Mock不适用于发电机？

如果您像生成器一样使用它，它会起作用：

    $mock = $this->getMockBuilder(SomeClass::class)
        ->setMethods(['method1'])
        ->getMock();
    $mock->expects($this->once())
        ->method('method1')
        ->willReturn('');
    foreach ($mock->method2() as $result) {
        var_dump($result);
    }

而不是：

    $mock = $this->getMockBuilder(SomeClass::class)
        ->setMethods(['method1'])
        ->getMock();
    $mock->expects($this->once())
        ->method('method1')
        ->willReturn('');
    $result = call_user_func([$mock, 'method2']);
    var_dump($result);
