Example 1 with Event

use of org.robolectric.util.PerfStatsCollector.Event in project robolectric by robolectric.

the class PerfStatsCollectorTest method shouldMeasureElapsedTimeForEvents.

@Test
public void shouldMeasureElapsedTimeForEvents() throws Exception {
    Event firstEvent = collector.startEvent("first event");
    fakeClock.delay(20);
    firstEvent.finished();
    Collection<Metric> metrics = collector.getMetrics();
    assertThat(metrics).containsExactly(new Metric("first event", 1, 20, true));
}

Example 2 with Event

    assertThat(metrics).containsExactly(new Metric("repeatable event", 3, 60, true));
}

Example 3 with Event

use of org.robolectric.util.PerfStatsCollector.Event in project robolectric by robolectric.

the class SandboxTestRunner method methodBlock.
