Play Framework 2 running JUnit tests in Intellij IDEA

I use Play Framework 2.0.4 and Java + IntelliJ IDEA.

Try to launch tests from IDEA, and having error like this:

Class not found: "models.SoftwareTest"

Here is the test itself.

package models;

    public class SoftwareTest {

        @Test
        public void findById() {
            running(fakeApplication(), new Runnable() {
                @Override
                public void run() {
                    Software software1 = Software.find.byId(1L);
                    assertThat(software1.name).isEqualTo("Soft1");
                    assertThat(software1.description).isEqualTo("Description1");
                }
            });
        }
    }

Anyone?

P.S. I've already cleaned all project/ivy files, having switched from play 2.0.4 to 2.1 RC1 and back.. it does not help. But it was working one day in the past. And I found a lot of records about this in Google, but could not find the answer yet.

Also I've checked out this article (related to Ebean and testing):

But the problem I have now it's different one. But just share this link here, it could help to reproduce the problem.
