+# How to write back-forward cache tests
+
+In the back-forward cache tests, the main test HTML usually:
+
+1. Opens new executor Windows using `window.open()` + `noopener` option,
+ because less isolated Windows (e.g. iframes and `window.open()` without
+ `noopener` option) are often not eligible for back-forward cache (e.g.
+ in Chromium).
+2. Injects scripts to the executor Windows and receives the results via
+ `RemoteContext.execute_script()` by
+ [/common/dispatcher](../../../../common/dispatcher/README.md).
+ Follow the semantics and guideline described there.
+
+Back-forward cache specific helpers are in:
+
+- [resources/executor.html](resources/executor.html):
+ The BFCache-specific executor and contains helpers for executors.
+- [resources/helper.sub.js](resources/helper.sub.js):
+ Helpers for main test HTMLs.
+
+We must ensure that injected scripts are evaluated only after page load
+(more precisely, the first `pageshow` event) and not during navigation,
+to prevent unexpected interference between injected scripts, in-flight fetch
+requests behind `RemoteContext.execute_script()`, navigation and back-forward
+cache. To ensure this,
+
+- Call `await remoteContext.execute_script(waitForPageShow)` before any
+ other scripts are injected to the remote context, and
+- Call `prepareNavigation(callback)` synchronously from the script injected
+ by `RemoteContext.execute_script()`, and trigger navigation on or after the
+ callback is called.
+
+In typical A-B-A scenarios (where we navigate from Page A to Page B and then
+navigate back to Page A, assuming Page A is (or isn't) in BFCache),
+
+- Call `prepareNavigation()` on the executor, and then navigate to B, and then
+ navigate back to Page A.
+- Call `assert_bfcached()` or `assert_not_bfcached()` on the main test HTML, to
+ check the BFCache status. This is important to do to ensure the test would
+ not fail normally and instead result in `PRECONDITION_FAILED` if the page is
+ unexpectedly bfcached/not bfcached.
+- Check other test expectations on the main test HTML,
+
+as in [events.html](./events.html) and `runEventTest()` in
+[resources/helper.sub.js](resources/helper.sub.js).
+
+# Asserting PRECONDITION_FAILED for unexpected BFCache eligibility
+
+To distinguish failures due to unexpected BFCache ineligibility (which might be
+acceptable due to different BFCache eligibility criteria across browsers),
+`assert_bfcached()` and `assert_not_bfcached()` results in
+`PRECONDITION_FAILED` rather than ordinal failures.

+# Overlapping navigation and traversal tests

+These tests follow the behavior outlined in the
+[session history rewrite](https://github.com/whatwg/html/pull/6315).
+
+<https://github.com/whatwg/html/issues/6927> discusses these results.
+
+We are not yet 100% sure on this behavior, especially for overlapping
+traversal cases where the spec is complex and some of the tests don't
+seem to match any browser. Please feel free to discuss on the spec
+issue.

+<!--
+ In the spec, all traversals are queued, and that includes computing what
+ "back" and "forward" mean, based on the "current session history step". The
+ "current session history step" is updated at the end of "apply the history
+ step", at which point the queued steps in "traverse history by a delta" get to
+ run and compute what is back/forward. So the basic structure is:
+
+ - back(), back(): go back once, then again.
+ - back(), forward(): go back once, then go forward.
+
+ However, note that these observable effects (e.g., actually loading an
+ intermediate document) are done via queued tasks. Those tasks will end up not
+ running, once we switch the active document due to the second traversal. So
+ the end observable result looks like:
+
+ - back(), back(): go back -2.
+ - back(), forward(): go nowhere.

+
+<!--
+ This test asserts that an ancestor canceling a cross-origin descendant's
+ ongoing navigation does not result in load events firing in the ancestor
+ synchronously.
+
+ The reason this test uses a grandparent/grandchild pair to represent the
+ ancestor/descendant, instead of a parent/child pair, is because if a child
+ frame is blocking its parent window's load event, that means the child frame
+ navigation is being made from the initial about:blank Document to some
+ resource, and the initial about:blank child is synchronously scriptable from
+ the parent since they share the same window agent. This test is trying to
+ capture the scenario where the descendant document (that owns the ongoing
+ navigation) is hosted/scheduled on a different agent than the ancestor
+ document that cancels the descendant's ongoing navigation. The only way to do
+ this is to have a grandparent frame load a cross-origin child, whose document
+ itself loads a child frame that has a very slow ongoing navigation. That way
+ the grandparent can reach the grandchild via `window.frames[0].frames[0]`,
+ which is a proxy to the document living in a different agent.

+ * This provides a more friendly interface to remote contexts in dispatches.js.
+ * The goal is to make it easy to write multi-window/-frame/-worker tests where
+ * the logic is entirely in 1 test file and there is no need to check in any
+ * other file (although it is often helpful to check in files of JS helper
+ * functions that are shared across remote context).
+ *
+ * So for example, to test that history traversal works, we create a new window,
+ * navigate it to a new document, go back and then go forward.
+ *
+ * @example
+ * promise_test(async t => {
+ * const rcHelper = new RemoteContextHelper();
+ * const rc1 = await rcHelper.addWindow();
+ * const rc2 = await rc1.navigateToNew();
+ * assert_equals(await rc2.executeScript(() => 'here'), 'here', 'rc2 is live');

+ * rc1.historyForward();
+ * assert_equals(await rc2.executeScript(() => 'here'), 'here', 'rc2 is live');
+ * });
+ *
+ * Note on the correspondence between remote contexts and
+ * `RemoteContextWrapper`s. A remote context is entirely determined by its URL.
+ * So navigating away from one and then back again will result in a remote
+ * context that can be controlled by the same `RemoteContextWrapper` instance
+ * before and after navigation. Messages sent to a remote context while it is
+ * destroyed or in BFCache will be queued and processed if that that URL is
+ * navigated back to.
+ *
+ * Navigation:
+ * This framework does not keep track of the history of the frame tree and so it
+ * is up to the test script to keep track of what remote contexts are currently
+ * active and to keep references to the corresponding `RemoteContextWrapper`s.
+ *
+ * Any action that leads to navigation in the remote context must be executed
+ * using
+ * @see RemoteContextWrapper.navigate.

+# Origin-keyed agent clusters tests
+
+These are tests for the [origin-keyed agent clusters](https://html.spec.whatwg.org/multipage/origin.html#origin-keyed-agent-clusters)
+feature.
+
+## Test filenames
+
+The tests in `2-iframes` follow the file naming pattern
+
+```
+parent-[yes|no]-child1-[yes|no]-[designator]-child2-[yes|no]-[designator]
+```
+
+Here:
+
+* `yes` or `no` refers to whether the `Origin-Agent-Cluster` header is set or
+ unset.
+* `designator` explains how the child differs from the parent: e.g. by being a
+ subdomain, or having a different port, or both. There's also `same` if it's
+ same-origin.
+
+Other directories have variations on this, e.g. `1-iframe/` does the same thing
+but for a single `child` instead of `child1` and `child2`, and `navigation/`
+uses `1` and `2` to represent the two different locations the single iframe will
+be navigated to.
+
+## Coverage
+
+Header parsing is covered by a few tests in the `1-iframe/` subdirectory, and
+not duplicated to all other scenarios.
