Complete the code to run PHPUnit tests in Laravel using the artisan command.

Laravel

php artisan [1]

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

💡 Hint

Common Mistakes

Using 'serve' instead of 'test' to run tests.

Using 'migrate' which runs database migrations.

Using 'make:test' which creates a new test file.

Use php artisan test to run PHPUnit tests in Laravel.

Complete the code to specify the test directory when running PHPUnit directly.

Laravel

vendor/bin/phpunit [1]

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

Aapp/Http

B--filter

C--coverage

Dtests/Feature

Attempts:

💡 Hint

Common Mistakes

Using '--filter' without a test name.

Using '--coverage' which is for code coverage reports.

Using 'app/Http' which is not a test folder.

Specify the test directory like tests/Feature to run tests in that folder.

Fix the error in the PHPUnit configuration file by completing the missing XML tag.

Laravel

<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="vendor/autoload.php" colors="true">
  <testsuites>
    <testsuite name="Feature">
      <directory>[1]</directory>
    </testsuite>
  </testsuites>
</phpunit>

💡 Hint

Common Mistakes

Pointing to application folders instead of test folders.

Using 'app/Models' or 'resources/views' which are not test directories.

The <directory> tag should point to the folder containing the tests, usually tests/Feature.

4fill in blank

hard

Fill both blanks to create a basic test method in a Laravel test class.

Laravel

public function [1]()
{
    $response = $this->get('/');
    $response->assertStatus([2]);
}

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

B200

C404

Dindex

Attempts:

💡 Hint

Common Mistakes

Using a method name without 'test' prefix.

Asserting status 404 which means not found.

The test method name should start with 'test'. The status code 200 means the page loaded successfully.

5fill in blank

hard

Fill all three blanks to write a test that checks if the home page contains a welcome message.

Laravel

public function [1]()
{
    $response = $this->get('/');
    $response->assertStatus([2]);
    $response->assertSee('[3]');
}

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

B200

CWelcome to Laravel

DtestHome

💡 Hint

Common Mistakes

Using wrong method names.

Checking for wrong status codes.

Looking for incorrect text in the page.

The method name should start with 'test'. Status 200 means success. The string checked is the welcome message.

Practice

1. What is the primary purpose of using PHPUnit in a Laravel project?

easy

A. To test the application and catch bugs early

B. To deploy the application to a server

C. To write database migration scripts

D. To create user interface designs

Solution

1. Step 1: Understand PHPUnit's role

   PHPUnit is a testing framework used to check if code works correctly.

2. Step 2: Connect PHPUnit to Laravel usage

   In Laravel, PHPUnit helps find bugs early by running automated tests.

3. Final Answer:

   To test the application and catch bugs early -> Option A

4. Quick Check:

   Testing = Catch bugs early [OK]

Hint: PHPUnit is for testing, not deployment or design [OK]

Common Mistakes:

• Confusing testing with deployment
• Thinking PHPUnit creates UI or migrations
• Assuming PHPUnit runs the app

2. Which command correctly creates a new test class in Laravel using Artisan?

easy

A. php artisan make:test UserTest

B. php artisan create:test UserTest

C. php artisan test:make UserTest

D. php artisan generate:test UserTest

Solution

1. Step 1: Recall Laravel Artisan test creation command

   The correct command to create a test is php artisan make:test.

2. Step 2: Match the command with options

   Only php artisan make:test UserTest uses the correct syntax: php artisan make:test UserTest.

3. Final Answer:

   php artisan make:test UserTest -> Option A

4. Quick Check:

   Make test command = make:test [OK]

Hint: Use 'make:test' to create tests with Artisan [OK]

Common Mistakes:

• Using incorrect Artisan command verbs
• Mixing test creation with test running commands
• Misspelling 'make:test'

3. Given this test method in Laravel, what will be the output when running php artisan test if the home page returns status 200?

public function test_home_page_status()
{
    $response = $this->get('/');
    $response->assertStatus(200);
}

medium

A. Test fails with status code error

B. Test passes with success message

C. Syntax error in test method

D. Test is skipped automatically

Solution

1. Step 1: Analyze the test method

   The test sends a GET request to '/' and expects HTTP status 200.

2. Step 2: Check expected vs actual response

   If the home page returns 200, the assertion assertStatus(200) passes.

3. Final Answer:

   Test passes with success message -> Option B

4. Quick Check:

   Correct status = test passes [OK]

Hint: If status matches assertStatus, test passes [OK]

Common Mistakes:

• Assuming test fails if status is 200
• Confusing assertStatus with assertSee
• Thinking test skips without reason

4. You wrote this test but it fails with an error:

public function test_example()
{
    $response = $this->get('/home');
    $response->assertStatus(200)
}

What is the likely cause?

medium

A. Test method name is invalid

B. Wrong HTTP method used in get()

C. Missing semicolon after assertStatus(200)

D. Route '/home' does not exist

Solution

1. Step 1: Check syntax in test method

   The line $response->assertStatus(200) lacks a semicolon at the end.

2. Step 2: Understand PHP syntax rules

   Missing semicolon causes a syntax error and test fails to run.

3. Final Answer:

   Missing semicolon after assertStatus(200) -> Option C

4. Quick Check:

   Semicolon missing = syntax error [OK]

Hint: Always end PHP statements with semicolon [OK]

Common Mistakes:

• Ignoring missing semicolon errors
• Assuming wrong HTTP method causes syntax error
• Thinking test method name causes syntax error

5. You want to run only tests related to user authentication in Laravel. Which command helps you run tests in the tests/Feature/AuthTest.php file only?

hard

A. php artisan test --run=AuthTest

B. php artisan make:test AuthTest

C. php artisan test --only=AuthTest

D. php artisan test --filter=AuthTest

Solution

1. Step 1: Identify how to filter tests in Laravel

   Laravel's test command supports --filter to run specific tests.

2. Step 2: Match correct syntax for filtering

   php artisan test --filter=AuthTest uses php artisan test --filter=AuthTest, which runs tests matching 'AuthTest'.

3. Final Answer:

   php artisan test --filter=AuthTest -> Option D

4. Quick Check:

   Filter option runs specific tests [OK]

Hint: Use --filter to run specific test files or methods [OK]

Common Mistakes:

• Using nonexistent options like --only or --run
• Confusing make:test with running tests
• Not specifying filter correctly
