+# Hierarchical rules
+
+Axe-core handles shadow DOM and cross-domain iframe rules very well - as long as you take care in the design and implementation of your rule. Any rule that evaluates the DOM hierarchy needs to think about what happens across shadow DOM boundaries and iframe boundaries.
+
+The rule callbacks all receive both a `node` and a `virtualNode` argument (in addition to the `options` argument). `node` points to the DOM Node that is to be evaluated, whereas `virtualNode` points to the node in the flattened tree (the hierarchy that shadow DOM creates that is used for parent child relationships across shadow DOM boundaries).
+
+If your rule looks at any hierarchical context (parents or children) then you need to operate on the `virtualNode` for those operations. Calls to `isHidden` and the accessible name calculation calls will all evaluate the hierarchy. The commons and utils functions will all fetch the `virtualNode` from the flattened tree if you use the `node` implementation (and then simply call the virtualNode one) and are there for backwards compatibility. This backwards compatibility comes at a perfomance cost that can be avoided by simply using the `virtualNode` to start with. We will ask you to change this during PR review, so you might as well just start out by using the `virtualNode`.
+
+## iframes
+
+Rules that evaluate the structure and/or the number of elements on the entire page (for example the heading nesting rule, or the landmark rules) will need to do this evaluation across iframe boundaries. What this means is that the check function instead of determining pass/fail/incomplete, perfomas a data gathering function. This data is then passed up the iframe hierarchy to the top window where it is passed into the `after` function, which does the evaluation of the gathered data and determines pass/fail.
+
+## Rules of Thumb for Rule Code Reviewers
+
+Rules of thumb for determining whether `virtualNode` should be used - if any of the answers to the following questions is yes, then it should use shadow DOM and `virtualNode`:
+
+1. Is it using the non-virtualNode version of a function that wraps the flattened tree lookup?
+2. Is it evaluating the DOM hierarchy?
+
+Rules that do this MUST have shadow DOM test cases that show passes and fails across the shadow DOM boundary.
+
+Rules of thumb for determining whether an `after` function is required - if any of the answers to the following questions is yes:
+
+1. Does the rule evaluate number of things on a page?
+2. Does the rule evaluate hierarchy of things across a whole page?
+
+Rules that use an `after` function MUST have iframe test cases that assert correct data passing between iframes and handle all the relevant cases across iframes.

Subject: [PATCH 027/108] chore: disable "max-statements" and "complexity"
 ESLint rules (#1487)

This patch removes the arbitrary and ignored "max-statements" and "complexity" ESLint rules. Though the intention of having small functions with a low cyclomatic complexity is great, we have not followed these rules in practice. Instead, we've just repeatedly increased the thresholds when necessary. Doing so just adds noise for the reader of the code sift through, and is a tedious chore for the author of the code to have to do.

Subject: [PATCH 030/108] chore(marketing): Stop capitalizing the "x" in "axe"
 (#1495)

This patch replaces all instances of "aXe" with "axe". The marketing overlords have suggested we stop capitalizing the "x" in "axe" for various reasons.

It's likely that I've missed something, as this patch was generated by running a find/replace across the codebase rather than making updates individually.

 ### API Notes
 
 - A Rule test is made up of sub-tests. Each sub-test is returned in an array of 'checks'
 - The `"helpUrl"` in the results object is a link to a broader description of the accessibility issue and suggested remediation. These links point to Deque University help pages, which do not require a login.

Subject: [PATCH 031/108] feat(utils): add support for complex CSS selectors
 (#1494)

Updates the CSS Selector Parser to allow more complex selectors: `:not`, `^=`, `$=`, and `*=`. Also update docs to describe what selectors we support.

Closes: #1493

Subject: [PATCH 034/108] chore: Remove version number from axe.d.ts (#1499)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch removes the version number from `axe.d.ts`. I think the original idea behind keeping it here was to update it every time we release, but this hasn't been happening lately.

