Make Your End-to-end Tests More Stable with Playwright's User-first Selectors

### Choosing the right locators in Playwright is key to creating stable and maintainable tests. User-first locators reduce flakiness and encourage good development practices by emulating user actions rather than HTML structure, making them more robust and reliable. By using built-in locators like getByRole, getByText, and getByLabel, developers can ensure their tests remain stable even if class names or HTML structure change. Additionally, considering element filtering and position-based selection can help resolve issues with multiple matching elements. Best practices for locator strategies include avoiding implementation details and using data test IDs to simplify locators and improve test reliability.
