C# 使用MSTestV2框架c进行单元测试#

如何对这两个进行单元测试：返回Ok（类别）和异常返回状态（500，“此时无法加载类别”）

我的CategoryController包含：

 [HttpGet]
    public ActionResult<IEnumerable<Category>> Get()
    {
        try
        {
            var categories = _restaurantDb.Categories;

            return Ok(categories);
        }
        catch (Exception)
        {
            return StatusCode(500, "Categories could not be loaded at this moment");
        }
    }

我的尝试，不确定我是否接近，它给了我错误，如下所示

       [TestMethod()]
    public void GetCategoryTest()
    {
        CategoryController controller = new(_restaurantDb);
        var expectedcategories = _restaurantDb.Categories;

        var actualcategories = controller.Get();


        Assert.AreEqual(expectedcategories, actualcategories);
        tried this also 
        CollectionAssert.AreEquivalent(expectedcategories, actualcategories).
        
    }

错误消息： Assert.AreEqual失败。预期：

. 实际：。

您无法比较这样的对象，这只是检查它们是否引用了相同的实例。因此，即使所有字段都相同，它们也不会相等。您需要逐个字段进行比较。

       [TestMethod()]
    public void GetCategoryTest()
    {
        CategoryController controller = new(_restaurantDb);
        var expectedcategories = _restaurantDb.Categories;

        var actualcategories = controller.Get();


        Assert.AreEqual(expectedcategories, actualcategories);
        tried this also 
        CollectionAssert.AreEquivalent(expectedcategories, actualcategories).
        
    }
