This is My Create method In Controller How to unit test it using UnitTest.

using HMS_Presentation.Controllers;
using Microsoft.AspNetCore.Mvc;
using Microsoft.VisualStudio.TestTools.UnitTesting;


//Unit Test code .

namespace HMS_UnitTest
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {

            DonorController Controller = new DonorController();

            ViewResult result = Controller.Create() as ViewResult;

            Assert.AreEqual("",????);


        }
    }
}

这是我的单元测试类代码如何使用我的控制器对象来检查操作并测试它。我应该在断言中写什么？我在互联网上搜索它，但没有找到任何适当的解决方案，请检查下面的代码并告诉我应该在断言中写什么。我正在使用Visual Studio 2017和.NET CORE 2.0并在我的解决方案中添加了单元测试项目。

在ASPNET Core 2.1中引入了一种称为MVC应用程序的功能测试的功能。使用TestServer帮助简化MVC应用程序的内存端到端测试。见下面的例子

using Xunit;

namespace TestingMvc.Tests
{
    public class TestingMvcFunctionalTests : IClassFixture<WebApplicationTestFixture<Startup>>
    {
        public TestingMvcFunctionalTests(WebApplicationTestFixture<Startup> fixture)
        {
            Client = fixture.CreateClient();
        }

        public HttpClient Client { get; }

        [Fact]
        public async Task GetHomePage()
        {
            // Arrange & Act
            var response = await Client.GetAsync("/");

            // Assert
            Assert.Equal(HttpStatusCode.OK, response.StatusCode);
        }
    }
}
