Cherry Studio PR Test

Automated PR testing workflow for Cherry Studio. Checks out a PR, launches the Electron app with Chrome DevTools Protocol, connects agent-browser, and runs interactive UI + code review tests.

Prerequisites

  • gh
    CLI installed and authenticated
  • agent-browser
    installed (for CDP-based UI testing)
  • pnpm
    installed with project dependencies (
    pnpm install
    )

Constraints

  • Always kill existing Cherry Studio processes before launching a new instance.
  • Never leave debug processes running after testing completes.
  • Always switch back to the default branch after testing.
  • Always show the test report to the user before posting it.

Arguments

$ARGUMENTS
may contain:

  • A PR number (e.g.,
    13955
    )
  • A PR URL (e.g.,
    https://github.com/CherryHQ/cherry-studio/pull/13955
    )
  • Keywords like "latest", "recent" to pick a recent PR
  • Empty — list recent PRs and let the user choose

Workflow

Phase 1: Select & Checkout PR

  1. If no PR number given, list recent open PRs:
    gh pr list --repo CherryHQ/cherry-studio --state open --limit 10 \
      --json number,title,author,createdAt,headRefName,changedFiles \
      --template '{{range .}}#{{.number}} | {{.title}} | by {{.author.login}} | files: {{.changedFiles}}
    {{end}}'
    
  2. Ask the user to pick one (or auto-pick if "latest"/"recent").
  3. View PR details to understand what changed:
    gh pr view <NUMBER> --json title,body,headRefName,files
    
  4. Checkout the PR branch:
    gh pr checkout <NUMBER>
    
  5. Read the key changed files to understand the scope of changes.

Phase 2+3: Static Analysis & Launch App (parallel)

Static analysis and app launch are independent — run them in parallel to save time.

Static Analysis (can run while app is starting)

  1. TypeScript typecheck (catch type errors early):
    pnpm typecheck 2>&1 | grep -E "error TS|exited with code"
    
  2. Review blocked files: Check if the PR modifies files with
    @deprecated
    /
    V2 DATA&UI REFACTORING
    headers. These files are blocked for feature changes until v2.0.0.
  3. Scan for common issues:
    • Hardcoded strings (should use i18n)
    • console.log
      usage (should use
      loggerService
      )
    • Missing type annotations on new public interfaces

Record all findings for the final report.

Launch App

  1. Kill any existing Cherry Studio processes (graceful SIGTERM first):

    pkill -f "cherry-studio.*Electron" 2>/dev/null
    pkill -f "electron-vite" 2>/dev/null
    lsof -ti :9222 | xargs kill 2>/dev/null
    lsof -ti :5173 | xargs kill 2>/dev/null
    sleep 3
    # Escalate to SIGKILL only if processes remain
    lsof -ti :9222 | xargs kill -9 2>/dev/null
    lsof -ti :5173 | xargs kill -9 2>/dev/null
    
  2. Start in debug mode (includes

    --remote-debugging-port=9222
    ):

    nohup pnpm debug > /tmp/cherry-debug.log 2>&1 &
    
  3. Wait for startup (typically 20-30s):

    for i in $(seq 1 30); do
      lsof -i :9222 2>/dev/null | grep LISTEN && break
      sleep 2
    done
    

Phase 4: Connect agent-browser

  1. Connect:

    agent-browser connect 9222
    

    If

    connect
    fails, fall back to websocket URL from logs:

    WS_URL=$(grep "DevTools listening" /tmp/cherry-debug.log | sed 's/.*ws:/ws:/')
    agent-browser --cdp "$WS_URL" navigate http://localhost:5173
    
  2. Verify connection and identify the main page:

    agent-browser tab
    

    You should see the main Cherry Studio page at

    http://localhost:5173/
    . If multiple tabs are listed, use
    agent-browser tab <N>
    to select the main one.

