Grails Unit Test Exception java.lang.Exception: No tests found matching grails test target pattern filter

Question

I am just starting to learn Grails testing and I tried to write my first grails test.For this, I created a fresh grails project and created a controller named com.rahulserver.SomeController:

package com.rahulserver

class SomeController {

    def index() { }
    def someAction(){

    }
}

When I created this controller, grails automatically created a com.rahulserver.SomeControllerSpec under test/unit folder. Here is my SomeControllerSpec.groovy:

package com.rahulserver

import grails.test.mixin.TestFor
import spock.lang.Specification

/**
 * See the API for {@link grails.test.mixin.web.ControllerUnitTestMixin} for usage instructions
 */
@TestFor(SomeController)
class SomeControllerSpec extends Specification {

    def setup() {
    }

    def cleanup() {
    }

    void testSomeAction() {
        assert 1==1
    }
}

When I right click this class, and run this test, I get following:

So why is it failing?

EDIT

I am using grails 2.4.3

The unit tests are defined with Spock by default:

void testSomeAction() {
    assert 1==1
}

Should be written as:

void "Test some action"() {
    expect:
      1==1
}

See http://spockframework.github.io/spock/docs/1.0/index.html
