the class WarningsSnapshotTest method mergeNonEmpty2.

@Test

    WarningsSnapshot expected = builder().tombstonesAbort(ImmutableSet.of(HOME), 42).localReadSizeWarning(ImmutableSet.of(VACATION_HOME), 12).build();
    // validate builder to protect against empty = empty passing this test
    assertThat(a.tombstones.aborts.instances).isEqualTo(expected.tombstones.aborts.instances).isEqualTo(ImmutableSet.of(HOME));
