Ilya's suggestions,
"
for TrashPurgeScheduleHandler and MirrorSnapshotScheduleHandler tests, instead of just checking that both pre- and post-blocklisting schedules show up, it would be good to test that both pre- and post-blocklisting scheduled work actually gets done. For trash purge scheduler, I would suggest creating two pools with an image trashed in each, adding a short (1-2m) schedule for one pool before blocklisting and for another after blocklisting and asserting that trash purge runs after enough time passes. And similarly for mirror snapshot scheduler: a single pool with two images would do as per-image schedules can be added there.

for TaskHandler test, queue some (let's say 5) flattens on different images before blocklisting and a sixth flatten after blocklisting and assert that all six flattens complete."
