test(sdk-core): add comprehensive tests for collection avatar/banner

aspiers · Claude Code · aspiers · commit 320b428a073b · 2026-01-24T18:21:38.000+13:00
Without this patch, the collection avatar and banner feature (added in
beta.7) lacked comprehensive test coverage and documentation examples
showing how to use these visual branding features.

This is a problem because users need clear examples showing how to:
- Create collections with avatar/banner images using Blobs or URIs
- Update collection images (add, modify, remove, or preserve)
- Use avatar/banner in both collections and projects

This patch solves the problem by adding:

- 7 new tests for avatar/banner CRUD operations (create, update, remove)
- Tests for both Blob uploads and URI string references
- Tests for preserving images during partial updates
- Changeset documenting the new test coverage
- Update spec marking Change 3 (Collection Avatar and Banner) complete

Tests added:
- Create collection with avatar/banner (Blob)
- Create collection with avatar/banner (URI strings)
- Create project with avatar/banner
- Update collection avatar/banner (Blob)
- Update collection avatar/banner (URI strings)
- Remove avatar/banner when set to null
- Preserve avatar/banner when not updating them

All tests passing: 632 tests in sdk-core, 136 in sdk-react

Spec: specs/lexicon-sync/v0.10.0-beta.4-v0.10.0-beta.11.md (Change 3)

+Add comprehensive documentation and tests for collection avatar and banner images
+
+Collections and projects now support avatar (thumbnail/icon) and banner (header/cover) images. Images can be provided as
+Blobs for upload or as URI strings for external references.
+
+**What's Included:**
+
+- Comprehensive JSDoc documentation for `HypercertCollection` type explaining avatar and banner usage
+- Tests for creating collections with avatar/banner using both Blobs and URI strings
+- Tests for updating collection images (add, update, remove, preserve)
+- Examples showing avatar/banner in collections and projects
