How to run scala tests with junit 4?

Question

I can't run following code with IDEA

@Test
class CompanyURLTest extends Assert {
  @Test
  def test = assert(false);

}

It runs, but J-Unit says that there are not test to run

Answer 1

I generally use ScalaTest in combination with the Junit4 runner so that Maven sees and executes my tests. I like the Spec/FlatSpec/WordSpec semantics for organizing tests. I'm experimenting with the ShouldMatchers but I have used JUnit for so long that asserts just seem a bit more natural to me.

Here's an example:

import org.junit.runner.RunWith
import org.scalatest.junit.JUnitRunner
import org.scalatest.FlatSpec
import org.scalatest.matchers.ShouldMatchers

@RunWith(classOf[JUnitRunner])
class BlogFeedHandlerTest extends FlatSpec with ShouldMatchers with Logging {
    "the thingy" should "do what I expect it to do" in {
        val someValue = false;

        assert(someValue === false)
    }
}
