test suite fails `hypothesis` is in the environment (a test dependency of pytest)

この失敗は、tox.ini のテスト設定のもとで testing/test_xfail_behavior.py に再現されます。まず pytest と Hypothesis プラグインをインストールした状態で xfail テストを実行し、その後、報告されたプラグインと出力の不一致を調査してください。その環境で、期待される xfail と xpass の動作を失うことなくテストスイートがパスすれば完了です。

Hi,

I'm trying to update this package to 1.3.0 on GNU Guix, but I'm encountering the following test failures:
