CodeCoverage.exe and vstest.console.exe does not generate covered lines

Question

I have a unit test project, which only has one (1) test written against WebAPI project. When I run test coverage under Visual Studio 2015 Enterprise, it generates report with 9 lines covered. Which is correct.

However, when I run my coverage analysis with "vstest.console.exe" run analysis with "CodeCoverage.exe" which is under "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Team Tools\Dynamic Code Coverage Tools\CodeCoverage.exe", these generates .coverage and .coveragexml file with correct names, and when I open this file with VS 2015, it shows 0 lines of code covered.

I am targeting my same unit test .dll while I am running collect and analyze commands.

I am willing to use my reports agains sonarqube.

Am I missing something here?

Are you sure you can just run the CodeCoverage.exe directly? According to this MSDN page you should run it through visual studio's UI, or you can run it like this: vstest.console.exe MyTestAssembly.dll /EnableCodeCoverage, meaning you use vstest.console.exe and not CodeCoverage.exe. — Quantic
@Quantic yes, I am following steps at stackoverflow.com/a/31810755/929902 — Teoman shipahi
@Quantic correction, you are right, I was actually using vstest.console.exe. But, result is same. Edited my question. — Teoman shipahi

You can add "/Diag:" parameter when you run VSTest.Console.exe to show detailed log. One problem I have encountered that, if I run VSTest.Console.exe on my local, it works; but when I run VSTest.Console.exe in Jenkins, it has no coverage data. Here is an solution for running VSTest.Console.exe in Jenkins: VSTest.console.exe when run under Jenkins generate empty .coverage file.

I can't find any other useful information why running as a local account works in Jenkins. But when I use OpenCover, which may use similar way how to get coverage data with VSTest.Console. OpenCover requires "register profiler" in order to get coverage data. (https://github.com/OpenCover/opencover/blob/master/main/OpenCover.Documentation/Usage.rtf, search "register")

So, I think your issue may be caused by permission. Just have a try to run it in adminstrator. :)
