* nix: add `cage` to devShell
* test(desktop): add pre-filled sessions support
Exports createSandbox, writeMockProviderConfig, writeEnvFile,
buildAppEnv, findElectron, and launchDesktop from fixtures.ts so
specs can compose their own seeded-backend fixtures without duplicating
the sandbox/config/launch logic.
* test(desktop): auto-fail e2e tests on error banner
Adds a shared test fixture (e2e/test.ts) that wraps @playwright/test's
page with an error-banner guard. When any [role="alert"] element
(error notification toast) appears in the DOM during a test, the test
fails with the error message text.
The guard uses:
- A MutationObserver (injected via addInitScript) that watches for
[role="alert"] elements appearing at any point during the test
- A final DOM scan in afterEach for alerts still visible at teardown
- Deduplication so the same error text only fires once
All existing e2e specs updated to import { test, expect } from './test'
instead of '@playwright/test'. No per-spec setup needed — the guard is
auto-installed on every page via the extended fixture.
This catches issues like the "resume failed" error banner that can
appear during session loading — previously the test would pass while
an error toast was silently visible on screen.
* fix(state): parse tool_calls JSON string before re-serializing
_insert_message_rows and append_message both do json.dumps(tool_calls)
to serialize the field for SQLite storage. But when tool_calls arrives
as a JSON string (from import_sessions / export_session, which store it
as TEXT), json.dumps double-encodes it — wrapping the already-serialized
string in quotes and escaping the inner quotes.
When _rows_to_conversation later does json.loads(row['tool_calls']),
the double-encoded string parses back to a plain string (not a list).
_history_to_messages then iterates this string character-by-character,
calling tc.get('function', {}) on each char — 'str' object has no
attribute 'get'.
This was a pre-existing bug (on main), but only triggered by the
import_sessions path (the live agent always passes tool_calls as a
Python list). The e2e error-banner guard caught it via the 'Resume
failed' notification toast.
Fix: in both append_message and _insert_message_rows, parse tool_calls
with json.loads first if it's a string, then re-serialize.
* fix(desktop): exempt boot-failure from error guard
- boot-failure: add allowErrorBanners() beforeEach — these tests
deliberately trigger boot errors, so error toasts are expected
- test.ts: export allowErrorBanners() opt-out + reset flag in afterEach
Reverts the Preparing component changes from b2857110b so the progress bar
turns red (bg-destructive) and the error text shows below it when boot.error
is set, instead of bailing out with an early return null.
The corresponding e2e guard in waitForBootFailure (e2e/fixtures.ts) that
rejected any progress bar in the DOM is dropped — it now waits for the
failure dialog (Retry/Repair/Use local gateway/Connection settings) or the
"Desktop boot failed" toast. The boot-failure.spec.ts header comment is
updated to match.
Verified: tsc clean, vitest boot-failure-reauth (21/21) + boot-failure-overlay
(3/3) pass, npm run build clean, playwright e2e/boot-failure.spec.ts 2/2 pass.
The boot-failure screenshot showed a progress bar because of two bugs:
1. waitForBootFailure matched on "Let's get you setup" (the onboarding
header that mounts from frame 1 during normal boot), so the screenshot
fired at ~86% progress while the Preparing component's progress bar was
still painted.
2. The Preparing component kept rendering the progress bar even after
boot.error was set — it just turned the bar red and appended the error
text below it.
Fixes:
- Preparing bails out (returns null) when boot.error is set, so
BootFailureOverlay (z-1400) owns the screen exclusively.
- applyDesktopBootProgress no longer clobbers a previously-set boot.error
when a late progress event arrives with error: null — failDesktopBoot is
terminal for the boot cycle.
- waitForBootFailure guards against progress bars being visible and matches
on actual failure signals (error toast, Retry/Repair buttons), not the
onboarding header.
- setupDeadBackend now accepts { fakeError: true } which injects
HERMES_DESKTOP_BOOT_FAKE_ERROR to trigger a real boot failure — the
previous dead-provider fixture never actually caused a boot failure
(hermes serve starts fine; the dead endpoint only matters at chat time).
- boot-failure.spec.ts updated to use { fakeError: true }.
Verified: e2e test passes with 0 progress bars in the DOM at screenshot
time (confirmed via DOM inspection), 16/16 vitest tests pass, typecheck
clean.
Adds a full desktop Playwright E2E suite that launches the Electron app
against a mock inference server, exercising the full boot chain:
electron -> hermes serve -> mock provider -> renderer
Includes:
- Mock OpenAI-compatible inference server (mock-server.ts)
- Shared fixtures with sandbox isolation (credentials, HERMES_HOME,
userData, fixed window-state.json for reproducible screenshots)
- Test specs: boot, boot-failure, onboarding, mock-backend-setup, chat,
and packaged-app launch
- Visual regression: expectVisualSnapshot() wraps toHaveScreenshot in
try/catch so diffs are reported without failing the test suite
- CI workflow: xvfb at 1280x1024, baseline cache from main
(--update-snapshots on main, compare on PRs), step summary table with
diff/actual/expected image links, dedicated visual-diffs artifact
- dev:mock script for local fake-provider development
- test:e2e:visual + test:e2e:update-snapshots scripts using cage
- .gitignore: *-snapshots/ (baselines cached in CI, not committed)
