use of com.hazelcast.internal.nio.Connection in project hazelcast by hazelcast.

the class MemberReconnectionStressTest method test.

@Test
public void test() {

        The test will start 2 thread:
        - one will submit short batch jobs, serially, after joining the previous job
        - the other will keep dropping the member-to-member connection.

        The small jobs will often fail due to the reconnection, we check
        that the job completes in a limited time. We drop the connection
        at a rate lower than the normal job duration so there's
        typically at most 1 restart per job. We assert that the jobs
        eventually successfully complete.
