Unit tests for web layers involve testing the Controllers--REST and otherwise.
We recommend the following:
- Using Mock MVC for web layers built on Spring MVC
- Jersey Test Framework is a good choice for REST Services built using Jersey and JAX-RS
A quick example of setting up the Mock MVC framework is shown as follows:
@RunWith(SpringRunner.class) @WebMvcTest(TodoController.class) public class TodoControllerTest { @Autowired private MockMvc mvc; @MockBean private TodoService service; //Tests }
Using @WebMvcTest will allow us to use autowire MockMvc and execute web requests. A great feature of @WebMVCTest is that it only instantiates the controller components. All other Spring components are expected to be mocked and can be autowired ...
