DevOps與後端系統建置必修技能！ 鑒於前後端分離與微服務架構的興起，伺服器端需要提供API供用戶端存取。傳統的SOAP協定是以複雜的XML作為傳送媒介，已經逐漸被使用輕量化JSON傳送資訊的REST API取代，成為開發與建置API的主流。 除此之外，API的開發和上線應用，效率與品質應該兼顧。透過DevOps流程結合開發、測試、營運，可以更快地將新增或修正的功能發佈給使用者；在這樣的環節中，自動化測試至關重要。 本書第一部分介紹Java的單元測試框架如JUnit5、Mockito、PowerMock，並探討如何提升程式的可測試性。 第二部分先介紹REST API的概念與背景。在使用Spring Boot建置初版REST API後，逐章示範API的例外處理、Swagger文件說明、版本控制、分頁與排序、與套用HATEOAS等。 最後結合Spring Test模組對REST API進行單元測試、整合測試、與端對端測試，以期產出符合企業品質與效率的REST API。
