If you would like to vote for inclusion of support for AssertJ assertions with MockMvc, please see the related Spring JIRA issue: SPR-16637.

There has recently been an issue raised on the Spring Boot project to discuss adding support for AssertJ assertions with MockMvc, it might be worth keeping an eye on it. You can view the issue here: https://github.com/spring-projects/spring-boot/issues/5729

It looks like the initial concept created by Phil Webb involves wrapping the MockMvc to provide support for AssertJ assertions.

I've put together a library that offers AssertJ assertions for MockMvc but also for ResponseEntity (returned by TestRestTemplate): https://github.com/ngeor/yak4j-spring-test-utils
