Testing

Just as testing marks the beginning of SDLC, testing is the milestone for project competition. By now, we should have an efficient WebRTC web project capable of video/audio calls, messaging, Geolocation, and so on. It is time to test the functionality and search for bugs that might have crept in to the code.

Testing the signal flow

Wireshark is a good tool to monitor all of the traffic flow between connected machines. We can test the packets sent and received, and generate flow diagrams to visualize the call flow between parties, end points, as well as the server. The following screenshot shows the Wireshark tool analyzing signal traces:

To filter the packets captured by Wireshark as per our need, filter it using sip||websocket as shown in the preceding screenshot.

Test cases for WebRTC client validation

Test cases are used for validation and verification of the end product. The test cases in the following table are to gauge the correct working of the WebRTC client in known situations...
