Spring Boot Unit Test a module not detecting an autowired component

Provide your test with @ContextConfiguration(classes = ClassToAutowire.class), then your context will be provided with that class. @SpringBootTest annotation is used in Integration Tests to load full context. With @ContextConfiguration annotation you are able to load only part of context.

@SpringBootTest is used for integration tests that's mean integrating different layers of the application. This is why it loads the whole context.

If you want to unit test only controllers, use @WebMvcTest and mock all the other layers that you need.

For full unit tests of all the layers with working examples see: Testing in Spring
