Hello.
I wrote small service listening for GPS device messages.
I wrote also ServiceTestCase planning to check that my service returns
correct longitude and latitude when location is changed.
Unfortunately, onLocationChanged is not called not in the service
under the test nor in the test case.
Should it work?
If yes, what's wrong with my test case?
Thanks in advance.
