在MSTEST中断言集合OrderBy正常工作

Question

早上好。我正在编写一个单元测试，以验证我的API处理程序是否正确地对集合进行排序。正如您所看到的，它是模拟的数据，为了测试OrderBy功能，我故意创建测试数据。一旦处理程序返回DTO集合，我希望验证"act“集合是否与我的"expectedDTO”集合的顺序相同。下面是代码：

    [TestMethod]
    public async Task GetByDay_ReturnsDtoList_WhenFound()
    {
        var testData = TestMethodData(); 
        var expectedCalendarDto = ExpectedDto();
        var testCalendar = testData;
        var query = new GetCalendarByDaysQuery();

        _mockCalendarRepo.Setup(m => m.GetItemsAsync(It.IsAny<ISpecification<CalendarDay>>(), null, null))
            .ReturnsAsync(testCalendar);
        var sut = new GetCalendarByDaysHandler(_mockCalendarRepo.Object, _mapper);
        var act = await sut.HandleAsync(query);

        Assert.IsNotNull(act);
        Assert.IsInstanceOfType(act, typeof(IEnumerable<CalendarDto>));
        Assert.AreEqual(expectedCalendarDto, act);
    }

    private GetItemsResult<IEnumerable<CalendarDay>> TestMethodData()
    {
        var testData = new GetItemsResult<IEnumerable<CalendarDay>>();
        testData.ContinuationToken = null;

        testData.Results = new List<CalendarDay>()
        {
            new CalendarDay { Id = "4-5-4|2021-04-01", FiscalYear = 2021, CalendarType = "4-5-4", Quarter = 2, Period = 4, CalendarDate = "2021-04-01", WeekOfYear = 13, DayOfYear = 61, WeekOfPeriod = 1 },
            new CalendarDay { Id = "4-5-4|2021-08-01", FiscalYear = 2021, CalendarType = "4-5-4", Quarter = 3, Period = 8, CalendarDate = "2021-08-01", WeekOfYear = 24, DayOfYear = 121, WeekOfPeriod = 1 },
            new CalendarDay { Id = "4-5-4|2021-01-01", FiscalYear = 2021, CalendarType = "4-5-4", Quarter = 1, Period = 1, CalendarDate = "2021-01-01", WeekOfYear = 1, DayOfYear = 1, WeekOfPeriod = 1 }
        };
        return testData;
    }

    private IEnumerable<CalendarDto> ExpectedDto()
    {
        var testDto = new List<CalendarDto>()
        {
            new CalendarDto {  FiscalYear = 2021, CalendarType = "4-5-4", Quarter = 1, Period = 1, CalendarDate = "2021-01-01", WeekOfYear = 1, DayOfYear = 1, WeekOfPeriod = 1 },
            new CalendarDto {  FiscalYear = 2021, CalendarType = "4-5-4", Quarter = 2, Period = 4, CalendarDate = "2021-04-01", WeekOfYear = 13, DayOfYear = 61, WeekOfPeriod = 1 },
            new CalendarDto {  FiscalYear = 2021, CalendarType = "4-5-4", Quarter = 3, Period = 8, CalendarDate = "2021-08-01", WeekOfYear = 24, DayOfYear = 121, WeekOfPeriod = 1 }
        };
        return testDto;
    }

目前，在试图比较这两个集合时，测试没有说它们是不平等的。

Assert.AreEqual failed. Expected:<System.Collections.Generic.List`1[cscentcalendar.infrastructure.DTOs.CalendarDto]>. Actual:<System.Collections.Generic.List`1[cscentcalendar.infrastructure.DTOs.CalendarDto]>. 

不知道我做错了什么。如能提供任何协助，将不胜感激。

我相信我通过使用fluent断言和添加下面的代码行来测试这两个集合来解决这个问题。如果这是不正确的，请告诉我。再次感谢！

    expectedCalendarDto.Should().BeEquivalentTo(act);
