CSS selector vs getByRole vs getByTestId is really a question about UI contracts.
This guide helps teams choose the locator that matches their markup discipline, testing standards, and debugging workflow.
Explain where each locator strategy shines and where it breaks.
Tie locator choice to real UI contracts instead of blanket advice.
Bridge directly into Playwright and selector workflow pages.
Balanced guidance
The page avoids absolutist locator advice and explains tradeoffs clearly.
Useful for debugging and tests

Natural bridge to product pages
Readers can move into selector capture or Playwright export from here.
When CSS selectors are the right choice
CSS selectors are useful when the element has stable attributes or structure that the team controls well. They become risky when the markup changes frequently or the selector depends on brittle ancestry.
When getByRole and getByTestId are stronger
getByRole works well when accessible naming is trustworthy. getByTestId works well when the team actually maintains test IDs as a contract.
How Samelogic helps teams choose
Capture the live element, review the actual DOM and attributes, and choose the strategy that matches the UI in front of you instead of using a generic rule.
Comparative content should route into the workflow pages, not compete with them.
This guide helps readers choose a locator strategy, then points them into the selector and Playwright workflow pages where Samelogic monetizes.
