How would I know if appvayer is parsing my yaml file?

If you never seen Meson before then set down and take a look:

Quick question.
I started integrating ci/cd best practices to my Meson projects 
and I was wondering how would I know if AppVayer is parsing my 
yaml file? I know I got a failed build because it was set to 
MSBuild by default. But after I set the value to script, how 
would I know it's doing its work and not just spinning it wheels.
