Pull request overview
This PR implements a comprehensive automated testing infrastructure to detect display, accessibility, and structural issues across 50+ ObjectUI component renderers. The test suite includes specialized utilities for validation and covers all major component categories.
Changes:
- Added test utilities (
test-utils.tsx) with automated accessibility, DOM structure, and display issue detection - Implemented 150 tests across 5 test files covering basic, form, layout, feedback/overlay, and complex components
- Created documentation (
TESTING.md,ISSUES_FOUND.md,README.md) describing the testing approach and findings

There was a problem hiding this comment.
The logic for checking form label association is incomplete. The presence of an id attribute on an input doesn't guarantee it's properly labeled - there must be a corresponding <label for="id"> element or the input must be wrapped in a label. This check will miss form inputs that have an ID but no associated label element, creating false negatives in accessibility testing.

The duplicate list items detection logic has a flaw. It checks if contents.indexOf(item) !== index, but this only finds the first occurrence of each duplicate, not all duplicates. For a list with items ["A", "B", "A", "A"], this would only flag indices 2 and 3, missing that index 0 is also a duplicate. A more accurate check would be to count occurrences or use a Set to track which content values appear more than once.

| **Coverage:** 49 tests |
There was a problem hiding this comment.
The test count stated as "49 tests" is incorrect. The actual count for form-renderers.test.tsx is 32 tests (matching the PR description). This discrepancy should be corrected to avoid confusion.
