放⼼, 這不是在講架構
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
https://www.archunit.org/
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
運作過程
起⼿式 決定從哪邊開始匯入 bytecodes
起⼿式 定義 Rules
起⼿式 ArchUnit 執⾏得到結果
起⼿式 - Rule Pattern ArchRuleDefinition.GIVEN_OBJECTS .that(). PREDICATE .should(). CONDITION
