Test failed on a Resource server when using Spring WebMvc RouterFunction

[hantsy]

I created a Resource server example project using Spring WebMvc RouterFunction and Auth0 IDP.

https://github.com/hantsy/spring-webmvc-auth0-sample

When adding tests, I followed the Spring Security Samples.

I tried to use @MockMvc to test the functionality but failed. The @MockMvc can not recognize RouterFunction bean and the new Spring Security Servlet SecurityFilterChain.

• https://github.com/hantsy/spring-webmvc-auth0-sample/blob/master/src/main/java/com/example/demo/config/WebConfig.java#L17
• https://github.com/hantsy/spring-webmvc-auth0-sample/blob/master/src/main/java/com/example/demo/config/SecurityConfig.java#L31

Then I created a MockMvc from WebApplicationContext, check https://github.com/hantsy/spring-webmvc-auth0-sample/blob/master/src/test/java/com/example/demo/ApplicationTests.java, but failed due to an exception.

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException: Cannot invoke "org.springframework.test.web.servlet.DefaultMvcResult.setHandler(Object)" because "mvcResult" is null

Thanks for getting in touch, but this does not appear to be a problem with the code in this repository as it is working. I think this question is better suited for StackOverflow which I and the rest of the security team monitors