Removing the version does not have any effect on TypeScript users; instead, it just removes an easy to break/forget part of our internal processes 😃

Subject: [PATCH 035/108] feat(rule): Inline text spacing must be adjustable
 with custom stylesheets (#1446)

Ensure text spacing is not affected by inline spacing styles that affects CSS specificity

Closes issue:
- https://github.com/dequelabs/axe-core/issues/1301

**Note: to make sure to make it clear in the failure message that this is due to limited support for custom stylesheets.**

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes some HTML issues (extra closing tags, mismatched tags, etc). This enables us to run Prettier over our HTML files (PR incoming).

I assume these HTML issues were accidental 🤷‍♀️

Subject: [PATCH 042/108] fix(raw-reporter): do not output `DqElement`s (#1513)

This patch updates our "raw" reporter, ensuring it does not pass `DqElement`s to its callback. Instead, it serializes the `DqElement` by using the `DqElement#toJSON()` method.

Unfortunately many of our tests pass non-results to the reporters, so several "guards" were added to the reporter ensuring we don't error while attempting to transform the provided results. In an ideal world, these tests would be rewritten to pass "proper" result objects to our reporters, but this felt out-of-scope for the task at hand.

Closes https://github.com/dequelabs/axe-core/issues/1195

 | `cssom`    | This asset type preloads all CSS Stylesheets rulesets specified in the page. The stylesheets can be an external cross-domain resource, a relative stylesheet or an inline style with in the head tag of the document. If the stylesheet is an external cross-domain a network request is made. An object representing the CSS Rules from each stylesheet is made available to the checks evaluate function as `preloadedAssets` at run-time |
 
 The `timeout` attribute in the object configuration is `optional` and has a fallback default value (10000ms). The `timeout` is essential for any network dependent assets that are preloaded, where-in if a given request takes longer than the specified/ default value, the operation is aborted.

Subject: [PATCH 081/108] docs: Add CircleCI status badge (#1595)

This patch adds a CircleCI status badge to our README. This enables users to see how stable the `develop` branch is and allows us to quickly navigate to the `axe-core` landing page in CircleCI (which is something I do frequently).

Subject: [PATCH 089/108] feat(rule): Adding landmark-is-unique rule (#1394)

* Initial attempt at landmark-unique rule

* Adding matches tests WIP

* Re-factored and added tests for matches function

* Added support for virtual nodes

* Using findUp api instead of looking up the tree ourselves

* Migrated unique-ness logic to after and removed code

* Added tests for landmark-is-unique-after

* Added best practice tag to unique landmark rule

* Added test for form elements

* Added comment to explain filtering in landmark matches function

* Changed usage of actual node with virtual node where possible in landmark-unique-matches

* Use related nodes api instead of failing duplicate landmarks

* Updated landmark is unique check test to validate related nodes

* Added a failing iframe test for landmark-unique

* Added a test case for matching landmark-unique against elements in shadow dom

* Implement own findIndex for landmark-is-unique to unblock tests

* Used find instead of findIndex (from polyfills)

* Updated the landmark-unique-matches to use the virtual node by default

* Updated nodeName usage to upper case

* Exit early when no role is found in landmark unique matches

* Added test for heirarchical exclusions in shadow dom for landmark-unique-matches

* Took out common variables in landmark unique matches tests

* Added more iframe integration tests for landmark-unique rule

* PR changes: label to accessibleText, ES3 support in tests, and remove options since not used

* Added more integration test cases

* Updated text for new rule

* One last const to var

* Updated to remove all const/let uses

* Use accessibletextvirtual

* Fixed test by passing virtual node in to landmark is unique

* sync upstream/develop

* remove es6 syntax from tests

* cleanup

* fix typo

+Axe requires a handful of global variables and interfaces to be available in order to run. See the [jsdom example](https://github.com/dequelabs/axe-core/blob/develop/doc/examples/jsdom/test/a11y.js) for how to set these up in a non-browser environment.
