Writing and running a test case

In this recipe, if we already have the PHPUnit installed and working, we can write a test case and use PHPUnit to check if it is valid or not.

Getting ready

To run a test case, we'll need a working installation of Laravel. We'll also need to have installed PHPUnit from the previous recipe, Setting up and configuring PHPUnit.

How to do it...

To complete this recipe, follow the given steps:

1. In the app/tests directory, create a file named MyAppTest.php with the following code:

     <?php
   class MyAppTest extends TestCase {
   
     /**
      * Testing the MyApp route
      *
      * @return void
      */
     public function testMyAppRoute()
   {
     $response = $this->call('GET', 'myapp');
     $this->assertResponseOk();
     $this->assertEquals('This is my app', $response >getContent());
   }
   }

2. Run the tests in the command line window, and we should get failing tests on entering the following command:

     vendor/bin/phpunit
   

3. In our routes.php file, add a new route with the following code:
