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来验证我的 API 处理程序是否正确地对集合进行了排序。如您所见，它是模拟数据，我故意乱序创建测试数据以测试 OrderBy 功能。一旦处理程序 returns DTO 集合，我想验证“act”集合与我的“expectedDTO”集合的顺序相同。这是代码：

    [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，在尝试比较这两个集合时，测试失败表明它们不相等。

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

不确定我做错了什么。如有任何帮助，我们将不胜感激。

我相信我通过使用流畅的断言并添加以下代码行来测试这两个集合来解决问题。让我知道这是否不正确。再次感谢！

    expectedCalendarDto.Should().BeEquivalentTo(act);
