Testing Your WebRTC Application – The Best Testing Practices

Like all the other software offerings, Testing is vital for the WebRTC Applications as well. In this blog, we share with you some of the best practices that we leverage while testing our Bespoke WebRTC applications. 

WebRTC has many important components – user devices, signaling servers, the application server, TURN and STUN servers, and sometimes media servers. The aspects where you need to focus on WebRTC may depend on the use case and the chosen architecture. Here are various aspects that we like to take into consideration when building a test plan for the WebRTC application.

End to end WebRTC testing

WebRTC applications enable the users to have end-to-end interaction using your service. This implies that you must focus on end to end WebRTC testing in a fashion that is as close as possible to how your real users interact with your service.

RTCWeb.in understands the importance of end-to-end testing! If we are building your application, we consider the following to perform end to end WebRTC testing.

Manual Testing – QA experts test the services as your end-users will. They consider the impact of different network conditions and locations on your WebRTC applications.

Automated Testing – The end to end testing can also be automated using SaaS platforms like testRTC. In automated testing, more than 80% of the scenarios are covered.

User Testing – Releasing the product to a small number of users for the first-impressions, reactions, usage patterns, and feedback. 

P2P Testing – Is P2P testing needed? Yes, it is. Even if your application provides 1:1 calls in a peer-to-peer setup, we will recommend that you opt for testing. The main concern with P2P is the scale and uptime of the signaling server. However, since no actual media is part of application infrastructure other than TURN servers, testing becomes easy.

Mobile Testing – Testing on mobile devices brings in different sets of challenges compared to the web browser. With the web browsers, the browser owner is in charge of the WebRTC implementation on the device. But, in regards to a mobile application, you are the one in charge of everything: WebRTC implementation, WebRTC stack used, modifying it, updating it, etc. 

Functional and Coverage Testing – Dealing with all the functionalities of an application is important, but daunting process. We have extensive experience in WebRTC technology and do understand that while there are a lot many testing tools available, very few are focused on WebRTC. A generic testing tool may not fulfill the requirements of WebRTC. This may include the geographic spread, machine configurations, network conditions, and so on. 

On the other hand, if we use WebRTC focused testing tools, perhaps other crucial features and requirements will be ignored. We opt for using multiple tools to ensure full coverage of our WebRTC applications.

WebRTC Interoperability Testing  – WebRTC interoperability testing is complicated. Interoperability simply means the application’s capability to interact with other Vendors/applications. There are two kinds of interoperability:

  • Browser interoperability – How compatible browsers are with each other? This is something browser vendors deal with. As developers and as application owners, we don’t have to worry about that.
  • Service interoperability – Our service (our application) needs to work well with all the browsers. How do we achieve this – by keeping pace with browser vendors.

Testing Your WebRTC Applications – 

There are some WebRTC testing tools that feature in our process as well. These tools can make WebRTC testing very easy and effective. Here is a small list of such tools. 

TestRTC – TestRTC amongst the world’s most powerful WebRTC testing and monitoring platforms. For companies serious about WebRTC, this is the platform that covers all the bases.

Kite – Kite is an effortless way to test WebRTC compliance, allowing to write automated interoperability test scripts in Java and run them on any platform. 

WebRTC-internals – Webrtc-internals is a tool to find issues with your WebRTC applications. Be it for testing WebRTC to debug an issue or to tweak with your existing configuration, WebRTC-internals is the most trustworthy platform to trust.

So, sit down with our team. Identify the areas that should be covered in your WebRTC testing. Leave everything on our team and ask for a fully functional app and well-tested application.
