This is not possible when using ScriptRunnerSupport
you may switch to ScriptTestSupport - it is pure Java JUnit and allows to group by package/class name.
But it won’t seek for exported functions in js file. You have to specify them
package com.enonic.guide;
import org.junit.Test;
import com.enonic.xp.testing.ScriptTestSupport;
public class FibonacciTest
extends ScriptTestSupport
{
@Test
public void testSequence4()
{
runFunction( "/lib/fibonacci-test.js", "testSequence4" );;
}
}
