Example 1 with SynchronousTestListener

use of org.apache.felix.cm.integration.helper.SynchronousTestListener in project felix by apache.

the class ConfigurationListenerTest method test_sync_listener.

         * received. If the flag is not set, we wait at most 2 seconds for the
         * event to arrive. If the event does not arrive by then, the test is
         * assumed to have failed. This will rather generate false negatives
         * (on slow machines) than false positives.
