PHPUnit-为什么预期的方法调用不'；不行？

OrderHelper类正在使用OrderRepository类更新订单（通过

save

方法）。我试图测试在

OrderHelper:：saveOrderSource

中是否调用了

OrderRepository:：save

但它一直在说：

调用1次时，方法名称等于“save”的预期失败。 方法应被调用1次，实际调用0次

请帮忙

setUp（）方法：

protected function setUp()
{
    $objectManager          = new ObjectManager($this);

    $this->orderRepository = $this->getMockBuilder(OrderRepositoryInterface::class)
        ->setMethods(['save','getList','get','delete'])
        ->disableOriginalConstructor()
        ->getMock();

    $this->helper = $objectManager->getObject(
        OrderHelper::class,
        [
            'orderRepository' => $this->orderRepository
        ]
    );
}

public function testSave()
{
    $order = $this->createMock(OrderInterface::class);

    $this->orderRepository->expects($this->once())
        ->method('save')
        ->with($order)
        ->willReturn($this->helper);

    $this->helper->saveOrderSource($order, 1);
}

public function saveOrderSource(OrderInterface $order, $source = null) : OrderHelper
{
    if(!is_null($order) && !$source){
        $order->setOrderSource($source);
        $this->orderRepository->save($order);
    }

    return $this;
}

测试类：

protected function setUp()
{
    $objectManager          = new ObjectManager($this);

    $this->orderRepository = $this->getMockBuilder(OrderRepositoryInterface::class)
        ->setMethods(['save','getList','get','delete'])
        ->disableOriginalConstructor()
        ->getMock();

    $this->helper = $objectManager->getObject(
        OrderHelper::class,
        [
            'orderRepository' => $this->orderRepository
        ]
    );
}

public function testSave()
{
    $order = $this->createMock(OrderInterface::class);

    $this->orderRepository->expects($this->once())
        ->method('save')
        ->with($order)
        ->willReturn($this->helper);

    $this->helper->saveOrderSource($order, 1);
}

public function saveOrderSource(OrderInterface $order, $source = null) : OrderHelper
{
    if(!is_null($order) && !$source){
        $order->setOrderSource($source);
        $this->orderRepository->save($order);
    }

    return $this;
}

OrderHelper:：saveOrderSource:中的原始方法：

protected function setUp()
{
    $objectManager          = new ObjectManager($this);

    $this->orderRepository = $this->getMockBuilder(OrderRepositoryInterface::class)
        ->setMethods(['save','getList','get','delete'])
        ->disableOriginalConstructor()
        ->getMock();

    $this->helper = $objectManager->getObject(
        OrderHelper::class,
        [
            'orderRepository' => $this->orderRepository
        ]
    );
}

public function testSave()
{
    $order = $this->createMock(OrderInterface::class);

    $this->orderRepository->expects($this->once())
        ->method('save')
        ->with($order)
        ->willReturn($this->helper);

    $this->helper->saveOrderSource($order, 1);
}

public function saveOrderSource(OrderInterface $order, $source = null) : OrderHelper
{
    if(!is_null($order) && !$source){
        $order->setOrderSource($source);
        $this->orderRepository->save($order);
    }

    return $this;
}

我认为你应该添加这个代码

    $this->orderRepository->expects($this->once())
        ->method('save')
        ->with($order)
        ->willReturn($this->helper);

在下一行之前的设置中

$this->helper = $objectManager->getObject(
