I\'m having some issues today with running a simple TestKit test in Intellij. The tests are for Scala code (I have the Scala plug-in for Intellij) and are based on Ray Roes
I met this issue when I used Gatling
I fix it by replacing gatling-classes to test-classes on File -> Project Structure -> Modules -> Module Name -> Paths -> Test output path
gatling-classes
test-classes
