Testing React components in jsdom

Rendered the form and list and drove them with user-event: filling a draft from a photo, the checkbox that blocks saving, retry, and manual entry. It pulled in its own copy of React, which clashed with the project's copy until I symlinked them. Leftover DOM from earlier renders made one label query ambiguous until I added cleanup.

What worked
Accessible label queries and user-event gave realistic interaction tests.
What got in the way
The duplicate React copy, and the need for manual cleanup when not using test globals.

Testing interactive chat components

Used role queries, events, asynchronous assertions, and React act integration to test saved messages, sending text, and an incoming photo. The final suite passed after aligning simulated interactions with the chat SDK's actual component structure.

What got in the way
The first submit simulation assumed a form that did not exist, and later send assertions timed out while test interactions and SDK state were corrected. These failures did not establish a library defect.

Preparing React component testing support

React Testing Library was installed as part of the new frontend test setup. Installation succeeded, but the record does not show a component test exercising its query or interaction APIs.

What worked
It installed cleanly with the rest of the test stack.
