如何对测试的ASP.NET MVC行动过滤器？ [英] How-to test action filters in ASP.NET MVC?

问题描述

需要对此的指针。发现这和<一个href=\"http://blog.geniar.com/index.php/2009/05/aspnet-mvc-testing-a-custom-authorize-filters/\">this,但我至今仍一片迷茫。

Need some pointers for this. Found this and this, but I'm still kind a confused.

我只想嘲笑ActionExecutedContext，通过它，让过滤工作了一下，检查结果。

I just want to mock ActionExecutedContext, pass it, let filter to work a bit and check result.

任何帮助吗？

过滤器的源代码，你可以找到<一个href=\"http://stackoverflow.com/questions/1052394/asp-net-mvc-how-to-implement-link-which-returns-to-$p$pvious-page\">here

（它改了一下，但是这不是目前的点）。

Source of filter you can find here
(it's changed a bit, but that's not a point at the moment).

所以 - 我想单元测试，即RememberUrl过滤器是足够聪明，保存当前URL的会话。

So - i want unit test, that RememberUrl filter is smart enough to save current URL in session.

推荐答案

1）嘲讽Request.Url在ActionExecutedContext：

1) Mocking Request.Url in ActionExecutedContext:

var request = new Mock<HttpRequestBase>();
request.SetupGet(r => r.HttpMethod).Returns("GET");
request.SetupGet(r => r.Url).Returns(new Uri("http://somesite/action"));

var httpContext = new Mock<HttpContextBase>();
httpContext.SetupGet(c => c.Request).Returns(request.Object);

var actionExecutedContext = new Mock<ActionExecutedContext>();
actionExecutedContext.SetupGet(c => c.HttpContext).Returns(httpContext.Object);

2）假设你在你的RememberUrlAttribute的公共构造注入会话包装。

2) Suppose you are injecting session wrapper in your RememberUrlAttribute's public constructor.

var rememberUrl = new RememberUrlAttribute(yourSessionWrapper);

rememberUrl.OnActionExecuted(actionExecutedContext.Object);

// Then check what is in your SessionWrapper
