I use SBT plugin for IntelliJ and I have created a scala project with the following build settings: Build.scala:
lazy val root =
Project("root", file("."))
.configs( IntegrationTest )
.settings( Defaults.itSettings : _*)
build.sbt:
<setting some parameters>
libraryDependencies += "org.scalatest" % "scala-test_2.10" % "1.0.8" % "test,it"
Now I end up with src/main, src/test and src/it in my project structure. I now can run compile, test and it:test from both SBT console in IntelliJ and in SBT repl. So all is great at this point.
The only problem I yet to figure out is how to debug integration tests. I have added a scalatest configuration that runs test:compile before launch and this gets me going with unit test debug. I try to create a new Debug configuration for integration tests, but can't figure out how to point it to src/it to find the tests. I tried to debug a specific test by changing "Test kind" to class and pointing to a specific test class, but keep getting the following exception:
Unable to load a Suite class. This could be due to an error in your runpath. Missing class: it.AddPersonSpec
java.lang.ClassNotFoundException: it.AddPersonSpec

When I look into "Project Structure" -> "Modules", I see that src/it/scala is under "Test source folders" category. Not sure where else to look now ...
Update: I had an sbt configuration problem. I used project name "root" in Build.scala and other name in build.sbt. This created two module configurations for IntelliJ. I fixed that and now I can't reconcile IntelliJ and sbt settings for my only module.
The effect that I see now is that after I run gen-idea from sbt console and reload the project, my integration test looks fine for a little while (while sbt is being updated). I can even get to a definition of 'And' method defined in Scalatest. After a few seconds, however, it 'looses' a reference to scalatest lib (when sbt is done updating). When I go to "Project Structure" -> "Modules", I don't see src/it/scala anywhere. If I add it manually to test source IntelliJ can resolve scalatest again. After I run gen-idea it disappears. Rinse and repeat.
Note that remote debugger solution proposed by Eugene does not work for me. I run sbt as a server and attach IntelliJ, but when I run it:test it does not stop on breakpoint. I think it is because integration test source is not considered to be a part of source/test by IntelliJ.
If I first add src/it/scala in project settings and then try to use remote debugger before running gen-idea, then SBT crashes with OutOfMemory. So I'm completely stumped at this point...
Any thoughts are highly appreciated.
