About Equal Access Accessibility Checker Results

ACT rule results were generated using the latest accessibility-checker from NPM using the ACT test driver. Results were created using the preview archive and the IBM_Accessibility policy. Mappings from ACT Rules to Accessibility Checker rule ids and reason codes can be found in the act property of rule definitions. Results indicate the rule ids and reason codes related to the ACT rule are generated in the following format:

RuleId1:ReasonCode1,ReasonCode2|RuleId2:ReasonCode3,ReasonCode4.

Results in this page are taken from a public test report published by IBM Accessibility. Data is published using the EARL+JSON-LD data format.

Implementation Details

Role attribute has valid value

This rule is implemented by Equal Access Accessibility Checker using the aria_role_allowed:Pass_0,Fail_2,Potential_1 procedure. The implementation is fully consistent with the Role attribute has valid value WCAG 2 rule. It covers 9 of the 10 examples. On 1 example the implementation cannot tell the outcome. This is often because of technical limitations in tools. The implementation correctly reports which success criteria are failed by this rule. See understanding ACT consistency.

ARIA state or property is permitted

This rule is implemented by Equal Access Accessibility Checker using the aria_attribute_valid:Pass,Fail_invalid_role_attr,Fail_invalid_implicit_role_attr procedure. The implementation is fully consistent with the ARIA state or property is permitted proposed rule. It covers all 16 examples. The implementation correctly reports which success criteria are failed by this rule. See understanding ACT consistency.

Orientation of the page is not restricted using CSS transforms

This rule is implemented by Equal Access Accessibility Checker using the element_orientation_unlocked:pass,fail_locked procedure. The implementation is partially consistent with the Orientation of the page is not restricted using CSS transforms proposed rule. It covers 8 of the 12 examples. For 4 examples no results were reported. This can happen when examples are newer then the test results. The implementation correctly reports which success criteria are failed by this rule. See understanding ACT consistency.

Element with role attribute has required states and properties

This rule is implemented by Equal Access Accessibility Checker using the aria_attribute_required:Pass_0,Fail_1, and combobox_popup_reference:Pass_1.0_expanded,Pass_1.0_collapsed,Pass_1.2_expanded,Pass_1.2_collapsed,Fail_1.2_missing_controls,Fail_1.2_popup_reference_missing procedures. Failed examples should be failed by at least one of these procedures. The implementation is fully consistent with the Element with role attribute has required states and properties proposed rule. It covers all 15 examples. The implementation correctly reports which success criteria are failed by this rule. See understanding ACT consistency.
