+# Navigation API ordering/transition tests
+
+These are meant to test the ordering between various events and promises, as
+well as in some cases how the `navigation.transition` values changes.
+
+Some of them use the `Recorder` framework in `resources/helpers.mjs`, and others
+test tricky cases (e.g. reentrancy) in a more ad-hoc way.
+
+<https://github.com/WICG/navigation-api/#complete-event-sequence> is a useful
+reference for the intent of these tests.
+
+Note:
+
+* Variants specifically exist for `currententrychange` because an event listener
+ existing for `currententrychange` causes code to run, and thus microtasks to run,
+ at a very specific point in the navigation-commit lifecycle. We want to test
+ that it doesn't impact the ordering.
+* Similarly we test that `intercept()` does not change
+ the ordering compared to no `intercept()` call, for same-document
+ navigations, by trying to ensure most variants have appropriate
+ `intercept()` counterparts with similar orderings.
+
+TODOs:
+
+* Also test `popstate` and `hashchange` once
+ <https://github.com/whatwg/html/issues/1792> is fixed.
