### Question:
AnotherFakeApi { public Mono<Client> call123testSpecialTags(Client body) throws WebClientResponseException { Object postBody = body; if (body == null) { throw new WebClientResponseException("Missing the required parameter 'body' when calling call123testSpecialTags", HttpStatus.BAD_REQUEST.value(), HttpStatus.BAD_REQUEST.getReasonPhrase(), null, null, null); } final Map<String, Object> pathParams = new HashMap<String, Object>(); final MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<String, String>(); final HttpHeaders headerParams = new HttpHeaders(); final MultiValueMap<String, String> cookieParams = new LinkedMultiValueMap<String, String>(); final MultiValueMap<String, Object> formParams = new LinkedMultiValueMap<String, Object>(); final String[] localVarAccepts = { "application/json" }; final List<MediaType> localVarAccept = apiClient.selectHeaderAccept(localVarAccepts); final String[] localVarContentTypes = { "application/json" }; final MediaType localVarContentType = apiClient.selectHeaderContentType(localVarContentTypes); String[] localVarAuthNames = new String[] { }; ParameterizedTypeReference<Client> localVarReturnType = new ParameterizedTypeReference<Client>() {}; return apiClient.invokeAPI("/another-fake/dummy", HttpMethod.PATCH, pathParams, queryParams, postBody, headerParams, cookieParams, formParams, localVarAccept, localVarContentType, localVarAuthNames, localVarReturnType); } AnotherFakeApi(); @Autowired  AnotherFakeApi(ApiClient apiClient); ApiClient getApiClient(); void setApiClient(ApiClient apiClient); Mono<Client> call123testSpecialTags(Client body);  }### Answer:
@Test public void call123testSpecialTagsTest() { Client client = null; Client response = api.call123testSpecialTags(client).block(); }
