  1. Using ArchUnit to test your architecture Matt Ho

  2. About me - Hi, I'm Matt 👋 - 松凌科技 Architect

    / R&D - JCConf Speaker - [email protected] - https://github.com/shihyuho

  3. 放⼼, 這不是在講架構

  4. 本節在分享 架構已經在那了 && 該如何確保在持續開發/維運的過程中, 應⽤程式仍 然遵循著架構走

  5. https://www.archunit.org/

  6. ArchUnit Overview - 是⼀個測試套件, 整合了 JUnit 4, JUnit 5 等

    - 良好的 Fluent API - 容易延伸擴充 - Apache-2.0 license

  7. 運作過程

  8. 起⼿式 決定從哪邊開始匯入 bytecodes

  9. 起⼿式 定義 Rules

  10. 起⼿式 ArchUnit 執⾏得到結果

  11. 起⼿式 - Rule Pattern ArchRuleDefinition.GIVEN_OBJECTS .that(). PREDICATE .should(). CONDITION

  12. Controller 命名必須以 ‘Controller’ 結尾 Class Naming

  13. Controller 命名必須以 ‘Controller’ 結尾 Class Naming

  14. Class Naming Controller 命名必須以 ‘Controller’ 結尾

  15. Class Naming Data Access 命名必須以 ‘Dao’ 結尾

  16. Class Naming Data Access 命名必須以 ‘Dao’ 結尾

  22. Layered Architectures.layeredArchitecture() .layer(). PREDICATE .whereLayer(). CONDITION

  23. Layered 定義 3 層 layer 定義依賴關係

  24. General

  25. Freeze - 套⽤在舊的系統中, 超多條違規改不動 ;-(

  26. Freeze - 套⽤在舊的系統中, 超多條違規改不動 ;-( - 好吧, 那就現在開始的程式才檢查 :-)

  27. Freeze - 套⽤在舊的系統中, 超多條違規改不動 ;-( - 好吧, 那就現在開始的程式才檢查 :-) FreezingArchRule.freeze(
