* test(desktop): e2e test for interim assistant message preservation (#65919)
Adds a Playwright E2E test that reproduces the fix from PR #65919 across
all three layers (agent core → tui_gateway → desktop renderer). The mock
inference server is upgraded with a multi-turn scripted response that
exercises several interleaved patterns:
1. text + tool_call → should produce an interim message
2. text + tool_call → another interim message
3. no text + tool_call → NO interim (no visible text alongside tools)
4. text + tool_call → another interim message
5. final answer (stop) → message.complete, different from all interims
Two describe blocks exercise display.interim_assistant_messages both on
(default) and off:
- ON: all interim texts + the final answer visible in the transcript
- OFF: only the final answer visible, all interim texts wiped
Also fixes a footgun: test:e2e now runs `npm run build` as a pretest
hook so the renderer dist/ is always fresh. Previously, running
`npx playwright test` locally would silently load a stale dist/ that
predated renderer fixes — the python backend ran from source (had the
fix) but the renderer was frozen in an old bundle. CI already built
fresh, so the explicit build step there is removed to avoid duplication.
* test(desktop): e2e sidebar states — background dot, subagent, cross-session
Add sidebar-states.spec.ts with three E2E tests exercising the desktop
sidebar's session dot states driven by real gateway events:
1. Background process dot appears during a terminal(background=true)
call and disappears after auto-dismiss; subagent (delegate_task)
runs concurrently; final answer is visible in the transcript.
2. Background dot remains visible while a subagent runs concurrently
(longer sleep 5 background process so the dot is catchable).
3. Cross-session dot transition: start a turn with a background process,
wait for the turn to complete, open a new session, then verify the
original session's dot transitions from 'background running' to
'finished — unread' when the background process exits.
The mock server gains SIDEBAR_SCRIPT and SIDEBAR_CROSS_SCRIPT trigger
keywords that return tool_calls for terminal(background=true) and
delegate_task — the agent executes these for real (real background
process, real subagent), so the tests assert against genuine gateway
events rather than mocked UI state.
Verified: 3 passed (1.2m) under cage headless wlroots.
* test(desktop): e2e tests for tile-unread bug (tab passes, split fails)
Two scenarios for the tile-unread bug where a session that finishes
while visible on-screen gets the green 'finished unread' dot even
though the user is looking right at it.
The unread check in handleTransition (session-states.ts:174) only
compares against $selectedStoredSessionId and ignores $sessionTiles,
so a session visible in a tile gets marked unread even though it's
on screen.
1. TAB (hidden, PASSES): ⌃-click opens the session as a stacked tab
that is NOT visible on screen. The unread dot IS correct here —
the user isn't looking at it.
2. SPLIT (visible, FAILS): drag the session row to the workspace's
right edge to create a side-by-side split tile. Both sessions are
visible on screen. The unread dot is WRONG — the session is visible
in the split tile, so it should not be marked 'unread'. This test
is RED until the fix lands.
Also adds explicit page.screenshot() calls at key assertion points in
sidebar-states.spec.ts so the trace viewer has full-res captures of the
sidebar dot states during the test.
* test(desktop): cover compression and queued stop lifecycle
Add real desktop E2E coverage for session compression continuation and
queue parking after an explicit Stop. Extend the mock server with a
blocking scripted turn and submitted-prompt assertions.
* test(desktop): cover busy composer submit routing
Replace the invalid queued-stop E2E scenario: plain text redirects a busy
turn rather than entering the queue. Add focused submit-routing coverage for
plain text, slash commands, attachments, explicit Stop, and idle submission.
Keep a live session projection from adding its user turn when the latest
persisted row already represents that same inflight prompt. Add real Electron
coverage for fast and cold resume with idle and background-inference sessions.
Exercise the full Electron, gateway, and mock-provider submit path while
same-chat route query tokens churn during session creation. Assert the mock
provider receives the prompt and its streamed response reaches the transcript.
* 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.
Screenshots were catching the app mid-boot at ~92% with the onboarding
Preparing progress bar still visible. waitForAppReady checked for the
composer (textarea/contenteditable) with state:'visible', but Playwright
considers an element visible even when a z-1300+ fixed overlay covers it
(non-zero bounding box, not display:none).
Now waits for the composer to be attached, then polls
document.elementFromPoint at viewport center — if the topmost element is
inside a position:fixed inset:0 overlay, the app isn't ready yet.
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)
