Selenium to Playwright: A Practical Migration Guide to TypeScript, Modern Test Architecture, CI/CD, and Reliable End-to-End Testing
Struggling with unreliable Selenium tests or wondering how to move to Playwright without losing the work you've already done?
Selenium to Playwright gives you a practical, step-by-step path from an existing Selenium test suite to modern browser automation with TypeScript. You don't need previous Playwright or TypeScript experience. Basic programming knowledge is helpful, and every new technique is explained through manageable examples.
Follow a continuous OrderDesk sample project as you assess legacy tests, migrate real browser interactions, improve test architecture, and build reliable end-to-end testing workflows. You'll learn why tests fail, how to troubleshoot them, and how to measure migration success before retiring Selenium coverage.
