Examples with Repeat org.neo4j.test.rule.RepeatRule.Repeat used on opensource projects

Example 1 with Repeat

use of org.neo4j.test.rule.RepeatRule.Repeat in project neo4j by neo4j.

the class DynamicTaskExecutorTest method shouldCopeWithConcurrentIncrementOfProcessorsAndShutdown.

@Repeat(times = 10)
@Test
public void shouldCopeWithConcurrentIncrementOfProcessorsAndShutdown() throws Throwable {
    // GIVEN
    TaskExecutor<Void> executor = new DynamicTaskExecutor<>(1, 2, 2, PARK, "test");
    Race race = new Race().withRandomStartDelays();
    race.addContestant(() -> executor.close());
    race.addContestant(() -> executor.processors(1));
    // WHEN
    race.go(10, SECONDS);
// THEN we should be able to do so, there was a recent fix here and before that fix
// shutdown() would hang, that's why we wait for 10 seconds here to cap it if there's an issue.
}
