# Spring Boot JUnit 5 主要為實作JUnit5 實現單元測試，之前用比較多的都是JUnit4，這次會要使用JUnit5主要是因為Spring Boot 2.2.0 以上的版本 JUnit 都改為JUnit5 的版本，藉由此次專案來徹底玩一下單元測試。 以往在測試ＡＰＩ如果有使用Swagger 就可以直接在上面測試，但是如果要做到完整的CI/CD，撰寫單元測試的事情是不可或缺的，但因為很久沒有這樣徹底玩過，確實有很多地方是值得一玩，這邊就作為測試的紀錄～\ 參考一: [前往](https://tw511.com/a/01/31070.html#Spring_BootMockMvc_54)\ 參考二: [前往](https://www.jianshu.com/p/4648fd55830e) ```java // JUnitController.java import com.longxiang.backstage.controller.model.request.InsertMerchantReq;
