See [asynchronous code](./javascript.md#asynchronous-code). + * If a CSS file is added/modified, it follows [the CSS guidelines](./css.md). + * If a React or Redux module is added/modified, it follows the [React/Redux guidelines](./javascript.md#react--redux). + * If DevTools server code that should run in a worker is added/modified then it shouldn't use Services +* Test changes: + * The feature or bug is [tested by new tests, or a modification of existing tests](../tests/writing-tests.md). + * [Test logging](../tests/writing-tests.md#logs-and-comments) is sufficient to help investigating test failures/timeouts. + * [Test is e10s compliant](../tests/writing-tests.md#e10s-electrolysis) (doesn't try to access web content from the parent process, etc…). + * Tests are [clean and maintainable](../tests/writing-tests.md#writing-clean-maintainable-test-code). + * A try push has started (or even better, is green already). +* User facing changes: + * If any user-facing interfaces are added/modified, double-check the changes with the UX mockups or specs, if available. If there's any confusion, need-info the UX designer.<!--TODO this needs updating with the new process--> + * If a user facing string has been added, it is localized and follows [the localization guidelines](../files/adding-files.md#localization-l10n). + * If a user-facing string has changed meaning, [the key has been updated](https://developer.mozilla.org/en-US/docs/Mozilla/Localization/Localization_content_best_practices#Changing_existing_strings). + * If a new image is added, it is a SVG image or there is a reason for not using a SVG. + * If a SVG is added/modified, it follows [the SVG guidelines](../frontend/svgs.md). + * If a documented feature has been modified, the keyword `dev-doc-needed` is present on the bug. + +## Finalize the review + +* R+: the code should land as soon as possible. +* R+ with comments: there are some comments, but they are minor enough, or don't require a new review once addressed, trust the author. +* R cancel / R- / F+: there is something wrong with the code, and a new review is required. + |
