Checkpoints represent a proven method for accessibility requirements testing created by Deque's team of a11y experts that increases the consistency and accuracy of testing results. Based on the WCAG Success Criteria, they provide a more detailed categorization and interpretation of those guidelines, wherein failures are typically separated by content type. The Deque Checkpoints help reviewers produce consistent and accurate test results during accessibility assessments.
Checkpoint Tests consist of several sections of information.
- Rule Description: Each individual checkpoint test is based on a statement of a rule, guideline requirement, or best practice that describes what to test for the presence of. These are typically one or two sentences written as "must" statements.
- Testing Methodology: Typically an ordered list of sequential task steps that make up the recommended testing procedure.
- Validation: When relevant, information is provided to let you know how to validate the testing methodology used.
- Mobile: Procedures for testing on devices using mobile operating systems such as iOS and Android are provided.
- Native Mobile: Procedures for testing native mobile apps.
- PDF: Procedures for testing Portable Document Format (PDF) documents.
- Assistive Technology: Specific testing guidance as it relates to the software and devices used by disabled individuals to interact with software and websites. Some tests will require use of a screen reader, such as NVDA or JAWS on PC, or VoiceOver on Mac.
- Related Links: Categorized groups of links such as General, HTML, and ARIA-specific resources to both Deque University materials and trusted external sites that contain related information. These may include links to Techniques, Examples and Best Practices.
- Disabilities Affected: One or more of the following is displayed to indicate which disabilities are impacted by the rule not being met:
- Attention Deficit
- Low Vision
- Sighted Keyboard Users
