如何将 mockRepository return 方法设置为 return IEnumerable<T>？
How can I setup the mockRepository return method to return an IEnumerable<T>?
我是最小起订量的新手，之前我已经完成了一些编码，但这次我需要 return 我创建的任务列表中的 2 个对象。我尝试使用 mockRepository.SetReturnsDefault() 命令，但不知何故它不能像我编程的那样工作。我正在使用这个创建两个不同任务的测试，我只需要更新我创建的第一个任务 (taskPrev)。
我创建了一个处理程序来处理异常，这样我就不能创建与其他任务和其他业务规则重叠的任务，并且该测试我正在尝试更新以前的任务并且应该 return 成功但是当我 运行 测试它时 return 我添加到列表任务的所有任务，即使我正在使用一个函数来过滤这些任务。
我用来过滤的部分是 var tasks = await _repository.FindBy(x => x.Id != command.Id); 但它只是 return 所有两个任务而没有过滤它。
我想知道我是否以错误的方式使用最小起订量，或者是其他原因，因为我已经搜索了很多 fo运行，但没有找到任何可以帮助我的东西。
这是我将最小起订量配置为 return 列表的方式：
//Criar 1ª Task
Task taskPrev = new Task(taskTypeId, projectId, costCenterId, Convert.ToDateTime(date),
startHour, startMinute, endHour, endMinute, workItem, timeSheetId, description);
taskPrev.Id = taskId;
//Criar 2ª Task
Task taskCurr = new Task(taskTypeId, projectId, costCenterId, Convert.ToDateTime(date),
endHour, startMinute, Convert.ToByte(endHour + 1), endMinute, workItem, timeSheetId, description);
taskCurr.Id = taskId + 1;
List<Task> tasks = new List<Task>();
tasks.Add(taskPrev);
tasks.Add(taskCurr);
// mockRepository.SetReturnsDefault(System.Threading.Tasks.Task.FromResult((IEnumerable<Task>)tasks));
mockRepository.Setup(x => x.FindBy(x => It.IsAny<IAsyncRepository<Task>>())).Returns(System.Threading.Tasks.Task.FromResult((IEnumerable<Task>)tasks.Where(x => x.Id == taskCurr.Id)));
使用mockRepository.SetReturnsDefault() return两个任务并且不过滤；
使用 mockRepository.SetReturnsDefault() 和 mockRepository.Setup() 与仅使用 SetReturnsDefault() 相同；
并且只使用 mockRepository.Setup() return 空.

我认为您对如何在 Setup 方法中定义预期参数感到困惑。
为了说明问题，让我们看一下不涉及 lambda 的设置：
var myMock = new Mock<IMyThing>();
myMock.Setup(m => m.GetById(7)).Returns(new Thing());
这是调用 GetById 的设置，其中参数恰好为 7。如果您正在测试的代码调用 GetById(7)，它将获得一个 Thing 对象。如果调用代码传递的不是 7，则不会匹配设置，并且 return 将为空。
您可以使用 It.IsAny():
使您的设置更加灵活
var myMock = new Mock<IMyThing>();
myMock.Setup(m => m.GetById(It.IsAny<int>())).Returns(new Thing());
现在，您的调用代码传递给 GetById() 的整数无关紧要 - 设置将始终匹配，并且您将始终得到一个非空的事物。
理解到位后，让我们看看您的设置：
mockRepository.Setup(x => x.FindBy(x => It.IsAny<IAsyncRepository<Task>>())).Returns(//stuff);
FindBy 方法采用 Func<Task,bool> 类型的谓词，您在这里提供了一个特定的谓词：x => It.IsAny<IAsyncRepository<Task>>()。因为您提供了一个特定的参数值，所以调用代码必须与该特定参数完全匹配，否则设置将不匹配。您的调用代码传递给 FindBy 的谓词不匹配，因为 (x => x.Id != command.Id) != (x => It.IsAny<IAsyncRepository<Task>>())，并且由于设置不匹配，您 return null（或者如果已调用 SetReturnsDefault，它将 return 无论默认 return 是什么。
如果您希望您的设置匹配您的调用代码可能发送的任何 lambda，它应该如下所示：
mockRepository.Setup(x => x.FindBy(It.IsAny<Func<Task,bool>>())).Returns(//stuff);
