the class MeterFilterTest method maximumAllowableTags.

@Test
void maximumAllowableTags() {
    AtomicInteger n = new AtomicInteger(0);
    MeterFilter filter = MeterFilter.maximumAllowableTags("name", "k", 2, new MeterFilter() {

        @Override
        public MeterFilterReply accept(Meter.Id id) {
            n.incrementAndGet();
            return MeterFilterReply.NEUTRAL;
        }
    });
    Meter.Id id = new Meter.Id("name", Tags.of("k", "1"), null, null, Meter.Type.COUNTER);
    Meter.Id id2 = new Meter.Id("name", Tags.of("k", "2"), null, null, Meter.Type.COUNTER);
    Meter.Id id3 = new Meter.Id("name", Tags.of("k", "3"), null, null, Meter.Type.COUNTER);
    filter.accept(id);
    filter.accept(id);
    filter.accept(id2);
    filter.accept(id);
    filter.accept(id3);
    assertThat(n.get()).isEqualTo(1);
}