  3. Handle first-launch scenarios:

    • V2 Data Migration Wizard: On the v2 branch (or fresh dev data), the app may show a migration wizard (
      /migrationV2.html
      ) before the main UI. Click through: 介绍(下一步) → 备份(我已备份,开始迁移) → 迁移(确定) → 完成(重启应用). After "重启应用", kill and relaunch the app (the restart button doesn't work in dev mode).
    • Splash screen: Wait up to 30s for the splash to dismiss.
  4. Create screenshot directory for this PR:

    mkdir -p /tmp/pr-<NUMBER>
    

    Use this directory for all screenshots:

    /tmp/pr-<NUMBER>/<descriptive-name>.png

Phase 5: Interactive UI Testing

Based on the PR's changed files, navigate to the relevant pages and test. Use your judgement to decide what to test — the PR description and changed files should guide your testing strategy.

General Approach

  1. Take a screenshot of the current state
  2. Use
    agent-browser snapshot -i
    to discover interactive elements
  3. Interact with elements (click, fill, drag, etc.)
  4. Screenshot and verify the result
  5. Verify state changes if relevant (via
    agent-browser eval
    )

Key Testing Points

  • UI renders correctly: New components appear in the right place
  • Interactions work: Toggles, inputs, buttons all function
  • State persistence: Changes survive across page navigations
  • Theme compatibility: Test in both light and dark modes
  • Layout modes: If sidebar/layout is involved, test at different sizes
  • i18n: Switch language and verify new strings appear correctly
  • Edge cases: Boundary conditions, rapid toggling, empty states

Phase 6: Cleanup

After testing:

  1. Kill all Cherry Studio processes (graceful SIGTERM first):

    pkill -f "cherry-studio.*Electron" 2>/dev/null
    pkill -f "electron-vite" 2>/dev/null
    lsof -ti :9222 | xargs kill 2>/dev/null
    lsof -ti :5173 | xargs kill 2>/dev/null
    sleep 3
    lsof -ti :9222 | xargs kill -9 2>/dev/null
    lsof -ti :5173 | xargs kill -9 2>/dev/null
    
  2. Switch back to the default branch:

    default_branch=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')
    git checkout "${default_branch:-main}"
    

Phase 7: Test Report

Generate a structured report with screenshots. Save the report as

/tmp/pr-<NUMBER>/report.md
alongside the screenshots.

Troubleshooting

Port 9222 not listening after startup

The

pnpm debug
script passes
--remote-debugging-port=9222
to Electron. If not working:

  • Check logs:
    tail -50 /tmp/cherry-debug.log
  • Kill by port:
    lsof -ti :9222 | xargs kill -9
  • Verify electron-vite is running:
    ps aux | grep electron-vite

agent-browser connect fails

Use direct websocket URL:

WS_URL=$(grep "DevTools listening" /tmp/cherry-debug.log | grep 9222 | sed 's/.*\(ws:\/\/[^ ]*\)/\1/')
agent-browser --cdp "$WS_URL" tab

agent-browser target jumps to wrong page

Electron apps have multiple CDP targets (main window + webviews for mini-apps). If

agent-browser
connects to a webview instead of the main page:

# List all targets
agent-browser tab
# Switch to the main page (usually tab 0, URL contains localhost:5173)
agent-browser tab 0

After opening/closing mini-apps, always verify you're on the right target with

agent-browser tab
.

V2 Data Migration Wizard

On the v2 branch, the app may show a data migration wizard on first launch. This is not a bug — it's expected when dev data hasn't been migrated yet. Click through the wizard steps, then restart the app manually (kill + relaunch). The wizard only appears once; subsequent launches go straight to the main UI.

App stuck on splash screen

Wait longer (up to 30s on first launch). The app needs to:

  • Build and serve renderer via Vite dev server (port 5173)
  • Run database migrations
  • Initialize services (MCP, etc.)

Empty CDP target list

After connecting, if

agent-browser tab
shows only
about:blank
:

agent-browser navigate http://localhost:5173
sleep 10
agent-browser tab
