The no-spec branch of `useApplyModelSpecEffects` (added in #11796) reset `ephemeralAgentByConvoId` to null on every `newConversation` call when model specs are configured. On in-place model/endpoint switches (modular chat, same conversation or new-chat draft), BadgeRowContext never refills from localStorage — its init effect only re-runs when the storage suffix or spec changes — so the MCP selection (and tool toggles) were silently dropped from subsequent request payloads while the MCP badge kept displaying them. Reset now only happens on context transitions (leaving a spec, or moving to a different conversation key), where a BadgeRowContext refill is guaranteed; in-place non-spec switches preserve the ephemeral agent. - Gate the no-spec reset on `prevSpecName` / `prevConvoId`, passed from `newConversation` via a snapshot read of the pre-switch conversation - Add jest coverage for all five branches of the no-spec path - Add e2e spec asserting `ephemeralAgent.mcp` stays in the chat payload after a new-chat model switch and after regenerate on a switched conversation (verified failing before the fix, passing after) - Add non-spec "Mock Provider D" endpoint to the e2e config so tests can switch between two real ephemeral endpoints; widen `MockEndpoint` type |

LibreChat e2e
The mock e2e profile is the safest default for generated tests. It starts LibreChat with e2e/config/librechat.e2e.yaml, injects an in-process fake LLM (via LIBRECHAT_TEST_RUN_HOOK), creates an authenticated e2e user, and avoids real provider credentials.
Recording Tests
Use Playwright codegen when you want to turn an exploratory browser session into a draft test:
npm run e2e:record
That command builds the app, starts the LibreChat test server (with an in-process fake LLM) when needed, writes e2e/storageState.json, and opens Playwright codegen at /c/new. The npm script uses http://localhost:3333 so it does not collide with a normal dev server on 3080. Raw recordings are written to e2e/recordings/ and ignored by git.
For a real local LibreChat config instead of the mock profile:
npm run e2e:record:local
Useful direct options:
node e2e/setup/record.js --url=http://localhost:3080/c/new
node e2e/setup/record.js --profile=local --no-output
node e2e/setup/record.js --auth-only
node e2e/setup/record.js --output=e2e/recordings/settings-draft.spec.ts
LLM-Assisted Loop
- Start
npm run e2e:record. - Let the LLM use Computer Use to operate the headed Playwright browser.
- Stop codegen after the workflow is captured.
- Move the useful parts from
e2e/recordings/into a committed spec undere2e/specs/mock/. - Replace brittle generated selectors with role, label, text, or
data-testidlocators. - Add assertions that prove the behavior, not just the clicked path.
- Run the finished spec with
npm run e2e:mock -- <spec name>.
Generated recordings are a draft, not the final test. The committed version should use the shared helpers in e2e/specs/mock/helpers.ts where possible, wait on network or visible UI state instead of fixed sleeps, and keep test data deterministic.
