The two dependencies dep1 and dep2 are fetched and downloaded at the same time, leading to nondeterministic output in the test.

Fix this issue by replacing dep1 and dep2 with [..]

Additionally, sometimes the pending request count can be less than the number of queued requests if the requests finish before the resolver restarts.

Fix this issue by replacing the pending request count with [..] unless it's zero, which is stable.

The two dependencies `dep1` and `dep2` are fetched and downloaded at the
same time, leading to nondeterministc output in the test.

Fix this issue by using `unordered()`.

Additionally, sometimes the pending request count can be less than the
number of queued requests if the requests finish before the resolver
restarts.

Fix this issue by replacing the pending request count with [..] unless
it's zero, which is stable.
