Question

我在Massive类上创建了一个Find方法。问题是我刚刚意识到它总是返回true，因为结果永远不会为空。这是我的代码：

    public dynamic Find(string email)
    {
        dynamic result = new ExpandoObject();
        dynamic experience = new ExpandoObject();
        result.Success = false;
        experience = this.Query(@"SELECT we.* FROM WorkExperience we
            LEFT JOIN Members m ON m.Id = we.MemberId 
            WHERE m.Email = @0", email);
        if (experience != null)
        {
            result.Experience = experience;
            result.Success = true;
        }
        return result;
    }

在这种情况下，体验永远不会为null所以result.Success总是返回false。如何测试this.Query（）是否返回记录？

Answer 1

我这样做是为了测试我的查询是否带回记录。

控制器：

 public ActionResult Index() {
        _logger.LogInfo("In home");
        //var data = _tricksTable.All(orderBy: "DateCreated");
        dynamic viewModel = new ExpandoObject();
        var data = _tricksTable.Query("SELECT TOP(10) * FROM Tricks ORDER BY DateCreated DESC");
        viewModel.TenTricksNewestFirst = data;

        var data2 = _tricksTable.Query("SELECT TOP(10) * FROM Tricks ORDER BY Votes DESC");
        viewModel.TenTricksMostPopularFirst = data2;
        return View(viewModel);
    }

并测试：

[Test]
    public void a_user_should_be_able_to_view_10_newest_tricks_in_latest_videos_tab() {
        var result = _controller.Index() as ViewResult;
        dynamic viewModelExpando = result.ViewData.Model;
        var queryFromMassiveDynamic = viewModelExpando.TenTricksNewestFirst;

        var i = Enumerable.Count(queryFromMassiveDynamic);
        Assert.AreNotEqual(0, i, "TenTricksNewestFirst returned 0 records");
        Assert.LessOrEqual(i,10, "Ten Tricks Newest First returned more than 10 tricks");
    }

作为未来求职者的参考，这实际上要简单得多。而不是使用DynamicModel的Query方法，调用Scalar方法并确保您选择a）只有一个值，然后测试结果是否为null或b）匹配计数，您可以从中将结果转换为整数并根据返回的数字进行测试。
