Question

我设置了工作模式单元以及存储库模式，我正在使用mongodb。

public class CourseRepository : ICourseRepository
{
    private IMongoCollection<Course> _dbContext = null;
    public CourseRepository(IMongoCollection<Course> dbContext)
    {
        _dbContext = dbContext;
    }
    public async Task Add(Course entity)
    {
        await _dbContext.InsertOneAsync(entity);
    }
}

在使用moq编写单元测试用例时，我编写了代码

[TestMethod]
public async Task TestMethod2()
{
       var c = new Mock<ICourseRepository>();
       c.Setup(x => x.Add(new Course { CourseName = "asfd", CourseId = 2, CourseStatus = "Active", CourseStartDate = System.DateTime.Now, CourseEndDate = System.DateTime.Now, CourseEntryDate = System.DateTime.Now })).Verifiable();
       c.Object.Add(new Course { CourseName = "asfd", CourseId = 2, CourseStatus = "Active", CourseStartDate = System.DateTime.Now, CourseEndDate = System.DateTime.Now, CourseEntryDate = System.DateTime.Now });
       c.VerifyAll();
}

我收到以下错误：

Result Message: 
Test method mvc4test.Tests.UnitTest1.TestMethod2 threw exception: 
Moq.MockVerificationException: The following setups were not matched:
ICourseRepository x => x.Add()
Result StackTrace:

任何人都可以帮助我如何测试一个异步，任务和等待的方法。

经过R＆amp; D的批发后，我发现我在设置中使用了两个课程实体一个实例，而在调用方法时使用了一个实例，但应该这样做：

[TestMethod]
        public async Task TestMethod2()
        {
            var c = new Mock<ICourseRepository>();
            Course a = new Course { CourseId = 1 };
            c.Setup(x => x.Add(a)).Verifiable();
            c.Object.Add(a);
            c.VerifyAll();
        }

mvc4 mock设置等待操作
