✅ What's done
Expo SDK 48アップグレードの対応で、
App.test.tsxを実行すると以下のエラーが発生jest/__mocks__配下のモックファイルは、モックしているライブラリなどがimport、requireされたときに読み込まれます。テスト対象のコンポーネントの内部で、条件によって
requireするライブラリを切り替えている箇所があり、それが原因でこのエラーが発生したと思われます。そのため、
jest/__mocks__配下のモックファイルでモックをクリアするのをやめて、jest.config.jsのclearMocksを有効化する方法で、テスト実施前にモックをクリアします。jest.config.jsのclearMocksをtrueに設定beforeEachやbeforeAllでモックをクリアしていた箇所を削除git grep mockCleargit grep clearAllMocksOther (messages to reviewers, concerns, etc.)
