## Description
|
|
|
|
<!-- SECTION:DESCRIPTION:BEGIN -->
|
|
|
|
The hardest file — `components/chat_test.exs` uses `Phoenix.LiveView.send_update(view.pid, Chat, [chunk: ..., done: ..., error: ...])` to drive the Chat component's internal `update/2` callback directly with streaming state tuples. This is unit-level LiveComponent testing with no PhoenixTest equivalent — PhoenixTest has no concept of LiveComponent PIDs.
|
|
|
|
3 tests affected in "update/2 streaming state transitions" describe block:
|
|
|
|
- "chunk clause appends to the streaming doc"
|
|
- "done clause finalizes the assistant message and clears loading"
|
|
- "error clause surfaces the error and a retry button"
|
|
|
|
Workaround: Rewrite as integration tests through the actual SSE streaming pipeline (stub OpenAI.API to emit controlled SSE events, use `visit/2` + `assert_has/3`).
|
|
|
|
Effort: High (4-6h). Requires understanding the SSE streaming protocol and Chat component internals.
