TCS QA Engineer Interview Questions

"To build a scalable framework, I use Playwright with TypeScript and implement the Page Object Model (POM) to separate test scripts from page-specific element locators. I set up configuration hooks to manage test data for local, staging, and production environments, and integrate the test suite in our GitHub Actions CI pipeline to run tests automatically on code merge."

"I document bugs by writing a concise title detailing the issue, followed by clear, step-by-step reproduction instructions. I explicitly list the Expected Behavior vs Actual Behavior. I attach system console logs, network payloads, device environment details, and screen recordings, and assign a critical priority based on customer impact."

"Boundary Value Analysis is a test case design technique that focuses on testing values at the boundaries of valid and invalid input ranges. For example, if a text field accepts a password between 8 and 16 characters, I test exactly 7 (invalid lower boundary), 8 (valid lower boundary), 15 (valid interior), 16 (valid upper boundary), and 17 (invalid upper boundary) characters, as boundary values are the most common source of system errors."
