Examples of ThreadedTestHelper

org.apache.cayenne.unit.util.ThreadedTestHelper
Helper class allowing unit tests to wait till a code in question executes in a separate thread. There is still some element of uncertainty remains, since this implementation simply tries to give other threads enough time to execute, instead of watching for threads activity.
Note that result sampling is done every 300 ms., so if the test succeeds earlier, test case wouldn't have to wait for the whole time period specified by timeout.

        // check underlying cache
        assertNull(context.getObjectStore().getDataRowCache().getCachedSnapshot(
                altArtist.getObjectId()));


        // check peer artist
        ThreadedTestHelper helper = new ThreadedTestHelper() {


            @Override
            protected void assertResult() throws Exception {
                assertEquals(PersistenceState.NEW, altArtist.getPersistenceState());

        // check if now we can save this object again, and with the original
        // ObjectId
        ObjectId id = altArtist.getObjectId();
