Acceptance test

Non-functional acceptance testing assesses quality attributes of system features that extend beyond functional correctness.

Test ID	Scenario	Action	Expected Result
1	Deleting word tiles	User selects back button or trash button	A word tile is removed from the sentence bar with the backspace button or all tiles currently in the sentence bar is removed with the trash button
2	Selecting a word tile and constructing a sentence	User selects any word tile from the AAC board with audio output	The word tile appears on the sentence bar and the word associated with the tile will be audibly played
3	Navigating the AAC board	User selects category tiles and back button	Word tiles associated with the category is displayed and taken back to the default tile grid
4	Using the next-word suggestion bar	User sees the next-word suggestion bar updating as they are constructing a sentence	The next-word suggestion bar will change based on bigrams and trigrams they have used previously as they add words to the sentence bar.
5	Audio quality	User selects a word tile or play word to speech button	Audio is clear and played within 1 second of selecting a word tile or the word to speech button.

• Content has been expanded from brief bullet points to comprehensive acceptance criteria that address overall quality.
• This section addresses usability, performance, reliability, security and privacy, compatibility, and maintainability.
• The revised wording aligns with the conventions of a formal acceptance test report.

Scenario	Action	Expected Result	Actual Result	Status
Navigation consistency	Navigate between child and caregiver flows using AAC entry points	Navigation is intuitive and consistent across role-based views	Caregiver actions are discoverable via dedicated entry points; child view remains clean and focused	PASS
Non-text content	Use icon/image-based controls in main workflows	Icons and visual elements are clear, recognizable, and intuitive	Users could complete targeted tasks using icon-driven actions without confusion	PASS
Contrast and visual clarity	Evaluate readability of text, icons, and controls in normal usage	Interface meets AASPIRE and WCAG-aligned contrast and clarity expectations	UI remained readable and visually clear during manual validation in target environment	PASS
Performance responsiveness	Perform authentication, grid interaction, and suggestion search under normal conditions	Core interactions respond without noticeable blocking	Core interactions were responsive during manual validation and test execution	PASS
Reliability of core flows	Repeat sign in/out, student linking, and search across refresh cycles	Core flows remain stable without data corruption or inconsistent behavior	Sign in/out, student linking, and suggestion operations behaved consistently over repeated runs	PASS
Security and privacy controls	Attempt caregiver-only actions before and after authentication	Restricted features require valid authentication and are protected from unauthorized access	Caregiver-only features were inaccessible until successful caregiver authentication	PASS
Maintainability and testability	Review modularity, automated tests, and acceptance documentation coverage	Changes are testable, documented, and maintainable with low regression risk	Automated caregiver service tests pass and acceptance outcomes are documented in this report	PASS
