Examples with MockClock io.micrometer.core.instrument.MockClock used on opensource projects

Example 6 with MockClock

use of io.micrometer.core.instrument.MockClock in project micrometer by micrometer-metrics.

the class CompositeLongTaskTimerTest method mapIdsToEachLongTaskTimerInComposite.

@Test
void mapIdsToEachLongTaskTimerInComposite() {
    MockClock clock = new MockClock();
    MeterRegistry s1 = new SimpleMeterRegistry(SimpleConfig.DEFAULT, clock);
    LongTaskTimer anotherTimer = s1.more().longTaskTimer("long.task");
    LongTaskTimer.Sample anotherSample = anotherTimer.start();
    clock.add(10, TimeUnit.NANOSECONDS);
    CompositeMeterRegistry registry = new CompositeMeterRegistry(clock);
    registry.add(s1);
    LongTaskTimer longTaskTimer = registry.more().longTaskTimer("long.task");
    LongTaskTimer.Sample sample = longTaskTimer.start();
    clock.add(100, TimeUnit.NANOSECONDS);
    assertThat(anotherSample.stop()).isEqualTo(110);
    // if this fails, the composite is using a timer ID that overlaps with a separate timer in a member
    // of the composite rather than mapping the ID to a separate ID in the composite member.
    assertThat(sample.stop()).isEqualTo(100);
}
