Our tests take quite some time and quite a significant amount is due to coverage (see #9463).

研究方向
The issue asks for ways to speed up coverage during tests. Begin by reading the referenced issue #9463 for context. Then profile the current test suite to identify slow coverage related steps. Investigate alternative coverage tools or configurations (e.g., using pytest cov with parallel execution, or subset coverage). Consider if incremental coverage or caching could help. Report findings and propose a concrete optimization in the issue.
can coverage be made faster somehow? · borgbackup/borg#9470 | Good First Issue
