Question

Create Test Controller and write the following 2 unit tests using MockMvc:

1. A test that makes a GET request to an endpoint at "/book" and verifies the HTTP response is 200.

2. A test that makes a DELETE request to an endpoint at "/book" and verifies the HTTP response is 405.

Answer 1

Two unit tests for a controller using MockMvc are demonstrated, with the first test verifying a successful GET request to '/book' by expecting a 200 HTTP status, and the second test expecting a 405 HTTP status in response to a DELETE request on the same endpoint.

Step-by-step explanation:

Writing Unit Tests with MockMvc

To test a controller using MockMvc, we write unit tests that simulate HTTP requests and check the responses. Below are examples for the given scenarios:

Test for GET Request

In this test, we use MockMvc to perform a GET request to '/book' and verify that the response status is 200, which indicates a successful request.

Test
public void shouldReturnHttpStatusOkForGetRequest() throws Exception {
mockMvc.perform(get("/book"))
.andExpect(status().is(200));
}

Test for DELETE Request

For the DELETE request, we perform a similar process but we anticipate a 405 HTTP response, which signifies that the method is not allowed on the endpoint.

Test
public void shouldReturnMethodNotAllowedForDeleteRequest() throws Exception {
mockMvc.perform(delete("/book"))
.andExpect(status().is(405));
}
