Create and Running Tests

Introduction
• Laravel was born with testing in its DNA. In fact, Laravel supports PHPUnit for testing by default, and has a phpunit.xml file configured for your application. The framework also provides some convenient helper functions so that you can test your application more intuitively.
By default, your application's

directory contains two subdirectories: Feature and

test example file is provided in both the

and Unit directories. After installing a new Laravel application, run the phpunit command from the command line to run the tests.

Environment

When using phpunit for testing, Laravel will automatically set the environment to testing based on the environment variables set in the phpunit.xml file , and store the Session and cache in the form of array, which means that no Session or cache data will be persisted during testing.

You can create other necessary test environment configurations at will. testing Environment variables can be modified in the phpunit.xml file, but before running the test, make sure to clear the cache of configuration information using the config:clear Artisan command !

In addition, you can also create a .env.testing file in the root directory of your project to run unit tests, or use the command with --env=testing# When using the Artisan command with the ## option, the variables in the .env file will be overwritten by this file.

// 在 Feature 目录下创建一个测试类...php artisan make:test UserTest// 在 Unit 目录下创建一个测试类...php artisan make:test UserTest --unit

<?php
    namespace Tests\Unit;
    use Tests\TestCase;
    use Illuminate\Foundation\Testing\RefreshDatabase;
    class ExampleTest extends TestCase{   
     /**
     * 一个基本的测试示例。
     *
     * @return void
     */   
    public function testBasicTest()  
      {      
        $this->assertTrue(true);  
       }
    }
