@ExtendWith(MockitoExtension.class)
class ExceptionHandlerControllerAdviceTest {

  /**
   * Given a handle invalid exception when controller advice then return a bad request 
exception.
   */
  @Test
  void handleInvalidFormatException() {
    GlobalExceptionHandler controllerAdvice = new GlobalExceptionHandler();
    ResponseEntity<?> response = controllerAdvice.handleAllExceptions(null, null);
    assertEquals(HttpStatus.BAD_REQUEST.value(), response.getStatusCode().value());
