Joel,
Thank you! This is very helpful.
What I notice now is that it works for Test classes that
extend org.scalatest.junit.JUnit3Suite. There are other tests in the
codebase that use a @Test annotation as in the example below. Any idea how
to run those?
import org.junit.{Test, After, Before}
class JsonTest {
@Test
def testJsonEncoding() {
...
Thanks!
Roger
