fixture.FeatureSpec / withFixture(OneArgTest) issue

I want to share a Database / Knowledge base, for a suite of test. I want it to be available for any test suite. I am using featureSpec

Following the Documentation, I use fixture.FeatureSpec.

As of now i have defined the following: 

trait InteractionKbFixtureTrait { this: fixture.Suite =>

type FixtureParam = InteractionKB

def withFixture(test: OneArgTest): Unit = {

    val kb = KbFactory.createKb("", "") // create the fixture

    try {

     this.withFixture(test.toNoArgTest(kb)) // "loan" the fixture to the test

    } finally { 

//kb.stop() // clean up the fixture

}

}

}

followed by

class ExampleSpec extends fixture.FeatureSpec with InteractionKbFixtureTrait {


}

I get the following error :

Type overriding method withFixture in trait Suite of type (test: ExampleSpec.this.OneArgTest) org.scalatest.Outcome; method withFixture in trait InteractionKbFixtureTrait of type (test: ExampleSpec.this.OneArgTest) Unit has incompatible type InteractionKbFixtureTrait.scala

Any help ?

Method def withFixture should return type org.scalatest.Outcome, whereas your def withFixture is returning Unit. Error message is saying that quite clearly.

So for fixing it you need to change line:

def withFixture(test: OneArgTest): Unit = {

like so:

def withFixture(test: OneArgTest): org.scalatest.Outcome = {
