About ember-template-lint Results

Test cases that require scripts or CSS are skipped and reported as cantTell. Like all linters, Ember-template-lint does static code analysis, and so does not run scripts or render CSS.

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

Implementation Details

HTML page has lang attribute

This rule is implemented by ember-template-lint using the require-lang-attribute procedure. The implementation is partially consistent with the HTML page has lang attribute WCAG 2 rule. It covers 4 of the 7 examples. On 2 examples 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 attribute is defined in WAI-ARIA

This rule is implemented by ember-template-lint using the no-invalid-aria-attributes procedure. The implementation is fully consistent with the ARIA attribute is defined in WAI-ARIA proposed rule. It covers all 7 examples. The implementation correctly reports no success criteria are failed by this rule. See understanding ACT consistency.

ARIA state or property is permitted

This rule is implemented by ember-template-lint using the no-invalid-aria-attributes procedure. The implementation is fully consistent with the ARIA state or property is permitted proposed rule. It covers 13 of the 15 examples. On 2 examples the implementation cannot tell the outcome. This is often because of technical limitations in tools. The implementation correctly reports no success criteria are failed by this rule. See understanding ACT consistency.

Attribute is not duplicated

This rule is implemented by ember-template-lint using the no-duplicate-attributes procedure. The implementation is fully consistent with the Attribute is not duplicated proposed rule. It covers 5 of the 10 examples. On 5 examples 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.

Link is descriptive

This rule is implemented by ember-template-lint using the no-invalid-link-text procedure. The implementation is partially consistent with the Link is descriptive proposed rule. It covers 6 of the 12 examples. On 2 examples the implementation cannot tell the outcome. This is often because of technical limitations in tools. The implementation reports different success criteria as failed from what is expected by this rule. See understanding ACT consistency.

Link in context is descriptive

This rule is implemented by ember-template-lint using the no-invalid-link-text procedure. The implementation is partially consistent with the Link in context is descriptive proposed rule. It covers 11 of the 18 examples. On 3 examples 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.
