Parallel Testing Redefined:
The Browserpooling Method
About Topic
Private browsing modes, such as Chrome’s incognito mode and Firefox’s private mode and containers, serve the common purpose of ensuring privacy during browsing. Although the underlying implementations differ, they share key features such as not storing browsing history and cookies, hence enhancing user privacy. While this feature is useful for regular users, it’s a powerhouse for automation engineers and testers. WebDriver BiDi offers a browser-agnostic method to utilize private browsing through User Contexts, cultivating a ‘browserpooling’ approach. This approach allows multiple tests to share a single browser instance and WebDriver session, facilitating parallel test execution. Like carpooling, where multiple passengers share a single ride to different destinations, WebDriver BiDi’s user contexts enable parallel tests to utilize a single browser instance without sharing data. This provides performance gains by eliminating the time-consuming process of spinning up and shutting down multiple browser instances.
Join this session to explore how user contexts operate, how to manage isolated tests and cookies across multiple tabs and gain insights with a live code demo on leveraging this technique in Selenium.

Key Takeaways
- Learn how to optimize testing environments by using a single browser instance.
- Practical knowledge of using WebDriver BiDi’s user context with code examples.
- Understand real-world use cases where this method can lead to performance gains and reduce the total runtime of automation tests.
