如何在 codeception yii2 测试中使用 PhpUnit mocking 方法

Question

I need to use PHPUnit mocking methods like expect($this->once())->returnSelf(); in codecept/yii2 tests. Cannot find any way to call them. The Stub library of codeception does not have as many way to mock a method.

Although phpunit is wrapped by codeception I neither can find a way to use phpunit with yii 2 for API testing using sendPost etc.

Please suggest.

The Codeception\Test\Unit class indirectly extends PHPUnit\Framework\TestCase . You should be able to use PHPUnit way of creating mock object and then you can set up its methods:

public function testMyTestCase()
{
    $mockedObject = $this->createMock(MockedClassOrInterface::class);
    $mockedObject->expects($this->once())
        ->method('methodName')
        ->willReturnSelf();
    // ... rest of the test case code
}
