laravel:单元测试之model(10.27.0)

一，相关文档

https://learnku.com/docs/laravel/10.x/testing/14895

二，php代码

1，查看laravel自带的phpunit的版本

liuhongdi@lhdpc:/data/laravel/dignews$ ./vendor/bin/phpunit --version
PHPUnit 10.4.1 by Sebastian Bergmann and contributors.

2，创建测试类:

liuhongdi@lhdpc:/data/laravel/dignews$ php artisan make:test SUserTest --unit

   INFO  Test [tests/Unit/SUserTest.php] created successfully.

3,测试类的代码:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

<?php   namespace Tests\Unit;   use Illuminate\Database\Eloquent\Model; //use PHPUnit\Framework\TestCase; use App\Models\SUser; use Tests\TestCase;   class SUserTest extends TestCase {     /**      * A basic unit test example.      */     public function test_example(): void     {         //得到数据         $model = new SUser();         $obj = $model->getOneById(1);         //断言         $userId = $obj['user_id'];         $userName = $obj['username'];         $this->assertEquals(1, $userId);         $this->assertEquals('laoliu', $userName);     } }

三，测试效果

liuhongdi@lhdpc:/data/laravel/dignews$ vendor/bin/phpunit --filter=SUserTest
PHPUnit 10.4.1 by Sebastian Bergmann and contributors.
Runtime:       PHP 8.1.1
Configuration: /data/laravel/dignews/phpunit.xml
.                                                                   1 / 1 (100%)
Time: 00:00.096, Memory: 24.00 MB
OK (1 test, 2 assertions)

四，可能出现的报错:

1，报错

1) Error: Call to a member function connection() on null

2，解决:

在测试类中:

注释掉下面一行,如下

//use PHPUnit\Framework\TestCase;

添加Tests\TestCase,如下,

use Tests\TestCase;

3,原因:

检查测试类，它需要在扩展使用 Tests\TestCase; 
而不是使用 PHPUnit\Framework\TestCase;(laravel默认使用的类)
Tests\TestCase类负责设置应用程序，
如果使用PHPunit\Framework\TestCase，模型将无法与数据库通信。

五,查看laravel框架的版本:

liuhongdi@lhdpc:/data/laravel/dignews$ php artisan --version
Laravel Framework 10.27.0
