Examples with ServiceEvent org.osgi.framework.ServiceEvent used on opensource projects

Example 1 with ServiceEvent

use of org.osgi.framework.ServiceEvent in project sling by apache.

the class LogSupportTest method testServiceEvent.

@Test
public void testServiceEvent() throws Exception {
    final Map<String, Object> props = new HashMap<String, Object>();
    props.put(Constants.OBJECTCLASS, new String[] { "some.class.Name" });
    props.put(Constants.SERVICE_ID, 999L);
    ServiceReference sr = Mockito.mock(ServiceReference.class);
    Mockito.when(sr.getBundle()).thenReturn(bundle);
    Mockito.when(sr.getProperty(Mockito.anyString())).then(new Answer<Object>() {

        public Object answer(InvocationOnMock invocation) throws Throwable {
            return props.get(invocation.getArguments()[0]);
        }
    });
    Mockito.when(sr.getPropertyKeys()).thenReturn(props.keySet().toArray(new String[] {}));
    ServiceEvent se = new ServiceEvent(ServiceEvent.REGISTERED, sr);
    logSupport.serviceChanged(se);
    Mockito.verify(testLogger).info("Service [999, [some.class.Name]] ServiceEvent REGISTERED", (Throwable) null);
}
