Unable to run JUnit test in IntelliJ

I wanted to start project using TDD. Created the test directory and later changed it to package that is integrated with src direcotry. In both cases I get the same error:

Class not found: "tests.objectsTest"

I tried different techniques of importing JUnit jar and none solved problem. Also I tried to rename my test class but it gives no solutons whatsoever.

It seems that IntelliJ or JUnit changes name of the test class. Shouldn't it be "objectsTest.tests"?

I am using JUnit version 4.12 and latest IntelliJ EAP.
