Regression Testing

Session Setup

bun run stop

cd /Users/smcllns/Projects/atomic-editor && bun run dev > /tmp/atomic-dev.log 2>&1 &

sleep 5 && curl -s http://localhost:7777/state

If no window is returned, the app launched but no file is open — that's expected at this point. If the curl fails entirely, check /tmp/atomic-dev.log for startup errors.

Regression Flows

Run in order. Each flow verifies state via /state after each action.

Flow 1 — App Launch

curl -s http://localhost:7777/state

Pass: Returns no window (server is up, no file open yet).

Flow 2 — Open File

curl -s "http://localhost:7777/open?path=$(python3 -c 'import urllib.parse; print(urllib.parse.quote("/Users/smcllns/Projects/atomic-editor/test.md"))')"

sleep 1 && curl -s http://localhost:7777/state

Pass: {dirty: false, mode: "wysiwyg", filePath: ".../test.md"}

Flow 3 — Dirty on Edit (wysiwyg)

curl -s http://localhost:7777/dirty && sleep 0.5 && curl -s http://localhost:7777/state

Pass: dirty: true

Flow 4 — Save Clears Dirty

curl -s http://localhost:7777/save && sleep 0.5 && curl -s http://localhost:7777/state

Pass: dirty: false. Confirm file was written:

ls -la /Users/smcllns/Projects/atomic-editor/test.md

Flow 5 — Dirty Again + Save via Second Edit

curl -s http://localhost:7777/dirty && sleep 0.5 && curl -s http://localhost:7777/state

Pass: dirty: true

curl -s http://localhost:7777/save && sleep 0.5 && curl -s http://localhost:7777/state

Pass: dirty: false

Flow 6 — Toggle to Raw Mode

curl -s http://localhost:7777/toggle && sleep 0.5 && curl -s http://localhost:7777/state

Pass: {dirty: false, mode: "raw"}

Flow 7 — Dirty on Edit (raw)

curl -s http://localhost:7777/dirty && sleep 0.5 && curl -s http://localhost:7777/state

Pass: dirty: true

Flow 8 — Toggle Back (no spurious dirty)

Save first, then toggle back:

curl -s http://localhost:7777/save && sleep 0.5

curl -s http://localhost:7777/toggle && sleep 1 && curl -s http://localhost:7777/state

Pass: {dirty: false, mode: "wysiwyg"} — spurious dirty on toggle was a historical bug; any dirty: true here is a regression.

Flow 9 — md Shell Function (prod build only)

Requires a current canary build. Run after bun run build:

md /Users/smcllns/Projects/atomic-editor/test.md
sleep 2

Pass: Atomic Editor-canary opens with test.md loaded.

Cleanup

test.md is modified by save tests — restore it:

git checkout /Users/smcllns/Projects/atomic-editor/test.md

Stop the dev server:

bun run stop

Pass Criteria

All flows pass when:

• /state returns expected values at each step
• No dirty: true after toggle back to wysiwyg (Flow 8)
• md opens the canary build explicitly (Flow 9)

Any unexpected state = regression. Stop and report the failing flow with observed vs expected /state output.
