With the increasing demand for remote communications and collaboration, the use of WebRTC has significantly grown and skyrocketed. From niche technology, it is mission-critical for many organisations and people worldwide. The number of video conferencing platforms leveraging WebRTC has also increased, making the competition more challenging - as such, testing your WebRTC app to ensure it ticks all the boxes has also contributed to any platform’s success. 

This article will explore why WebRTC testing is crucial to video conferencing platforms and WebRTC vendors.

What is a WebRTC test and WebRTC testing?

WebRTC (Web Real-Time Communication) testing involves various methodologies and tools to ensure real-time web browser communication applications function and perform seamlessly. The essence of WebRTC testing lies in validating both the functional and non-functional aspects of these applications. 

  1. Functional testing: This focuses on verifying the core functionalities, such as signalling logic, media connectivity, and user interaction, to ensure the application works as intended.
  2. Non-functional testing: On the other hand, non-functional testing dives into aspects like performance under different network conditions, scalability to handle many users, and quality of experience delivered to the end-users.

The objective is to identify and rectify issues that may slow down the real-time communication capabilities of WebRTC applications, ensuring they deliver a reliable and high-quality user experience.

How to test WebRTC?

Device resources

In testing WebRTC applications, it's essential to consider the different devices and browsers that end-users might employ. Device resources like CPU, memory, and network capabilities can significantly impact the WebRTC application's performance. 

It's advisable to test across various devices, including mobiles, tablets, desktops, and different operating systems and browsers, to ensure compatibility and optimised performance.

Server-side infrastructure

WebRTC relies on various server types, including signalling servers, media servers, and STUN/TURN servers. Ensuring these servers operate under stress and over extended periods is crucial. Conduct soak tests to understand the system's capacity, like how many calls per second your service can handle. 

Identifying your infrastructure's breaking point, whether CPU utilisation or network traffic, is essential to optimise the server-side infrastructure and ensure it can handle real-world usage scenarios.

Network conditions

Network conditions are dynamic; they can fluctuate over time, affecting the WebRTC application's performance. Conduct tests to determine how quickly your media servers return to high bitrate and high frame rate operation after experiencing low bitrate or high packet loss periods. 

It's also crucial to check how the media server copes with different network conditions, ensuring each user receives the necessary treatment and video streams irrespective of network variations. Ensure your WebRTC application operates well under various network conditions, especially where packet losses and bandwidth restrictions are expected.

User behaviour

Understanding user behaviour is vital in testing WebRTC applications. While automation is crucial, human behaviour with interactive WebRTC services can present unexpected scenarios, necessitating real people to test your service. 

For instance, multiple users might attempt to join simultaneously in larger meetings or growing services, potentially stressing the system. Testing should validate whether the WebRTC services can handle such scenarios where many users are connecting simultaneously, ensuring a smooth user experience under varying user behaviour conditions.
