* ⚡ Build the frontend bundle once for all E2E suites Merge tests-integration, tests-composable-suite and tests-plugin-api-suite into one "CI: E2E" workflow. Each of the three ran its own full frontend/scripts/build on every PR, so one PR paid the build three times. The new build-bundle job restores actions/cache key frontend-bundle-<sha>, runs frontend/scripts/build only on a miss and saves the key before the job ends. The integration shards, the composable suite and the mocked Plugin API suite now all need build-bundle and restore the same key with fail-on-cache-miss, so none of them builds. A workflow re-run of the same SHA reuses the cached bundle instead of rebuilding it. Triggers become the union of the previous paths (frontend, common, render-wasm, plugins): the bundle embeds the built plugins, so a plugins change runs the whole set. workflow_dispatch keeps running the integration job only, as before. Job names are kept identical on purpose: they are the GitHub check contexts and branch protection may match them by name. Docs: new mem:frontend/e2e-ci-workflow records the build-once contract, referenced from mem:frontend/core and mem:frontend/testing; the composable memory and both suite READMEs are updated. AI-assisted-by: deepseek-v4.1-flash * 🐛 Fix mocked plugin suites crashing without frontend deps The mocked CI drivers shelled out to frontend/scripts/e2e-server.js, which imports express from frontend/node_modules. CI jobs install only plugins/ deps, so the import failed with ERR_MODULE_NOT_FOUND and the run timed out waiting for localhost:3000. Serve the prebuilt bundle with a zero-dependency static server built into each driver (ci/static-server.ts, kept in sync in both suites) plus node:test coverage for it.

Frontend Testing and Live Verification
Frontend validation: CLJS + React/Rumext + RxJS/Potok; SCSS modules; shared CLJC from common/.
Unit tests
READ mem:testing FIRST — it defines the execution discipline (no piping, tee to file, preferred commands) that applies to all CLJS/JS test runs.
Frontend unit tests live under frontend/test/frontend_tests/ and use cljs.test. They should be deterministic, avoid DOM/UI integration where possible, and mock side effects such as RPC, storage, timers, or network access.
From frontend/:
- Full unit test run (always builds, suppressed output):
pnpm run test:quiet. - Full unit test run (always builds, build output visible):
pnpm run test. - Focus a frontend CLJS test namespace:
pnpm run test:quiet -- --focus frontend-tests.logic.components-and-tokens. - Focus one frontend CLJS test var:
pnpm run test:quiet -- --focus frontend-tests.logic.components-and-tokens/change-spacing-token-in-main-updates-copy-layout. - Quiet
app.*logging during a run: append--log-level warn(ortrace|debug|info|warn|error). - Build test target only (no run):
pnpm run build:test. - After
build:testhas been run, run the compiled runner directly:node target/tests/test.js [--focus ...] [--log-level ...]. - Watch tests:
pnpm run watch:test.
New frontend test namespaces must be required/listed in frontend_tests/runner.cljs; new vars in existing namespaces need no runner change.
Playwright integration tests
Do not add, modify, or run Playwright integration tests under frontend/playwright unless explicitly asked. When explicitly asked, use pnpm run test:e2e or pnpm run test:e2e --grep "pattern" from frontend/; ensure dependencies are installed through ./scripts/setup if the environment is not prepared.
Integration tests fake backend behavior by intercepting network/websocket traffic, so every RPC or websocket the page needs must be mocked. Use existing Page Object Models:
BasePage.mockRPCintercepts RPC calls and already prefixes/api/rpc/command/; pass command names such asget-profile, not full URLs.- Workspace or other websocket-using pages should extend/use
BaseWebSocketPage, initialize websocket mocks before each test, and mock/ws/notificationswith the provided helpers. - Prefer common locators/actions in POMs; ad-hoc locators can stay in a single test.
Locator priority should follow user-facing semantics: getByRole, getByLabel, getByPlaceholder, getByText, then semantic alternatives such as alt/title, with getByTestId as the last resort. Name tests from the user's perspective and prefer positive, single-purpose assertions.
CI (E2E)
.github/workflows/tests-e2e.yml runs the integration specs, the composable component suite, and the mocked Plugin API suite from one workflow that builds the frontend bundle once per SHA. Before adding a job that needs the bundle, read mem:frontend/e2e-ci-workflow (build-once contract, cache key, stable check names).
Live browser verification
Because CLJC compiles to both JVM and CLJS, JVM/common tests can miss frontend-only state caused by browser runtime, WASM modifier math, or real pointer events. Use mem:frontend/cljs-repl to inspect live app state and mem:frontend/playwright-gestures when real input is needed.
For stale hot reload or failed CLJ/CLJC/CLJS source builds, read mem:frontend/compile-diagnostics. For Internal Error pages or delayed runtime crashes after automation/API actions, read mem:frontend/handling-crashes. Translation .po changes are bundled into index.html and require a browser refresh.
