Best practices and careers

Write maintainable automation and grow as an automation engineer.

📖 Key ideas

Automate what matters: critical, stable flows.
Keep tests independent with clean test data.
Use explicit waits and stable locators.
Review flaky tests promptly.
Roles: automation tester, SDET; skills: programming, Selenium/Playwright, API testing, CI.

💡 Real-life example: Good automation is a well-maintained garden: prune flaky tests, water with fresh data, grow steadily.
