Testing / Playwright Interview questions

Define auto-waiting in Playwright?

Auto-waiting means Playwright automatically waits for an element to be actionable before performing an interaction, instead of requiring a manual sleep() or explicit wait call in the test code.

Before an action like click() or fill() runs, Playwright performs a series of actionability checks on the target element:

Attached to the DOM
Visible (has non-zero size and no visibility: hidden)
Stable (not still animating or mid-transition)
Enabled (not disabled)
Able to receive events (not obscured by another element)

If a check fails, Playwright retries until it passes or the action timeout is reached, then throws a descriptive timeout error naming which check failed.
