单元测试返回一个空的方法

问题描述：

本想单元测试在以下类中的方法

Wanted to Unit Test a method in the following Class

public class DeviceAuthorisationService : IDeviceAuthorisationService
{
    private DeviceDetailsDTO deviceDetailsDTO = null;
    private IDeviceAuthorisationRepositiory deviceAuthorisationRepositiory;

    public DeviceAuthorisationService(IDeviceAuthorisationRepositioryService paramDeviceAuthorisationRepository)
    {
        deviceAuthorisationRepositiory = paramDeviceAuthorisationRepository;
    }

    public void AuthoriseDeviceProfile(long paramUserID, string paramClientMakeModel)
    {
        if (deviceDetailsDTO == null)
            GetCellPhoneDetails(userID);

        if (deviceDetailsDTO.IsDeviceSelected == false)
            throw new SomeCustomExceptionA();

        if (deviceDetailsDTO.CellPhoneMakeModel.ToLower() != paramClientMakeModel.ToLower())
            throw new SomeCustomExceptionB;
    }

    public void UpdateDeviceStatusToActive(long userID)
    {
        if (deviceDetailsDTO == null)
            throw new InvalidOperationException("UnAuthorised Device Profile Found Exception");

        if (deviceDetailsDTO.PhoneStatus != (short)Status.Active.GetHashCode())
            deviceAuthorisationRepositiory.UpdatePhoneStatusToActive(deviceDetailsDTO.DeviceID);
    }

    private void GetCellPhoneDetails(long userID)
    {
        deviceDetailsDTO = deviceAuthorisationRepositiory.GetSelectedPhoneDetails(userID);

        if (deviceDetailsDTO == null)
            throw new SomeCustomException()
    }

}

请注意：

方法名称= AuthoriseDeviceProfile返回void

的方法检查userSentMakeModel对存储在数据库中的匹配

如果它相匹配的 - 它只是返回（即不会改变任何状态）

我们将如何单元测试这种方法吗？

How will we unit test this method?

有嘲笑回购

已经覆盖的抛出异常

问题是所有方案中如何进行单元测试进行得很顺利，即用户; S makeModel与库匹配; S makeModel

Have mocked the Repo
Have covered scenario of "THROWS EXCEPTION"
Question is how to unit test the scenario of ALL WENT WELL ie user;s makeModel matched with repository;s makeModel

任何设计建议，使这个测试的是最欢迎的
先谢谢了。

Any design suggestions to make this testable is most welcome Thanks in advance.

答

由于你的方法返回void，它可能有一定的副作用，你可以测试/断言上。

Since your method returns void, it probably has some side-effect that you can test/assert on.

在你的情况下，选择将是提供 IDeviceAuthorisationRepositioryService 的模拟实例。然后，您可以检查是否为 UpdatePhoneStatusToActive 通话发生。下面是一个使用的解决方案起订量：

In your case, an option would be to provide a mock instance of IDeviceAuthorisationRepositioryService. You can then check if a call to UpdatePhoneStatusToActive has happened. Here is a solution using Moq:

var mock = new Mock<IDeviceAuthorisationRepositioryService>();

var service = new DeviceAuthorisationService(mock.Object);
service.UpdateDeviceStatusToActive(....);

mock.Verify(x => service.UpdatePhoneStatusToActive(), Times.Never());
