The previous implementation used L.heatLayer's minOpacity which only
controlled the opacity of the coolest (blue) gradient stops. Now sets
CSS opacity on the canvas element directly, affecting all gradient
colors uniformly. Closes#119 properly.
Backend-only change: ~1 min (unit tests, skip Playwright/coverage)
Frontend-only change: ~2-5 min (E2E + coverage, skip backend suite)
Both changed: full suite (~14 min)
CI/test infra changed: full suite (safety net)
Detects changed files via git diff HEAD~1, runs appropriate suite.
The page.evaluate() calls corrupting localStorage and firing fake events
caused page error-reloads, losing accumulated coverage. Reverting to
the 42% version which was the actual high water mark.
- Full test file list with all 12+ test files
- Feature development workflow: write code → write tests → run locally → push
- Playwright defaults to localhost:3000, NEVER prod
- Coverage infrastructure explained (Istanbul instrument → Playwright → nyc)
- ARM testing notes (basic tests work, heavy coverage use CI)
- 4 new pitfalls from today's session
Exercise every major code path across all frontend files:
app.js: all routes, bad routes, hashchange, theme toggle x4,
hamburger menu, favorites dropdown, global search, Ctrl+K,
apiPerf(), timeAgo/truncate/routeTypeName utils
nodes.js: sort every column (both directions), every role tab,
every status filter, cycle all Last Heard options, click rows
for side pane, navigate to detail page, copy URL, show all
paths, node analytics day buttons (1/7/30/365), scroll target
packets.js: 12 filter expressions including bad ones, cycle all
time windows, group by hash toggle, My Nodes toggle, observer
menu, type filter menu, hash input, node filter, observer sort,
column toggle menu, hex hash toggle, pause button, resize handle,
deep-link to packet hash
map.js: all role checkboxes toggle, clusters/heatmap/neighbors/
hash labels toggles, cycle Last Heard, status filter buttons,
jump buttons, markers, zoom controls, dark mode tile swap
analytics.js: all 9 tabs clicked, deep-link to each tab via URL,
observer selector on topology, navigate rows on collisions/
subpaths, sortable headers on nodes tab, region filter
customize.js: all 5 tabs, all preset themes, branding text inputs,
theme color inputs, node color inputs, type color inputs, reset
buttons, home tab fields (hero, journey steps, checklist, links),
export tab, reset preview/user theme
live.js: VCR pause/speed/missed/prompt buttons, all visualization
toggles (heat/ghost/realistic/favorites/matrix/rain), audio
toggle + BPM slider, timeline click, resize event
channels.js: click rows, navigate to specific channel
observers.js: click rows, navigate to detail, cycle days select
traces.js: click rows
perf.js: refresh + reset buttons
home.js: both chooser paths, search + suggest, my-node cards,
health/packets buttons, remove buttons, toggle level, timeline
Also exercises packet-filter parser and region-filter directly.
- Install nyc for Istanbul instrumentation
- Add scripts/instrument-frontend.sh to instrument public/*.js
- Add scripts/collect-frontend-coverage.js to extract window.__coverage__
- Add scripts/combined-coverage.sh for combined server+frontend coverage
- Make server.js serve public-instrumented/ when COVERAGE=1 is set
- Add test:full-coverage npm script
- Add public-instrumented/ and .nyc_output/ to .gitignore
Tests now run in the test job, not after deploy. Spins up server.js
on port 13581, runs Playwright against it, kills it after.
If E2E fails, deploy is blocked — broken code never reaches prod.
BASE_URL env var makes the test configurable.
test-server-routes.js destructures { cache, pktStore, db } but these
weren't in module.exports. Also adds require.main guard so server
doesn't listen when imported by tests.
8 smoke tests against prod after deployment completes.
Uses Playwright bundled Chromium on x86 runner.
Falls back to CHROMIUM_PATH env var for other architectures.
Proof of concept: bare Playwright (not @playwright/test) running 8 critical
flow tests against analyzer.00id.net:
- Home page, nodes, map, packets, node detail, theme customizer, dark mode, analytics
- Uses system Chromium on ARM (Playwright bundled binary doesn't work on musl)
- Not added to test-all.sh or CI yet — POC only
- Run with: node test-e2e-playwright.js
Badges show: 'tests: 844/844 passed' and 'coverage: 76%'
Updated automatically by CI after each run via .badges/ JSON files.
Color: green >80%, yellow >60%, red <60%.

Golden fixture tests need updating to match correct output.
Replace duplicated function definitions in server.js with imports from
server-helpers.js. Functions replaced: loadConfigFile, loadThemeFile,
buildHealthConfig, getHealthMs, isHashSizeFlipFlop, computeContentHash,
geoDist, deriveHashtagChannelKey, buildBreakdown, updateHashSizeForPacket,
rebuildHashSizeMap, requireApiKey, CONFIG_PATHS, THEME_PATHS.
disambiguateHops kept in server.js due to behavioral differences in the
distance sanity check (server version nulls lat/lon on unreliable hops
and adds ambiguous field in output mapping).
server.js: 3201 → 3001 lines (-200 lines, -224 deletions/+24 insertions)
All tests pass (unit, e2e, frontend).
Added test job that runs unit tests + integration tests + coverage
before deploy. Deploy job depends on test job passing.
If any test fails, deploy is blocked.
