We had to remove this test: void downloadedDataTest() { rtFileCache::instance()->clearCache(); addDataToCache("http://fileserver/file.jpeg",getHeader(),getBodyData(),fixedData.length()); rtFileDownloadRequest* request = new rtFileDownloadRequest("http://fileserver/file.jpeg",this); expectedStatusCode = 0; expectedCachePresence = true; expectedHttpCode = 200; (1) rtFileDownloader::instance()->downloadFile(request); char *data = new char [1000]; size_t size = 0; memset (data, 0, 1000); (2) request->downloadedData(data, size); //since the data would have been consumed by callback EXPECT_TRUE (size == 0); delete[] data; sem_wait(testSem); } Because it is not possible to invoke (2) after (1) has finished ('request' is being deleted in the end of downloadFile() method).
