问题描述

我正在尝试为 phpunit 模拟一个类.PHP 单元失败并出现错误 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.

I am trying to mock a class for phpunit. Php unit fails with the error Could not load mock ... class already exists. This is the only test I'm running, so it can't be the case that the class is mocked already.

任何建议都将不胜感激.

Any suggestion would be appreciated.

这是错误情况:

namespace TestsFeature;

use TestsTestCase;

class DeactivateACSTest extends TestCase
{
    public function testDeactivateAcs()
    {
        $deviceController = Mockery::mock('overload:AppHttpControllersCloudDeviceController');
        $deviceController
            ->shouldReceive('deactivateACS')
            ->andReturn('hilfehilfehilfe');

        $devCon = new AppHttpControllersCloudDeviceController();
        $this->assertEquals('hilfehilfehilfe', $devCon->deactivateACS());
    }
}

在没有 --code-coverage 的情况下运行它:

When running it without --code-coverage it works:

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


 ==> TestsFeatureDeactivateACSTest              ✓

Time: 1.08 seconds, Memory: 16.00MB

OK (1 test, 3 assertions)

但是，当使用 --code-coverage 运行它时，它会失败:

However, when running it with --code-coverage it fails:

[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.


  ==> TestsFeatureDeactivateACSTest              ⚈

Time: 5.79 seconds, Memory: 44.00MB

There was 1 error:

1) TestsFeatureDeactivateACSTest::testDeactivateAcs

推荐答案

您应该在模拟此类的函数之前添加这些注释.

You should add these annotations before the functions that are mocking this class.

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

您可以查看 phpunit 文档作为参考.

For reference you can check out the phpunit documentation.

https://phpunit.de/manual/当前/en/appendixes.annotations.html#appendixes.annotations.runInSeparateProcess

https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.preserveGlobalState
