unit-testing - 构建 ASP.NET Core Web API 单元测试时出错

Question

我正在尝试为我构建的 Web API 创建一个单元测试。我使用 Moq 和 xUnit.net 进行测试。我收到以下错误

CS1929“ISetup<dsf_localContext, ValueTask>”不包含“ReturnsAsync”的定义，并且最佳扩展方法重载“SequenceExtensions.ReturnsAsync(ISetupSequentialResult<Task>, ExtractGroupDto)”需要“ISetupSequentialResult<Task>”类型的接收器

谁能帮我纠正错误，或提供替代代码来解决此问题？

以下是 API 代码：

public class ExtractGroupController : ControllerBase
{
    private readonly dsf_localContext _context;
    private readonly IMapper _mapper;

    public ExtractGroupController(dsf_localContext context, IMapper mapper)
    {
        _context = context;
        _mapper = mapper;
    }

    // GET: api/ExtractGroup/5
    [HttpGet("{id}")]
    public async Task<ActionResult<ExtractGroupDto>> GetExtractGroup(int id)
    {
        var extractGroup = await _context.ExtractGroups.FindAsync(id);

        if (extractGroup == null)
        {
            return NotFound();
        }

        return _mapper.Map<ExtractGroupDto>(extractGroup);
    }}

这是单元测试代码（我按照我自己项目的教程中的步骤进行操作）

public class ExtractGroupControllerTests
{
    private readonly ExtractGroupController _sut;
    private readonly Mock<dsf_localContext> _repoMock = new Mock<dsf_localContext>();
    private readonly Mock<IMapper> _mapperMock = new Mock<IMapper>();

    public ExtractGroupControllerTests()
    {
        _sut = new ExtractGroupController(_repoMock.Object, _mapperMock.Object);
    }
    [Fact]
    public async Task GetExtractGroup()
    {
        //Arrange
        int dataId = 1;
        var extractGroupDto = new ExtractGroupDto
        {
            CreatedBy = "XYZ",
            CreatedOn = DateTime.Now,
            ModifiedBy = "XYZ",
            ModifiedOn = DateTime.Now,
            ExtractGroupId = 1,
            ExtractGroupName = "test",
            ExtractGroupDescription = "test desc",
            ActiveFlag = "1"
        };
        _repoMock.Setup(x => x.ExtractGroups.FindAsync(dataId)).ReturnsAsync(extractGroupDto);
        //Act
        var result = await _sut.GetExtractGroup(dataId);
        //Assert
        Assert.Equal(dataId, result.Value.ExtractGroupId);
    }
}
