Automated performance testing of streaming services

For a professional provider of communication networks, high performance and quality of their online content are key. Ensuring real-world load simulation on servers for performance testing was a big challenge. Nagarro gathered the client's biggest pain points and brainstormed the best possible solution, like simulating end-user load on Nginx servers, testing video streaming applications while capturing network traffic for performance optimization, and load testing by using real-user browser simulation to obtain customized API results.

To overcome challenges like limited configuration and memory capacity, support for JavaScript or real-time test monitoring capabilities, and large-scale cloud-based testing, we developed a browser-based load testing framework with AWS and Puppeteer. All web server requests are now captured automatically. Real browser instances are opened on load generators. A puppeteer simulates a real user by navigating the web application using the GUI. Network traffic is recorded live, and performance is measured in real time. Logs and screen shots of every run are recorded in a performance report. This framework also enables the testing of streaming-based applications in the US, Asia & Europe regions. Our framework focuses on all dimensions of performance testing - Performance, Elasticity, Availability, Reliability, and Scalability (PEARS).
