The convention is to prefix the test file name by i. The tests starting with t are the ones that come from scalac IIRC

trait Foo
class One extends Foo
class Two extends Foo
class Bla extends One
}

class Test(val c: C) {
import c._
def test(f: Foo) = f match { // not exhaustive
case f: One =>
case f: Two =>
case f: Bla => // unreachable case
}
}
