 /**
- * Exercise 1: Testing the OpenLibraryApiClient with WireMock
- * <p>
- * In this exercise, you will test the OpenLibraryApiClient using WireMock without Spring context.
- * <p>
- * Tasks:
- * 1. Create tests to verify successful API calls (status code 200)
- * 2. Create tests to verify error handling (status code 500)
- * 3. Optional: Modify the OpenLibraryApiClient implementation to handle 404 responses
- * by returning null instead of throwing an exception
- * <p>
+ * Exercise 1: Testing HTTP Clients with WireMock
+ *
+ * Your tasks:
+ * 1. Implement shouldReturnBookMetadataWhenApiReturnsSuccessResponse:
+ *    - Stub WireMock to return a 200 response with body from "__files/9780132350884-success.json"
+ *    - Call cut.getBookByIsbn("9780132350884")
+ *    - Assert the title is "Clean Code", publisher is "Prentice Hall", pages is 431
+ *
+ * 2. Implement shouldThrowExceptionWhenServerReturnsInternalError:
+ *    - Stub WireMock to return a 500 response
+ *    - Assert that calling cut.getBookByIsbn(...) throws WebClientResponseException.InternalServerError
+ *
+ * Optional:
+ * 3. Handle 404 responses gracefully by returning null instead of throwing.
+ *    Add a test shouldReturnNullWhenBookNotFound and modify OpenLibraryApiClient accordingly.
+ *
  * Hints:
- * - You can use the WireMock JUnit 5 extension (@RegisterExtension)
- * or bootstrap the WireMock server manually
- * - Use WebClient.builder() to create a WebClient instance that points to your WireMock server
- * - Check the __files directory in test resources for sample response JSON files
- * - To modify the client for 404 handling, you'll need to use .onStatus() in the WebClient call
+ * - Use wireMockServer.stubFor(get(urlPathEqualTo("/api/books")).willReturn(...))
+ * - Use aResponse().withHeader(...).withBodyFile(...) for successful responses
+ * - Use assertThatThrownBy(...).isInstanceOf(...) for exception assertions
+ * - Check Solution1WireMockTest.java if you get stuck
