Missing PDBs

Hi Guys,

I have an open-source project (https://ci.appveyor.com/project/Deveel/deveeldb) that uses Coveralls.io for publishing the coverage reports for it, but lately I'm experiencing the issue of "Missing PDBs" errors.
It seems in fact that OpenCover application, that I fire on a post-test step, it is not able to find the .pdb files of the project: when I do run the same process on a local machine I don't experience such issue.
OpenCover is a caller toward other applications, producing a report of the run, that can happen only if the target application and components provide debugging information: in my configuration, I'm firing a NUnit runner, that succeeds in its execution.

The solution is set to produce debugging information, and in fact this happens in my local machine, but seems ignored on AppVeyor

    Hi Antonello,

    Can you point me to some of the builds with that error please?

    Privet Feodor,

    You can check this build:

    As you will see in one of the artifacts (coverage.xml), the reason for skipping the coverage is the "Missing PDBs".
    In the console output log it is also indicated.

    As you will see, the coverage analysis is done after the NUnit tests are executed by AppVeyor's runner, and it calls the runner again, but from a PS task.

    PS. A possible improvement I dare to suggest you, is to introduce an option to produce coverage results, when executing NUnit tests ;)

    Have you tried adding dir command to make sure PDB files are there in test assembly bin folder?

    Following your suggestion I've listed the content of the folder where the deveeldb-nunit.dll is and the .pdb files are present.
    Analyzing the coverage.xml file produced by OpenCover I noticed that actually the application covers the shadow-copy of the library: although I specifically indicate the /noshadow argument, it seems it is ignored.

    you can check it out at

    So, is it a tool or something is missing (wrong) on build workers?
