Using jBehave with Mockito gives null pointer exception

Question

Using jBehave with Mockito gives null pointer exception

Console Output: Example: {ename=Tom Brown, id=1, dept=Dept 1} Given a new Employee record When the Employee name is Tom Brown When the Employee id is 1 When the Employee dept is Dept 1 When the method is POST Then the returned values should match (FAILED) (java.lang.NullPointerException: Cannot invoke "org.springframework.test.web.servlet.MockMvc.perform(org.springframework.test.web.servlet.RequestBuilder)" because "this.mockMvc" is null)

Code in GitHub as Maven Project

EmployeeControllerTest.java

}
@Override
