# The following hooks (pytest_configure, pytest_unconfigure) are used

# to modify `cache._default_cache_path` because `clean_parso_cache`
|
|
# has no effect during doctests. Without these hooks, doctests uses
|
|
# user's cache (e.g., ~/.cache/parso/). We should remove this

# workaround once the problem is fixed in py.test.
