单元测试中的重定向

Question

如何对 MVC 重定向进行单元测试？

public ActionResult Create(Product product)
{

    _productTask.Save(product);

    return RedirectToAction("Index",new {id = product.Id});

}

public ActionResult Index(int id)
{

    return View();
}

这里我使用了单元测试语句

 var result = controller.CreateGroup(group) as RedirectToRouteResult;
    //// Assert 
    Assert.That(result, Is.Not.Null);

但失败结果返回空值 谁能帮帮我

Answer 1

// Arrange
var product = new Product(){Id=1};

// Act
var result = controller.Create(product);

// Assert
result.AssertActionRedirect()
                .ToController("thisControllerName")
                .ToAction("Index");
