Problem:
- 2 tests in test_upload_skill.py failing intermittently in CI
- Tests passed individually but failed when run after test_parallel_scraping.py
- Tests failed with exit code 2 instead of 0 when running `--help`
Root Cause:
- test_parallel_scraping.py calls `os.chdir(tmpdir)` to create temporary test directories
- These directory changes persisted across test classes
- When upload_skill CLI tests ran subprocess with path 'cli/upload_skill.py',
the relative path was broken because cwd was still in the temp directory
- Result: subprocess couldn't find the script, returned exit code 2
Fix:
- Added setUp/tearDown to all 6 test classes in test_parallel_scraping.py
- setUp saves original cwd with `self.original_cwd = os.getcwd()`
- tearDown restores it with `os.chdir(self.original_cwd)`
- Ensures tests don't pollute working directory state for subsequent tests
Impact:
- All 158 tests now pass consistently
- No more flaky failures in CI
- Test isolation properly maintained
