Just been playing around for the first time with IntelliJ IDEA Community edition, first time I have worked with it so if I\'m missing something, please excuse me.
In my case problem was in pom.
I moved from fulling working application to spring-boot implementation and only imported spring-boot-starter-test in dependency for testing.
I solved by excluding junit part from spring-boot-starter-test and added junit dependency of latest version in separate block.
