Java testing the web layer without authentication spring

In a Spring web application, you can use the WebMvcTest annotation to write and run tests for the web layer without the need for authentication. The WebMvcTest annotation is used to configure a MockMvc instance and inject a subset of the Spring application context, specifically the web layer components, such as controllers, filters, and view resolvers.

Here's an example of how to use the WebMvcTest annotation to write a test for a Spring web application without authentication:

@WebMvcTest(controllers = MyController.class)
class MyControllerTest {

    @Autowired
    private MockMvc mvc;

    @Test
    void testGet() throws Exception {
        mvc.perform(get("/path"))
                .andExpect(status().isOk())
                .andExpect(content().string("expected response"));
    }
}

In this example, the WebMvcTest annotation is used to configure a MockMvc instance for testing the MyController controller. The testGet method uses the mvc object to simulate a GET request to the /path URL and verifies that the response has a status code of 200 (OK) and the expected response body.

You can find more information about the WebMvcTest annotation and how to use it to write tests for the web layer in a Spring application in the Spring documentation.
