TypeScriptとJestではじめる AWS製サーバーレス REST API のユニットテスト・E2Eテスト #serverlessfukuoka #serverlessdays / Serverless testing using TypeScript and Jest

この発表では、サーバーレスアプリケーションのユニットテストとE2Eテストを書くときの考え方とその手段について述べます。テストについて議論するときは、アプリケーション設計についても述べなければなりません。

発表の中でまず、サーバーレスアプリケーションは、レイヤ・機能別にコードを分類できることを示します。その後、分類しおたコードに対し、Jestでモック化し、テスト対象を抽出してテストするユニットテストを行います。このときモック対象の戦略についても話します。

最後にE2Eテストの有効性と実行方法を述べます。
