1854660 - Temporarily disable some Tier 2 a11y_checks for Search and Address Bar

Status: RESOLVED FIXED

(Firefox :: Search, task, P3)

Description

[Anna Yeddi [:ayeddi]]

We are working on enabling Tier 2 a11y-checks to ensure our products have basic accessibility built-in (bug 1692110) and before that, we need to prepare the existing code base. While we triage and investigate existent tests that would fail once the a11y-checks are enabled in the CI, we are going to skip the failing tests altogether and then handle each one of them individually.

This task is to skip with fail-if condition of the failing tests while we continue investigation into the reasons these tests failed and to be able to backtrack these tests once they're resolved. A separate task to investigate the failed Tier 2 a11y_checks will be filed for an appropriate component.

Some of similar test failures were reported in [Session Restore](bug 1854529) and [Tabbed Browser](bug 1854507) components as well.

Jobs affected:

1. test-linux1804-64-qr/opt-mochitest-browser-chrome-swr-a11y-checks-${1-7} (Try run)

---

Some Tier 2 accessibility checks for click events fired on controls that should be keyboard accessible and have valid labels were failing for this component. They were captured by testing/mochitest/tests/SimpleTest/AccessibilityUtils.js via bug 1692110. These failing tests should be temporarily skipped in the directory's browser.ini file while we investigate these failures. For all confirmed bugs individual defects should be filed.

When the individual test failures are resolved and the individual bugs are closed, remove the fail-if condition for a11y_checks from the appropriate files/sections to ensure better test coverage and to avoid regressions in a11y of these components.
