Unit Tests

We plan to use Jest for unit testing due to its familiarity and overall ease of use. We are aiming for a minimum of 80% code coverage across our codebase.

Backend Testing Strategy Our backend tests will focus on data integrity, API responses, and business logic. Examples include:

• Ensuring CRUD operations for suggestions correctly update the database.
• Validating that the API returns the correct number of suggestion records when a user selects a tile, and further ensuring that the count of tile usage is being incremented and decremented properly.
• Ensuring the search API endpoint correctly filters and returns the expected payload of suggestions based on query parameters.

Frontend Testing Strategy Our frontend tests will focus on component rendering, user interface state, and user interactions. Examples include:

• Verifying that picture and audio assets are properly linked and rendered within the suggestion tiles.
• Ensuring that UI styling and colors remain consistent when suggestion tiles are dynamically added or removed from the DOM.
• Confirming that caregiver linking codes are properly fetched and displayed to the user.
