当使用--code-coverage运行时，模拟失败并显示“无法加载模拟...类已存在”

Question

我正在尝试模拟phpunit的类。php单元因错误而失败Could not load mock ... class already exists。这是我正在运行的唯一测试，因此不可能已经模拟了该类。

任何建议，将不胜感激。

这是错误情况：

namespace Tests\Feature;

use Tests\TestCase;

class DeactivateACSTest extends TestCase
{
    public function testDeactivateAcs()
    {
        $deviceController = \Mockery::mock('overload:App\Http\Controllers\Cloud\DeviceController');
        $deviceController
            ->shouldReceive('deactivateACS')
            ->andReturn('hilfehilfehilfe');

        $devCon = new \App\Http\Controllers\Cloud\DeviceController();
        $this->assertEquals('hilfehilfehilfe', $devCon->deactivateACS());
    }
}

在没有--code-coverage它的情况下运行时：

[13:10:15] vagrant@homestead [~/Code/ekp] $ phpunit --filter DeactivateACS
PHPUnit 6.5.10 by Sebastian Bergmann and contributors.


 ==> Tests\Feature\DeactivateACSTest              ?

Time: 1.08 seconds, Memory: 16.00MB

OK (1 test, 3 assertions)

但是，与--code-coverage它一起运行时失败：

[13:10:23] vagrant@homestead [~/Code/ekp] $ phpunit --coverage-html coverage --coverage-text=code_coverage.txt --filter DeactivateACSTest
PHPUnit 6.5.10 by Sebastian Bergmann and contributors.


  ==> Tests\Feature\DeactivateACSTest              ?

Time: 5.79 seconds, Memory: 44.00MB

There was 1 error:

1) Tests\Feature\DeactivateACSTest::testDeactivateAcs

您应该在模拟此类的函数之前添加这些注释。

/**
 * @runInSeparateProcess
 * @preserveGlobalState disabled
 */

作为参考，您可以查看phpunit文档。
