Question

我有类似的东西要测试：

public void example(ModelView modelView)
        {
            //...
            var statustId= 1; 
            var requests = _unitOfWork.RequestRepository.Get(m => m.RequestStatusId == statusId);

            var requests = _unitOfWork.RequestRepository.Get(m => m.RequestTypeId == modelView.RequestTypeId);

            var oldRequests = _unitOfWork.RequestRepository.Get(m => m.Created == DateTime.Now.AddDays(-7));
            //...
        }

我如何模仿所有＆＃34; GET＆＃34;有不同的数据？

这是我到目前为止所做的：不确定表达式应该是什么样子，因为它使用了函数中的变量。

[Test]
public void Test()
{
    //Arrange
    _requestGenericRepo.Setup(m => m.Get(
      It.Is<Expression<Func<Request, bool>>>(e => e.Equals(First GET - using local variable);
    _requestGenericRepo.Setup(m => m.Get(
      It.Is<Expression<Func<Request, bool>>>(e => e.Equals(Second GET - using variable from modelView));
    _requestGenericRepo.Setup(m => m.Get(
      It.Is<Expression<Func<Request, bool>>>(e => e.Equals(Third GET));
    //Act
    var response = _controller.Example( new ModelView
    {
       RequestTypeId= 1
    }); 
    //Assert
    ...
}

以上述方式知道如何做会很好，但我可以将所有Get(更改为Get().Where，如下所示：

public void example(ModelView modelView)
        {
            //...
            var statustId= 1; 
            var requests = _unitOfWork.RequestRepository.Get().Where(m => m.RequestStatusId == statusId);

            var requests = _unitOfWork.RequestRepository.Get().Where(m => m.RequestTypeId == modelView.RequestTypeId);

            var oldRequests = _unitOfWork.RequestRepository.Get().Where(m => m.Created == DateTime.Now.AddDays(-7));
            //...
        }


[Test]
public void Test()
{
    //Arrange
    _requestGenericRepo.Setup(m => m.Get(
      It.IsAny<Expression<Func<Request, bool>>>());

    //Act
    var response = _controller.Example( new ModelView
    {
       RequestTypeId= 1
    }); 
    //Assert
    ...
}

RequestRepository.Get方法的返回值是多少？您可以尝试使用SetupSequence并选择要测试的路径。类似的东西：

 _requestGenericRepo.SetupSequence(m => m.Get(It.IsAny<Expression<Func<Request, bool>>>())
    .Returns(/*First call*/)
    .Returns(/*Second call*/)
    .Returns(/*Third call*/);
