The method post(string) is undefined for controller test

Problem :

I came across this common exception when i was using mocks for unit testing spring application.

Exception I Encountered Was :

the method post(string) is undefined for controller test

################################################################################################### ################

Solution :

When unit testing your spring application with mocks you need to make sure that you are using the necessary static imports in your code.
See below for the list of static imports to use.

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

Once i had the static imports in place it resolved the exception. Hope this helps resolve your exception, Happy Coding.
