How do you share classes between test configurations using SBT

In case you want to stick with predefined configurations instead of defining new ones, and since both Test and IntegrationTest extend Runtime (one would expect IntegrationTest to extend Test…), you could use the following:

dependencyClasspath in IntegrationTest := (dependencyClasspath in IntegrationTest).value ++ (exportedProducts in Test).value

This should put all the classes you define in Test on the IntegrationTest classpth.

I was just became aware to amuch better solution thanks to @mjhoy:

lazy val DeepIntegrationTest = IntegrationTest.extend(Test)
