Loadero simplifies creation, running and hosting of end-to-end tests for real-time communications applications. These tests will exercise all flows involved in the application and provides a way to do performance assertions. Loadero can be used to test webRTC applications that require webcam and microphone inputs. Once the tests have finished running, webRTC statistics like jitter, latency and bandwidth are available for analysis. If certain thresholds for statistics are known, they can be enforced with post-run assertions.
