Code coverage results

It would be great if we could get code coverage analysis as part of running the unit tests. I think this could be done now as part of a post build script that then pushes the code coverage information into the build log, but that isn't as nice as having it be an integrated part of the build process where the results are surfaced as an additional tab next to the Tests tab.

    What tool would you recommend for running code coverage analysis?

    Personally, I'd love to see the ability to use the Microsoft code coverage tools but I don't know if (or how well) it works with test frameworks other than MSTest. The only other tool I know of is NCover, of which I have never been a big fan.

    Another option for this would be to give us a way to add new "tabs" ourselves. TeamCity has this option, where you basically configure it so that a "tab" points to a log file and then the contents of that log file appear as the tab contents. This would allow us to run any code coverage tool we want (or really any tool) through scripts and have the output log appear as build results.

    I'm not sure if you use vstest.console.exe to run just MSTest based unit tests, but it looks like you can use the /Enablecodecoverage switch on it to capture code coverage analysis results.

    dotCover is a great tool from JetBrains and it's available out of the box with TeamCity. It could be a great thing to have in AppVeyor but it's not free.

    I'd look into vstest.console code coverage results and OpenCover as the most available options.

    DotCover is very popular, but it's commercial product with strict licensing competitor. I'm just wondering if I ask them about hosting DotCover on AppVeyor :)

    Haven't looked into that yet, sorry. It doesn't sound trivial and we are trying to prioritize. There were Azure-related issues with build workers provisioning. It's resolved by now, but we want to make sure that part works well. Another thing we are going to deal with is deployment improvements.

    I am looking into OpenCover. Maybe you want to try that:

    +1 for this request.

    Be wonderful to be able to use DotCover in this way (or even add tabs from any script as Scott describes...)

    DotCover requires license, no?

    DotCover does require a license, but I think they are free for Open Source projects.

    It seems to me to be not too complex to run OpenCover (& ReportGenerator) to do basic code coverage, here are some notes for how I hacked it together:

    Looks great for the start! Additionally, you can write a simple script to push XML test results to "Tests" tab of build. Take a look at this thread for example:

    The API:

    I used the default nunit-console in the script - which means I am seeing
    the results to the "Tests" already (no extra work!)

    Is that what you meant?

    Yeah, exactly. Nice that it worked as is :)

    If you are looking to add OpenCover please feel free to raise a support issue. I am currently trying out apveyor for OpenCover building and I use opencover to gather coverage on opencover tests (dogfooding).

    Since you are probably running as a non-admin then remember to use the -register:user option when running nunit, mstest, xunit etc etc.

    I have been able to integrate OpenCover, ReportGenerator and Coveralls with Appveyor.
    Results are here:
    Download the "log" artifacts and you will be able to see the report results. And on Coveralls:
    Source code is here:
    I am using to do it. All build files are on the root folder.

    Just ask them! :)
    I actually just opened an issue so that they can add Appveyor to their supported build servers:
    Maybe you want to help by commenting there. :)

    Any updates on built in support for code coverage in AppVeyor?

    Would also be interested in such integration. OpenCover + ReportGenerator looks like a good tandem for this

    Is this feature available?
    + 1 for out of the box support in AppVeyor for code coverage at least with MSTests.
    Thanks in advance

    For everyone's information there's also, which works great with appveyor and opencover. It takes a little setup though. I've got it working with nunit and xunit. See my appveyor.xml in wikibus/JsonLD.Entities and wikibus/Argolis github repos
