Restructure and expand tests for AudibleService: replace a single hoisted axios client mock with separate htmlClientMock and apiClientMock, update axios.create to return clients in initialization order, and remove the fs mock. Add reusable fixture helpers (makeProduct, makeProductsResponse, apiResponse) and many new/spec-complete test cases organized into describe blocks (initialization, search, mapping, series rules, author search, popular/new releases, categories, and audiobook details). Improve assertions for pagination, deduplication, field mapping, error handling, and region/config behavior; reset and clear mocks in beforeEach to ensure isolation.
Introduce user-reported-issues and Goodreads shelf sync features and wire them into notifications. Adds Prisma migrations and schema changes (ReportedIssue, GoodreadsShelf, GoodreadsBookMapping), API endpoints for reporting (POST /audiobooks/[asin]/report-issue) and admin management (list, resolve/dismiss, replace), and an admin UI section to view/dismiss/replace reported issues. Adds a new notification event (issue_reported) with updates to notification schemas, docs and provider handling, plus a notification-events constants file. Refactors request creation to use createRequestForUser service, adds a Goodreads sync processor/service/hooks/UI modals, a scrape-resilience util, and related tests and minor integration updates.
Adds file hash-based matching for Audiobookshelf library items to ensure 100% accurate ASIN assignment for RMAB-organized content. Removes fuzzy matching from library availability checks, making all matching ASIN-only to eliminate false positives and race conditions. Updates database schema, processors, and matcher utilities; adds new tests and documentation for the new matching strategy. Removes obsolete scripts, Dockerfile, and related tests; updates docker-compose for test environments.
Introduces a fetchWithRetry method to handle network errors and rate limiting (503, 429) with exponential backoff in AudibleService. Updates getPopularAudiobooks and getNewReleases to use this retry logic and improves error handling to stop pagination on errors but return collected results. Test cases are updated to use non-retryable errors (404) for more accurate coverage.
Introduced a Vitest-based backend unit testing framework with supporting scripts, helpers, and GitHub Actions integration. Refactored the admin settings page to a modular architecture, splitting monolithic logic into feature-specific tabs and hooks for improved maintainability and testability. Updated documentation to reflect the new testing setup and settings architecture, and added new dependencies for testing utilities.
