Assert.AreEqual失败。预期：其中（空）取代。实际：<system.web.mvc.viewresult> </system.web.mvc.viewresult>

Question

我正在asp.net mvc3上进行单元测试。当我在默认创建的测试上运行测试方法时：

[TestMethod()]
        public void IndexTest()
        {
            ConferenceController target = new ConferenceController(); // TODO: Initialize to an appropriate value
            ActionResult expected = Index; // TODO: Initialize to an appropriate value
            ActionResult actual;
            actual = target.Index();
            Assert.AreEqual(expected, actual);
            Assert.Inconclusive("Verify the correctness of this test method.");
        } 

[TestMethod()]发生此错误：

  

Assert.AreEqual失败。预期：其中（空）取代。实际：

如何传递断言？

Answer 1

ActionResult expected = Index; // TODO: Initialize to an appropriate value

正如评论所示，您应该将Index变量初始化为适当的值。例如：

[TestMethod]
public void Index()
{
    // Arrange
    HomeController controller = new HomeController();

    // Act
    ViewResult result = controller.Index() as ViewResult;

    // Assert
    Assert.AreEqual("Welcome to ASP.NET MVC!", result.ViewBag.Message);
}
