Question

I’m having some problems with making my tests insert fake data in my database. I’ve tried a few approaches, without luck. It seems that Global.onStart is not run when running tests within a FakeApplication, although I think I read that it should work.

object TestGlobal extends GlobalSettings {
  val config = Map("global" -> "controllers.TestGlobal")

  override def onStart(app: play.api.Application) = {
    // load the data ... 
  }
}

And in my test code:

private def fakeApp = FakeApplication(additionalConfiguration = (
  inMemoryDatabase().toSeq +
  TestGlobal.config.toSeq
).toMap, additionalPlugins = Seq("plugin.InsertTestDataPlugin"))

Then I use running(fakeApp) within each test.

The plugin.InsertTestDataPlugin was another attempt, but it didn’t work without defining the plugin in conf/play.plugins — and that is not wanted, as I only want this code in the test scope.

Should any of these work? Have anyone succeeded with similar options?

I chose to solve this in another way:

I made a fixture like this:

def runWithTestDatabase[T](block: => T) {
  val fakeApp = FakeApplication(additionalConfiguration = inMemoryDatabase())

  running(fakeApp) {
    ProjectRepositoryFake.insertTestDataIfEmpty()
    block
  }
}

And then, instead of running(FakeApplication()){ /* ... */}, I do this:

class StuffTest extends FunSpec with ShouldMatchers with CommonFixtures {
  describe("Stuff") {
    it("should be found in the database") {
      runWithTestDatabase {       // <--- *The interesting part of this example*
        findStuff("bar").size must be(1);
      }
    }
  }
}
