What is the proper way to have a variable replaced in my after_test script? I tried the following:
 notice my attempt at using a variable: $(configuration):

after_test:
    - packages\OpenCover.4.5.3723\OpenCover.Console.exe -register:user -target:"vstest.console.exe" -targetargs:"""MyProject.UnitTests\bin\$(configuration)\MyProject.UnitTests.dll""" -output:coverage.xml

but i get the following error message:
Error: The test source file "MyProject.UnitTests\bin\$(configuration)\MyProject.UnitTests.dll" provided was not found.

   As there is just a command try this:

   after_test: 
       - packages\OpenCover.4.5.3723\OpenCover.Console.exe -register:user -target:"vstest.console.exe" -targetargs:"MyProject.UnitTests\bin\%configuration%\MyProject.UnitTests.dll" -output:coverage.xml

   Yes it worked. Thank you. The output in the appveyor console shows the %configuration% instead of 'Debug' or 'Release', which is slightly confusing. If you ever have a chance, it would be great to improve the output in the console to display the actual value. Here's an example of the console to illustrate my point:

   Total tests: 40. Passed: 40. Failed: 0. Skipped: 0. 
   Test Run Successful. 
   Test execution time: 5.3747 Seconds 
   packages\OpenCover.4.5.3723\OpenCover.Console.exe -register:user -target:"vstest.console.exe" -targetargs:"""MyProject.UnitTests\bin\%configuration%\MyProject.UnitTests.dll""" -output:coverage.xml
   Executing: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe
   Microsoft (R) Test Execution Command Line Tool Version 12.0.30723.0

   As a follow-up question: when are we supposed to use curly brackets such as {myvariable}? When are we supposed to use the dollar sign and parenthesis such as $(myvariable)? and when are we supposed to use the percent signs (such as %myvariable%)?

   If it is a "shell" command line, such as something starting with - use %myvariable%. if it's PS command, starting with - ps: use "$env:myvariable". In all other places should use $(myvariable). {myvariable} is only used in version format and assembly patching and there only two vars: {biuld} and {version}.

   Is the above info on variable usage specified anywhere in docs? Had to search for this - would be very useful to make easier to find! Thanks :)
