A

4. Quick Check:

   Check status code = assertStatus(200) [OK]

Hint: Use assertStatus(200) to check for OK response quickly [OK]

Common Mistakes:

• Confusing assertRedirect with assertStatus
• Using assertSee to check status code
• Expecting assertJson to check status

2. Which of the following is the correct syntax to assert a redirect to the URL '/dashboard' in a Laravel HTTP test?

easy

A. $response->assertLocation('/dashboard', 200);

B. $response->redirect('/dashboard');

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

D. $response->assertStatus(302, '/dashboard');

Solution

1. Step 1: Identify the correct assertion method for redirects

   Laravel uses assertRedirect() to check if the response redirects to a given URL.

2. Step 2: Confirm the syntax matches the method signature

   The correct syntax is $response->assertRedirect('/dashboard'); which asserts a redirect to '/dashboard'.

3. Final Answer:

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

4. Quick Check:

   Redirect assertion = assertRedirect(url) [OK]

Hint: Use assertRedirect('url') to check redirects in tests [OK]

Common Mistakes:

• Using assertStatus with URL parameter
• Calling redirect() instead of assertRedirect()
• Using assertLocation with incorrect status code

3. Given the following test code:

$response = $this->get('/welcome');
$response->assertStatus(200);
$response->assertSee('Hello World');

What will happen if the page '/welcome' returns status 404?

medium

A. The test will fail on assertSee because the content is missing.

B. The test will pass because assertSee ignores status codes.

C. The test will throw a syntax error.

D. The test will fail on assertStatus(200) because the status is 404.

Solution

1. Step 1: Analyze the response status code

   The response returns 404, which means 'Not Found', not 200.

2. Step 2: Understand the effect of assertStatus(200)

   This assertion expects a 200 status code, so it will fail when the actual status is 404.

3. Final Answer:

   The test will fail on assertStatus(200) because the status is 404. -> Option D

4. Quick Check:

   Status mismatch causes assertStatus failure [OK]

Hint: Check status code first; assertStatus fails if codes differ [OK]

Common Mistakes:

• Assuming assertSee passes regardless of status
• Expecting syntax errors from valid code
• Ignoring the importance of status code in tests

4. You wrote this test:

$response = $this->post('/login', ['email' => '[e-mail]', 'password' => 'secret']);
$response->assertRedirect('/dashboard');
$response->assertStatus(200);

Why does this test fail even though the redirect is correct?

medium

A. Because the post method should be get for redirects.

B. Because assertStatus(200) conflicts with the redirect status code 302.

C. Because the URL '/dashboard' is incorrect.

D. Because assertRedirect must come after assertStatus.

Solution

1. Step 1: Understand HTTP redirect status codes

   Redirect responses usually have status code 302, not 200.

2. Step 2: Check the conflict between assertions

   assertRedirect('/dashboard') expects a 302 status, but assertStatus(200) expects 200, causing failure.

3. Final Answer:

   Because assertStatus(200) conflicts with the redirect status code 302. -> Option B

4. Quick Check:

   Redirect status is 302, not 200 [OK]

Hint: Redirects use 302 status; don't assert 200 with assertRedirect [OK]

Common Mistakes:

• Mixing HTTP methods for redirect tests
• Assuming assertRedirect changes status code
• Thinking assertion order affects results

5. You want to test that a JSON API response contains a key 'status' with value 'success' and also returns HTTP status 201. Which assertion combination is correct?

hard

A. $response->assertStatus(201)->assertJson(['status' => 'success']);

B. $response->assertJson(['status' => 'success'])->assertRedirect(201);

C. $response->assertStatus(200)->assertJson(['status' => 'success']);

D. $response->assertSee('success')->assertStatus(201);

Solution

1. Step 1: Identify the correct status code assertion

   HTTP 201 means 'Created', so assertStatus(201) is needed.

2. Step 2: Use assertJson to check JSON content

   assertJson(['status' => 'success']) verifies the JSON key and value.

3. Step 3: Combine assertions correctly

   Chaining assertStatus(201) and assertJson([...]) is valid and checks both conditions.

4. Final Answer:

   $response->assertStatus(201)->assertJson(['status' => 'success']); -> Option A

5. Quick Check:

   Status 201 + JSON key check = assertStatus + assertJson [OK]

Hint: Chain assertStatus(201) with assertJson for API success checks [OK]

Common Mistakes:

• Using assertRedirect with status code
• Checking status 200 instead of 201
• Using assertSee for JSON content
