代码覆盖率结果定期给出:生成空结果 [英] Code Coverage Results periodically gives: Empty results generated

问题描述

我在VS2012中使用MSTest在几个不同的项目中遇到了一个反复出现的问题，在那儿我的代码覆盖时不时地停止工作(似乎是随机的)，而是给了我:

I've run into a recurring problem with a few different projects using MSTest in VS2012, where every now and then my code coverage stops working (seemingly at random) and instead gives me:

生成的空结果:未检测到二进制文件.确保 运行了测试，加载了所需的二进制文件，具有匹配的符号文件， 并没有通过自定义设置排除.欲获得更多信息 请参见 http://go.microsoft.com/fwlink/?LinkID=253731

Empty results generated: No binaries were instrumented. Make sure the tests ran, required binaries were loaded, had matching symbol files, and were not excluded through custom settings. For more information see http://go.microsoft.com/fwlink/?LinkID=253731

我已经检查了明显的(建议的内容)，但似乎无法弄清楚是什么原因造成的.

I've checked the obvious (what it's suggested) but can't seem to figure out what is causing it.

这是我的运行设置文件:

Here is my runsettings file:

推荐答案

此链接解决了我的问题:

This link solved my issue: Issue with Code Coverage in VS 2012

关闭Visual Studio 2012，找到.suo文件，将其删除(或重命名)，然后重新启动.工作正常.不知道.suo文件中的哪些内容妨碍了正确的覆盖范围分析.

Close Visual Studio 2012, find the .suo file, delete (or rename) it, restart. Worked fine. No idea what is in the .suo file that prevented proper coverage analysis.
