3. Adopt Page Object Model: Keep tests readable and maintainable with clear separation of concerns.

4. Run in parallel: Scale with Selenium Grid or cloud grids for faster feedback.

5. Wire into CI: Trigger suites on every change and gate merges on results.

6. Go deep on one language: Whether Java, Python, JavaScript, or C#, mastery unlocks cleaner, more reliable tests.

7. Explore Selenium 4+: Use relative locators, improved window/tab controls, DevTools integration, and the modern Grid.

8. Sharpen debugging: Add rich logging, screenshots, videos, and stepwise debugging to chase flaky failures.

9. Automate around the UI: Validate APIs, queues, files, and databases to cut brittle UI-only flows.

10. Keep current: Track releases and community practices. Refactor regularly.

Invest here and your browser tests get faster, sturdier, and easier to evolve.
