JUnit5で＠Autowiredが使えんかった件

Last updated at Posted at 2018-04-08

Spring Boot + JUnit5 環境で、テストクラスで＠Autowiredが動作しないためか変数にインスタンスが生成されずに、NullPointerExceptionが発生。

JUnit5で、Spring Bootを動かす設定がJUnit4とは異なることが判明。

migrate from JUnit 4 to JUnit 5 you can replace 
@RunWith(SpringRunner.class) with @ExtendWith(SpringExtension.class).

参考になるページにたどり着くまで、結構時間かかったです。
