Static Mock Help

[zach davis]

Hey everyone,

I am trying to do some static mocking.  here is my test.

[Test]
       public void timesheet_processor_tests_just_mock()
       {
           Mock.SetupStatic(typeof(LaborManager));
           Mock.Arrange(() => LaborManager.GetTimesheetLabor(DateTime.Now, 1683)).Returns(new TimesheetLaborReadOnlyCollection());
           var processor = new TimesheetProcessor();
           processor.ProcessUserTimesheet(DateTime.Now, 1683);
           Mock.Assert(() => LaborManager.GetTimesheetLabor(DateTime.Now, 1683), Occurs.AtLeastOnce());
       }

The class TimesheetProcessor uses LaborManager.GetTimesheetLabor() method which I have setup to return a new Collection which by Default would have a count == 0. 

However, when I step into this and get into the TimesheetProcessor class where LaborManager.GetTimeSheetLabor() method is called.  the variable laborEntries which calls the method I arranged in my test gets set to null instead of a new collection.  Please see the timesheet processor code below

//Timesheet Processor Class
        public void ProcessUserTimesheet(DateTime weekEndingDate, int userId)
        {
            TimesheetsCreated = new List<int>();
            TimesheetLaborReadOnlyCollection laborEntries = LaborManager.GetTimesheetLabor(weekEndingDate, userId);
            if(laborEntries.Count > 0)
                ProcessTimesheetLaborUser(userId, weekEndingDate, laborEntries);
        }

Why is this happening?
Have I setup my test incorrectly?

I have JustMock enabled.

Thanks,

Hi zach,

Thank you for submitting the issue. However, DateTime is a value type. Therefore, the DateTime.Now that is passed in ProcessUserTimeSheet and the DateTime.Now that is used to assert the call contains different value.

I updated the test code in the following way and the test is passing as expected:

[Test]
public void timesheet_processor_tests_just_mock()
{
    var currentDate = DateTime.Now;
    Mock.SetupStatic(typeof(LaborManager));
    Mock.Arrange(() => LaborManager.GetTimesheetLabor(currentDate, 1683)).Returns(new TimesheetLaborReadOnlyCollection());
    var processor = new TimesheetProcessor();
    processor.ProcessUserTimesheet(currentDate, 1683);
    Mock.Assert(() => LaborManager.GetTimesheetLabor(currentDate, 1683), Occurs.AtLeastOnce());
}

I also attached the test project to let you have a look. Please feel free to write back if you are facing further issues.
