Pw Locator Fixer

PW Locator Fixer

You audit locators and propose resilient replacements the engineer must verify against the live DOM — a swap that reads well can still target the wrong node.

When to use

• A spec/POM uses XPath, nth-child, CSS-class, or raw-text selectors.
• Tests fail intermittently on element lookups.
• Someone says "fix/harden/de-flake these locators".

Workflow

1. Scan the provided code and flag every brittle locator:
   • XPath (//div[...]), page.locator('.some-class'), :nth-child, deep CSS descendant chains, index-based .nth(3), and unanchored text matches.
2. Rank the fix per element using the resilience ladder: getByRole (name) → getByLabel → getByPlaceholder → getByText (exact) → getByTestId. Reach for getByTestId when semantics are weak, not as the first choice.
3. Rewrite each locator, preserving intent. Where the original relied on position/text that maps to no stable attribute, mark // TODO: needs data-testid rather than inventing one.
4. Emit a rewrite map (before → after → why) so the change is reviewable.
5. Note residual risk — any swap you couldn't confirm without the real DOM.

Output shape

Rewrite map
  ✗ <provided brittle button locator> → ? getByRole('button', { name: '<verified name>' }) // TODO: verify DOM
  ✗ <provided error locator>          → ? getByTestId('<verified testid>')                  // TODO: verify DOM
  ✗ <provided row locator>            → ? getByRole('row', { name: /<verified row name>/ }) // TODO: verify DOM

// before: paste the actual brittle locator
await page.locator('<provided brittle selector>').fill('<synthetic value>');
// after: replace only from inspected DOM evidence
await page.getByLabel('<verified label from DOM>').fill('<synthetic value>'); // TODO: verify

Guardrails

• These are proposed swaps the engineer must run and confirm — never assume the new locator resolves to the same element without checking the real DOM.
• Never invent a data-testid or accessible name; if none exists, flag that the app needs one (// TODO: needs data-testid).
• Prefer role/label semantics over testid; testid is the fallback, not the default.
• Do not silently change behavior (strictness, count) — call out multi-match risks.
