Visual Studio 2010 does not discover new unit tests
提问by driis
I am writing some unit tests in Visual Studio 2010. I can run all tests by using "Run all Tests in Current Context".
我正在 Visual Studio 2010 中编写一些单元测试。我可以使用“在当前上下文中运行所有测试”来运行所有测试。
However, if I write a new unit test, it does not get picked up by the environment - in other words, I am not able to find it in Test List Editor, by running all tests, or anywhere else. If I unload the project and then reload it; the new test is available to run.
但是，如果我编写了一个新的单元测试，它就不会被环境接收到——换句话说，我无法在测试列表编辑器、运行所有测试或其他任何地方找到它。如果我卸载项目然后重新加载它；新的测试可以运行。
When I am adding a unit test, I simply add a new method to an already existing TestClass and decorating it with [TestMethod] attribute - nothing fancy.
当我添加一个单元测试时，我只是将一个新方法添加到一个已经存在的 TestClass 并用 [TestMethod] 属性装饰它 - 没什么特别的。
What might be causing this behaviour, and how do I make it work ?
什么可能导致这种行为，我该如何使它起作用？

I finally figured out the problem. In Options under Test Tools -> Test Project, there is an option "Disable background discovery of test methods". It was turned on - I do not know how that happened, but removing the checkmark and restarting Visual Studio solved the problem.
我终于想通了问题所在。在测试工具-> 测试项目下的选项中，有一个选项“禁用测试方法的后台发现”。它已打开 - 我不知道这是怎么发生的，但是删除复选标记并重新启动 Visual Studio 解决了问题。

I've had this problem as well when building in debug mode. When I switched it to build in release mode that fixed it for me.
在调试模式下构建时，我也遇到了这个问题。当我将它切换到为我修复它的发布模式时。

I had a similar problem in Visual Studio 2012, however none of the solutions worked. I am developing a 64 bit application and the solution was to choose:-
我在 Visual Studio 2012 中遇到了类似的问题，但是没有一个解决方案有效。我正在开发一个 64 位应用程序，解决方案是选择：-
Test -> Test Settings -> Default Processor Architecture -> X64

I've had this issue and option 2 below fixed it for me.
我遇到了这个问题，下面的选项 2 为我修复了它。
Remove any app.config file (not sure why, but one of the MS forums has a few of these posts with this solution) and
Ensure that within the configuration properties of the solution the project is set to build!!
删除任何 app.config 文件（不知道为什么，但 MS 论坛之一有一些与此解决方案相关的帖子）和
确保在解决方案的配置属性中将项目设置为构建！！
