Q:

JUnit Mockito SpringMVC 404

while testing spring mvc controller with JUnit and Mockito
got this line 
WARNING: No mapping found for HTTP request with URI [application] in DispatcherServlet with name ''
Does that mean that DispatcherServlet was not loaded? How to configure it properly? Thanks

the problem was in the line
mockMvc.perform(get("application")).andExpect(status().isOk());

"application" should be changed to "/application" and everything will work
