Covers the one leg the credential-free mock suite cannot fake: a file attached through the UI's Code Environment target must land in the live Code API, get delivered into the sandbox, and stay readable across turns. - fake-model: E2E_EXEC_UPLOADED:/E2E_EXEC_PERSIST: markers emit real bash_tool calls through the production tool pipeline (the sandbox surface stateful agents register; execute_code stays host-wired and never appears in the tool registry), plus an env-gated dump of each run's advertised tools for future spec authoring - spec: attach uploads a CSV to the Code API, turn 1 reads it back from /mnt/data and drops a proof file no upload contained, turn 2 (sent without an attachment) reads both — only possible when the run reuses the same stateful runtime session - e2e config: agents capabilities gain stateful_code_sessions, and the mock profile pins CHECK_BALANCE=false so a developer's local .env can never fail every send with zero-balance users - skips unless LIBRECHAT_CODE_BASEURL is provided (kept out of CI) |

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.
