Designing Robust Session Management in Distributed Playwright Tests
🤯 Playwright Distributed Test Challenge: Are your distributed Playwright tests battling shared state and flaky cleanups? Learn to design robust, isolated sessions. 📌 Problem Statement Large-scale Playwright test suites often run concurrently across multiple workers. When these tests interact with shared, stateful backend resources (e.g., Kafka topics, temporary databases), ensuring each worker…
The article discusses the challenges of creating robust, isolated sessions in large-scale Playwright test suites that run concurrently across multiple workers. It emphasizes the need to avoid reliance on global state or manual cleanup, as these can lead to flakiness and orphaned resources. The solution proposed involves using Playwright's `test.extend` function to create custom fixtures that manage unique session IDs and associated resources.
This approach ensures that each worker has its own isolated context, with guaranteed setup and cleanup. The code example provided demonstrates how to implement these fixtures, including acquiring a unique ID, creating a browser context with that ID, and ensuring proper cleanup after the test completes or fails.
