How to Run Phpunit Test In Laravel Controller?

8 minutes read

To run PHPUnit tests in a Laravel controller, first create a test class that extends the Laravel TestCase class. Within this test class, write test methods that will test the different functionalities of the controller.


In each test method, create an instance of the controller and call the specific method that you want to test. Then use assertions to verify that the method behaves as expected.


To run the PHPUnit tests, use the terminal or command prompt to navigate to the Laravel project directory and run the command "php artisan test". This will execute all the tests in the project, including the ones in the controller test class.


Make sure that your controller is properly structured and follows the MVC architecture to ensure that it can be easily tested. Also, use mocking and stubbing techniques to isolate the controller from its dependencies and make the tests more focused on the controller's behavior.

How to run specific PHPUnit tests in a Laravel controller?

To run specific PHPUnit tests in a Laravel controller, you can use the following steps:

  1. First, make sure you have PHPUnit installed in your Laravel application. You can do this by running the following command in your terminal:
1
composer require --dev phpunit/phpunit


  1. Once PHPUnit is installed, you can create a new test class or add your specific tests to an existing test class. For example, you can create a new test file in the tests/Feature directory:
1
php artisan make:test MySpecificTest


  1. Write your specific tests inside the test class. For example:

<?php

namespace Tests\Feature;

use Tests\TestCase;

class MySpecificTest extends TestCase
{
    public function testSpecificFunctionality()
    {
        // Your test code here
        $this->assertTrue(true);
    }
}


  1. To run this specific test, you can use the following command in your terminal:
1
./vendor/bin/phpunit --filter testSpecificFunctionality


Replace testSpecificFunctionality with the name of your specific test method. This command will only run the specified test method.


That's it! You have now successfully run a specific PHPUnit test in a Laravel controller.


How to use PHPUnit assertions in Laravel controller tests?

To use PHPUnit assertions in Laravel controller tests, you can follow these steps:

  1. Create a test class for your controller. This test class should extend the Laravel's TestCase class.
  2. Define test methods inside the test class, each representing a different test case for the controller.
  3. Use PHPUnit assertions inside the test methods to validate the behavior of the controller. For example, you can use methods like assertStatus(), assertJson(), assertRedirect(), assertView(), etc. to check the response returned by the controller.
  4. Make sure to use the proper assertion methods based on the expected behavior of the controller. For example, if you are testing a controller method that should return a JSON response, use assertJson() to validate the response content.
  5. Run your tests using PHPUnit to check if the controller behaves as expected in different scenarios.


Here's an example test class for a controller in Laravel:

<?php

namespace Tests\Feature;

use Tests\TestCase;

class ExampleControllerTest extends TestCase
{
    public function test_index_method_returns_ok_status()
    {
        $response = $this->get('/example');
        
        $response->assertStatus(200);
    }

    public function test_show_method_returns_json_response()
    {
        $response = $this->get('/example/1');
        
        $response->assertStatus(200);
        $response->assertJson([
            'id' => 1,
            'name' => 'Example',
            // Add more expected response data here
        ]);
    }
}


In this example, we have defined two test methods to validate the behavior of the controller's index and show methods. We use assertStatus() to check the status code of the response and assertJson() to validate the JSON response content.


You can run this test class using PHPUnit to verify if the controller is working as expected.


How to write PHPUnit tests for a Laravel controller?

To write PHPUnit tests for a Laravel controller, you can follow these steps:

  1. Create a new test file for your controller. You can place this file inside the "tests" directory of your Laravel project.
  2. In the test file, create a new test class that extends the Laravel TestCase class. This class provides methods for interacting with your Laravel application during testing.
  3. Within the test class, create test methods that will be used to test the various methods of your controller. Use methods provided by the TestCase class, such as get(), post(), and seeJson(), to simulate requests to the controller and check the response.
  4. Set up any necessary data or dependencies before running the tests. You can use the setUp() method provided by the TestCase class to do this.
  5. Run the tests by running the PHPUnit test suite in your Laravel project. You can do this by running the phpunit command in your terminal from the root directory of your Laravel project.


Here is an example of how a test class for a Laravel controller might look like:

use Tests\TestCase;

class UserControllerTest extends TestCase
{
    public function test_get_user()
    {
        $response = $this->get('/user/1');

        $response->assertStatus(200);
        $response->assertJson([
            'id' => 1,
            'name' => 'John Doe',
            'email' => '[email protected]'
        ]);
    }

    public function test_create_user()
    {
        $response = $this->post('/user', [
            'name' => 'Jane Doe',
            'email' => '[email protected]'
        ]);

        $response->assertStatus(201);
        $response->assertJson([
            'name' => 'Jane Doe',
            'email' => '[email protected]'
        ]);
    }
}


In this example, we have a test class for a UserController that contains two test methods, one for getting a user and one for creating a user. The test methods use the get() and post() methods provided by the TestCase class to simulate requests to the controller and check the response using the assertStatus() and assertJson() methods.


Remember to run your tests regularly to ensure that your controller is working as expected and to catch any bugs or regressions early on.


How to run PHPUnit tests with code coverage enabled in Laravel?

To run PHPUnit tests with code coverage enabled in Laravel, follow these steps:

  1. Open your terminal and navigate to the root directory of your Laravel project.
  2. Run the following command to run PHPUnit tests with code coverage enabled:
1
vendor/bin/phpunit --coverage-html=coverage


This command will run all your PHPUnit tests and generate code coverage reports in HTML format in the "coverage" directory.

  1. You can now open the generated HTML code coverage reports in your browser to view the code coverage details.


Note: Ensure that you have PHPUnit installed in your Laravel project. If not, you can install it using Composer by running the following command:

1
composer require --dev phpunit/phpunit


That's it! You have now successfully run PHPUnit tests with code coverage enabled in Laravel.


What is the difference between assertEquals and assertSame in PHPUnit?

In PHPUnit, the assertEquals method is used to check if two values are equal in terms of their content, whereas the assertSame method is used to check if two values are identical in terms of their type and value.


For example:

  • If you have two variables $a = '1'; and $b = 1;, assertEquals would consider them equal because their content is the same, whereas assertSame would consider them not equal because their types are different (string vs integer).
  • If you have two variables $a = $b = new MyClass();, assertEquals would consider them equal if they have the same properties and values, whereas assertSame would consider them not equal because they are separate instances of the same class.


In summary, assertEquals checks for equality by comparing the content of the values, while assertSame checks for identity by comparing the type and value of the values.
