What are the Causes of ProtocolError in Playwright?

A ProtocolError in Playwright typically occurs due to communication issues between Playwright and the browser, often arising from browser compatibility problems, WebSocket disconnections, network issues, timeouts, concurrent operations, incorrect API usage, browser crashes, or version mismatches. To avoid these errors, it's essential to ensure compatibility between Playwright and browser versions, maintain stable network connections, manage WebSockets, optimize test execution, and handle operations sequentially and asynchronously. The text also highlights the benefits of using AI-driven tools like testRigor, which simplify the testing process by allowing the creation of test cases in plain English, managing waits and timeouts automatically, and providing robust integrations with various platforms. These tools can significantly reduce maintenance efforts and improve test coverage, allowing testing teams to focus more on exploratory testing and creating robust test cases.
