How do I write MockMvc integration tests in Spring?

To write MockMvc integration tests in Spring, you can use the MockMvc class to simulate HTTP requests. First, set up your test class with the necessary annotations like @SpringBootTest and @AutoConfigureMockMvc.

Can you show me a simple example?

Sure! Here's a basic example:

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class MyControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testGetEndpoint() throws Exception {
        mockMvc.perform(get("/api/my-endpoint"))
               .andExpect(status().isOk())
               .andExpect(content().contentType(MediaType.APPLICATION_JSON));
    }
}

What dependencies do I need for this?

You need the Spring Boot Starter Test dependency in your pom.xml or build.gradle file, which includes MockMvc.

How can I test POST requests?

For POST requests, you can use mockMvc.perform(post("/api/my-endpoint").contentType(MediaType.APPLICATION_JSON).content(jsonString)) to send JSON data.
