Description

Groovy runs a class as a testNG test only if at least one method is annotated with org.testng.annotations.Test. If the @Test annotation is only done at the class level, the class is not recognized as a TestNG test class.

I looked into it and found that org.codehaus.groovy.vmplugin.v5.TestNgUtils.realIsTestNgTest() checks only method level annotations) to determine if a class can be run as a TestNG test class.

Example code:

import org.testng.annotations.Test;

@Test
class GroovyTest {
	void willPass() {
		assert 1 == 1
	}
}

The code above fails with following error:

Caught: groovy.lang.GroovyRuntimeException: This script or class could not be run.
It should either: 
- have a main method, 
- be a JUnit test, TestNG test or extend GroovyTestCase, 
- or implement the Runnable interface.
