How do you manage session handling in parallel Selenium tests?

Managing session handling in parallel Selenium tests requires careful isolation of WebDriver instances. I ensure each test thread initiates its own WebDriver session to prevent conflicts. Utilizing thread-local storage for WebDriver instances is a reliable strategy for maintaining session independence. During my Selenium course online, I learned to integrate test frameworks like TestNG and JUnit with parallel execution capabilities, using annotations and configuration files to manage parallelism effectively. It’s also important to clean up sessions properly after each test to avoid memory leaks or stale sessions. This approach guarantees reliable, conflict-free test execution in parallel test environments.
