测试失败时＆QUOT;在解决方案＆QUOT运行所有测试;用来 [英] tests failing when "Run All Test in Solution" is used

问题描述

我试图让单元测试来为我的MVC 4 Web应用程序项目成功运行。

I am trying to get unit tests to run successfully for my MVC 4 Web Application project.

当我单独运行测试类中的所有测试都通过了，当我来到运行解决方案仅2/9合格，我点击调试经过测试，他们全部通过，当我命中再次运行，他们也都所有测试通过。

When I run the tests classes individually all of the tests pass, when I come to run all test in solution only 2/9 pass, I have clicked Debug Checked Tests and they all pass when I the hit run again they also all pass.

这个问题，当我检查项目到TFS也被复制的，我有自己的项目设置连续集成构建，运行测试，失败完全相同的测试。

This problem is also being replicated when I check the project into TFS, I have setup continuous integration they project builds, runs the tests and fails on exactly the same tests.

我得到的回复是错误的 *命名为''A路线已经是路由集合在

The error I'm getting back is *"A route named '' is already in the route collection"

没有任何人有任何想法，为什么这可能发生？

Does anybody have any ideas why this might be happening?

在每个类我有一个[TestInitialize]块，如下图所示：

In each class I have a [TestInitialize] block which is shown below:

[TestInitialize]
public void Setup()
{
    var builder = new TestControllerBuilder();
    controller = new MyController();
    builder.InitializeController(controller);

    RouteConfig.RegisterRoutes(RouteTable.Routes);
}

我曾在班一个类似的错误，当我还没有包括TestControllerBuilder，会不会是这个code未正常运行？

I had a similar error in the classes when I hadn't included the TestControllerBuilder, could it be that this code is not running correctly?

推荐答案

的 RouteTable.Routes 是静态的，因此将只每个AppDomain初始化一次。

RouteTable.Routes is static and therefore will only be initialized once per AppDomain.

所以，每次运行测试时间，你实际上是试图一次又一次重新注册相同的路线。

So every time you run a test, you are in effect trying to re-register the same routes over again.

您可能会更好过移动路线注册成<一个href=\"http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.testtools.unittesting.assemblyinitializeattribute%28v=vs.110%29.aspx\"相对=nofollow> AssemblyInitialize 属性，以便它只会在整个测试运行开始运行一次。

You would probably be better off moving your route registration into an AssemblyInitialize attribute so it will only run once at the beginning of the entire test run.
