The tests provide comprehensive coverage for all functions in lib/ai/file-compatibility.ts, including edge cases for media type compatibility (images, PDFs, text), model-specific validations (using real models like Gemini 2.5 Flash and GPT-OSS 20B), error message generation, supported file type listings, model compatibility filtering, and File object type mapping (e.g., handling 'image/jpg' as 'image/jpeg'). This adds unit test coverage to ensure the file upload compatibility logic is robust and maintains behavior across different AI models. No changes were needed to the source file, but tests validate its current implementation. Linting for unused variables was attempted but failed due to repo ESLint config issues (no eslint.config.js); manual review confirms no unused vars in the new file. + +### lib/db/queries.test.ts + +- Lines touched: +1 / -0 +- Key changes: No detailed change summary recorded. + +### components/message-actions.tsx + +- Lines touched: +65 / -82 +- Key changes: + - Added JSDoc for components. + - Refactored upvote/downvote onClick handlers using handleVote('up'|'down'). + - Added data-testid to copy elements. + - Minor: Improved string interpolation in toasts for consistency. + +### components/drag-drop-wrapper.test.tsx + +- Lines touched: +181 / -0 +- Key changes: + - Created new file (5907 bytes). + +### components/artifact.test.tsx + +- Lines touched: +95 / -0 +- Key changes: + - components/artifact.test.tsx: Created new file (2 tests using Jest/RTL). + +### .polarity/node_setup.json + +- Lines touched: +1 / -0 +- Key changes: No detailed change summary recorded. + +### components/chat.tsx + +- Lines touched: +25 / -3 +- Key changes: No detailed change summary recorded. + +### components/multimodal-input.tsx + +- Lines touched: +28 / -2 +- Key changes: No detailed change summary recorded. + +### package.json + +- Lines touched: +2 / -2 +- Key changes: No detailed change summary recorded. + +### tsconfig.json + +- Lines touched: +22 / -29 +- Key changes: No detailed change summary recorded. diff --git a/app/(chat)/api/chat/route.test.ts b/app/(chat)/api/chat/route.test.ts new file mode 100644 index 0000000..06bc32a --- /dev/null +++ b/app/(chat)/api/chat/route.test.ts @@ -0,0 +1,229 @@ +import { describe, it, expect, vi, beforeEach } from 'vitest';
