### Question:
CacheApi { public PutCachesResponse switchCache(PutCachesRequest body) throws ApiException { ApiResponse<PutCachesResponse> resp = switchCacheWithHttpInfo(body); return resp.getData(); } CacheApi();  CacheApi(ApiClient apiClient); ApiClient getApiClient(); void setApiClient(ApiClient apiClient); com.squareup.okhttp.Call retrieveAllCall(final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); List<GetCachesResponse> retrieveAll(); ApiResponse<List<GetCachesResponse>> retrieveAllWithHttpInfo(); com.squareup.okhttp.Call retrieveAllAsync(final ApiCallback<List<GetCachesResponse>> callback); com.squareup.okhttp.Call switchCacheCall(PutCachesRequest body, final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); PutCachesResponse switchCache(PutCachesRequest body); ApiResponse<PutCachesResponse> switchCacheWithHttpInfo(PutCachesRequest body); com.squareup.okhttp.Call switchCacheAsync(PutCachesRequest body, final ApiCallback<PutCachesResponse> callback);  }### Answer:
@Test public void switchCacheTest() throws ApiException { PutCachesRequest body = null; PutCachesResponse response = api.switchCache(body); }
