持續交付：Why 與 What |

稍後的章節將會介紹，你可以將許多功能性與非功能（跨功能）屬性的斷言
（assertion）編入現代的 Java 組建管道，包括容錯、確認已知的安全漏洞是否存在，以
及基本的性能 / 負載特性（可以幫助你估算成本）。
探索典型的組建管道：What
了解持續交付管道各個核心階段的“What”或目的非常重要，因為一件事情的目標
與原則通常比實作細節重要（例如，你究竟要使用 Jenkins、CircleCI、JUnit 還是
TestNG）。
組建管道的核心階段
圖 1-1 是典型的 Java app 持續交付組建管道。CD 程序的第一個步驟是持續整合（CI）。
在這個步驟中，開發者將桌機內，已寫好的程式碼持續提交（整合）到一個共用的版本
控制存放區，它會被自動組建與包裝成工件（artifact）。接著，CI 產生的工件會進入一
系列的自動驗收與系統品質屬性驗證階段，完成後，再在越來越像生產環境的環境中進
行手動用戶驗收測試與晉升。
組建管道的主要目的，是證明你對程式碼或組態做的任何修改所產生的結果都是可放入
生產環境的。你提出的修改可能會在管道的任何一個階段失敗，這項修改可能會被拒
絕，不會被標記成可以部署至生產環境。每一個通過驗證步驟的工件都可以部署至生產
環境。我們在這個管道中收集技術與商業遙測數據，用來建立正面的回饋迴圈。
