Overriding beans in Integration tests

Question

For my Spring-Boot app I provide a RestTemplate though a @Configuration file so I can add sensible defaults(ex Timeouts). For my integration tests I would like to mock the R

Answer 1

With @Primary annotation, Bean overriding works with Spring Boot 1.5.X but fails with Spring Boot 2.1.X it throw error:

Invalid bean definition with name 'testBean' defined in sample..ConfigTest$SpringConfig:.. 
There is already .. defined in class path resource [TestConfig.class]] bound

Please add below properties= which will instruct Spring explicitly to allow overriding, it is self explainatory.

@SpringBootTest(properties = ["spring.main.allow-bean-definition-overriding=true"])
