当试图用webgrid对控制器进行单元测试时,HttpContext为空
本文关键字:单元测试 为空 HttpContext 控制器 webgrid | 更新日期: 2023-09-27 18:09:17
我正试图用webgrid对控制器进行单元测试
var grid = new WebGrid(ajaxUpdateContainerId: "container-grid",ajaxUpdateCallback: "setArrows", canSort: true);
我总是得到这个错误
System.ArgumentNullException: Value cannot be null.
Parameter name: httpContext
这是我的Test方法
var mockContext = CreateMockContext();
UserController target = new UserController();
target.ControllerContext = new ControllerContext();
target.ControllerContext.HttpContext = mockContext.Http.Object;
Nullable<int> page = new Nullable<int>();
string sort = "CreatedDate";
string sortdir = "ASC";
ActionResult actual;
actual = target.Payments(page, sort, sortdir);
Assert.IsNotNull(actual);
这是我的CreateMockContext方法
public UnitTestBase CreateMockContext()
{
this.RoutingRequestContext = new Mock<RequestContext>(MockBehavior.Loose);
this.ActionExecuting = new Mock<ActionExecutingContext>(MockBehavior.Loose);
this.Http = new Mock<HttpContextBase>(MockBehavior.Loose);
this.Server = new Mock<HttpServerUtilityBase>(MockBehavior.Loose);
this.Response = new Mock<HttpResponseBase>(MockBehavior.Loose);
this.Request = new Mock<HttpRequestBase>(MockBehavior.Loose);
this.Session = new Mock<HttpSessionStateBase>(MockBehavior.Loose);
this.Cookies = new HttpCookieCollection();
this.RoutingRequestContext.SetupGet(c => c.HttpContext).Returns(this.Http.Object);
this.ActionExecuting.SetupGet(c => c.HttpContext).Returns(this.Http.Object);
this.Http.SetupGet(c => c.Request).Returns(this.Request.Object);
this.Http.SetupGet(c => c.Response).Returns(this.Response.Object);
this.Http.SetupGet(c => c.Server).Returns(this.Server.Object);
this.Http.SetupGet(c => c.Session).Returns(this.Session.Object);
this.Http.SetupGet(p => p.User.Identity.Name).Returns("admin");
this.Http.SetupGet(p => p.Request.IsAuthenticated).Returns(true);
this.Request.Setup(c => c.Cookies).Returns(Cookies);
return this;
}
我可以测试其他控制器很好。只有带有webgrid的控制器才会失败。请帮助。
您在控制器中实例化WebGrid
的原因是什么?根据这篇MSDN文章,您似乎可以将WebGrid
实例化移动到控制器的视图中,并从其逻辑中删除该依赖项。这当然会使编写单元测试更容易。
