If you use @TestFor Grails (2.0) already mock grailsApplication for you, just set your configs, but do not declare the grailsApplication. Doing that overrides the mocked instance.

@TestFor(MyService)
class MyServiceTests {

  @Before
  public void setUp() {
    grailsApplication.config.something = "something"
  }

  @Test
  void testSomething() {
    MyService service = new MyService()
    service.grailsApplication = grailsApplication
    service.doSomething()
  }


}

EDIT:

You declared a String, to add to config you must parse this. See here an example.

Basically you use the ConfigSlurper().parse() to get a ConfigObject, and use grails.config.merge() to add the contents to the config.
