Setting up the Controller to test

This step is very similar to the previous flow. We want to test BasicViewController. We instantiate MockMvc using BasicViewController. We also configure a simple view resolver:

    public class BasicViewControllerTest { 
      private MockMvc mockMvc; 
      @Before 
      public void setup() { 
        this.mockMvc = MockMvcBuilders.standaloneSetup 
        (new BasicViewController()) 
        .setViewResolvers(viewResolver()).build(); 
       } 
      private ViewResolver viewResolver() { 
        InternalResourceViewResolver viewResolver =  
        new InternalResourceViewResolver(); 
        viewResolver.setViewClass(JstlView.class); 
        viewResolver.setPrefix("/WEB-INF/jsp/"); 
        viewResolver.setSuffix(".jsp"); 
       return viewResolver; 
      } 
    }
