Automated testing

[dkfellows]

Building on #11 and #12, it's a very good idea to have your Github Action automation run your tests on every commit. Doing that automatically is great because then you don't forget just because you happened to have bad day for some reason.

Here's an example section (from one of my projects) of build.yml to enable that:

    - name: Build Project
      uses: threeal/[email protected]
      with:
        run-build: true
        run-test: true
        test-args: -C Debug
      env:
        CMAKE_BUILD_TYPE: Release
      timeout-minutes: 10

Specifically, adding run-test: true is the key part.
