嘲弄失败，“无法加载模拟...类已经存在”与--code覆盖运行时

Question

我试图嘲弄一类PHPUnit的。 PHP单元失败，出现错误Could not load mock ... class already exists。这是我跑的唯一的测试，所以它不能被该类已经被嘲笑的情况。

任何建议，将不胜感激。

以下是错误的情况下：

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());
    }
}

当运行它没有--code-coverage它的工作原理：

[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)

然而，随着--code-coverage它不能运行时：

[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
Mockery\Exception\RuntimeException: Could not load mock \App\Http\Controllers\Cloud\DeviceController, class already exists

你应该被嘲讽这个类的功能之前添加这些注释。

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

仅供参考，你可以检查出PHPUnit文档。

我遇到了同样的问题，固定这样的： 1.在我的单元测试的另一个测试（不嘲弄测试）中具有上有我在嘲笑类的PHP文件require_once。删除了该行。 2.增加processIsolation =“真”，在测试套件
