Question

My folder structures:

• root
  • .idea folder
  • Other Unrelated projects
  • myplayapp
    • src (the Actual Play! folder)
    • myplayapp.iml
    • app
    • conf
    • logs
    • public
    • …

I’m trying to run/debug my first unit test from within IntelliJ, and getting an error “Cannot read application.conf“. When I debug into Play.readConfiguration(), I see that Play.init() is passed a file pointing at the root folder (it’s “.”, but its absolute path points to root).

I’ve tried passing the argument -Dapplication.path=myplayapp\src, but I don’t think it’s even processed before the error is thrown.

Is there something I can do here? In the meantime, I’ll try creating an IntelliJ project within the myplayapp folder, but that’s a workaround, not a real solution.

What you should do is:

• Launch your application in test mode (with Debug config) from IntelliJ
• Put the breakpoints in your tests
• Go to http://localhost:9000/@tests and select the tests from your module
• Run the tests

That should work, barring any other unrelated issues.
