OpenCover生成一个空报告 [英] OpenCover generates an empty report

问题描述

我使用 OpenCover 以确定一个简单的C＃项目code覆盖。

I am using OpenCover to determine code coverage for a simple C# project.

虽然我可以看到MSTest的运行单元测试（和成功）生成的报告是空的。

Although I can see MSTest running the unit tests (and succeeding) the generated report is empty.

这是我使用的命令：

opencover.console.exe -register -arch:32 
                      -target:"%VSINSTALLDIR%\Common7\IDE\mstest.exe"
                      -targetargs:"/testcontainer:calculatortest.dll"
                      -filter:+[calculator.dll]* -output:coverage.xml

输出

Microsoft (R) Test Execution Command Line Tool Version 10.0.30319.1

生成的报告的内容：

</CoverageSession>

环保

在code在Windows 7上运行64位，但在32位Visual Studio命令提示符环境中执行。

Environment

The code is running on Windows 7 64-bits but is executed in a 32-bit Visual Studio command prompt environment.

修改我在单元测试的调试版本的目录中运行命令，我添加了OpenCover目录到环境路径。

EDIT I am running the command in the directory with the debug build of the unit tests and I added the OpenCover directory to the environment path.

我搜索了类似的问题，PartCover（因为OpenCover似乎是一种分支），但是找不到匹配的问题，presented解决任何事情。

I searched for similar problems with PartCover (because OpenCover appears to be a sort of branch) but could not find anything that matched the problem and presented a solution.

修改我还测试了更广泛的过滤器 - 筛选：+ [*] * 但这并没有改变任何方式输出。

EDIT I also tested with a broader filter -filter:+[*]* but this did not change the output in any way.

修改我还测试了MSTest的 / noisolation 参数<一href="http://stackoverflow.com/questions/1033012/why-partcover-report-shows-0-when-mstest-runs-successfully-and-all-tests-pass">as这里提及。还没有结果。

EDIT I also tested with the MSTest /noisolation argument as mentioned here. Still no results.

修改我也完全去除过滤器并回落到默认的过滤器进行测试。没有结果。

EDIT I also tested by removing the filter completely and falling back to the default filter. No results.

推荐答案

您应该能够使用-register：用户切换每个用户注册做，即它注册（和注销），而不需要完全管理权限。

You should be able to use the -register:user switch to do per user registration i.e. it registers (and unregisters) without needing full admin rights.
