+# Tests
+
+For normative changes, a corresponding
+[web-platform-tests](https://github.com/w3c/web-platform-tests) PR is highly appreciated. Typically,
+both PRs will be merged at the same time. Note that a test change that contradicts the spec should
+not be merged before the corresponding spec change. If testing is not practical, please explain why
+and if appropriate [file an issue](https://github.com/w3c/web-platform-tests/issues/new) to follow
+up later. Add the `type:untestable` or `type:missing-coverage` label as appropriate.
