Feishu E2E Test Framework

Local development testing using agent-browser CLI to interact with Feishu web app.

Prerequisites

Feishu web logged in at https://feishu.cn/next/messenger
agent-browser CLI available
OpenClaw locally installed
Feishu bot appid/secret given in chat or in .env
User given bot name which will display in Feishu web UI

Important Notes

Every time you modify extension code, you MUST restart OpenClaw Gateway for changes to take effect.

Restart gateway (required after code changes)

openclaw gateway restart

Check if gateway is running

ps aux | grep openclaw

View gateway logs

tail -f ~/.openclaw/logs/gateway.log

agent-browser Usage

Always use --headed mode so user can see the browser and help with login:

agent-browser --headed --session feishu-test open "https://feishu.cn/next/messenger"

Feishu Web UI Tips

Feishu web has complex UI that makes direct clicking unreliable. Use these strategies:

Use Search (Cmd+K) Instead of Clicking

Clicking on chat list items often misses or selects wrong item. Use global search:

Open search

agent-browser --session feishu-test press "Meta+k"

Type bot name letter by letter

agent-browser --session feishu-test press "o" agent-browser --session feishu-test press "p" agent-browser --session feishu-test press "e" agent-browser --session feishu-test press "n"

Select first result

agent-browser --session feishu-test press "Enter"

Focus Input with "/" Key

After entering a chat, press "/" to focus the message input:

agent-browser --session feishu-test press "/" agent-browser --session feishu-test press "Backspace" # Remove the "/"

Then type your message

Type Characters One by One

The type command often fails with special characters. Use press for each character:

Instead of: agent-browser type "ping"

agent-browser --session feishu-test press "p" agent-browser --session feishu-test press "i" agent-browser --session feishu-test press "n" agent-browser --session feishu-test press "g"

Chinese Characters Do NOT Work

Chinese characters cannot be typed with press command. Use English only:

BAD - Chinese won't render

for char in $(echo "读取文档" | grep -o .); do agent-browser --session feishu-test press "$char" # Will fail silently done

GOOD - Use English

for char in r e a d " " d o c; do agent-browser --session feishu-test press "$char" done

Typing Spaces

Spaces must be quoted as " " :

Type "read doc"

for char in r e a d " " d o c; do agent-browser --session feishu-test press "$char" done

Typing Long Strings Efficiently

Use a for loop to type URLs or long text:

Type a full URL

url="https://feishu.cn/docx/YOUR_DOC_TOKEN" for char in $(echo "$url" | grep -o .); do agent-browser --session feishu-test press "$char" 2>/dev/null || true done

Avoid JS eval on Feishu

Do NOT use eval to set input values - it can break the page:

BAD - will corrupt page

agent-browser eval "document.activeElement.innerText = 'text'"

GOOD - use keyboard input

agent-browser press "t" && agent-browser press "e" ...

Full URLs Work Better Than IDs

When testing document tools, send full URLs rather than just document IDs:

Better - bot recognizes as document link

"https://feishu.cn/docx/YOUR_DOC_TOKEN"

Less reliable - may not trigger tool

"read YOUR_DOC_TOKEN"

Verifying Tool Calls

Log Patterns

Monitor gateway logs to verify tool execution:

tail -f ~/.openclaw/logs/gateway.log

Key log entries:

[feishu] received message from ...
incoming message
[feishu] dispatching to agent
sent to agent
[feishu] added typing indicator reaction
bot is processing
[feishu] deliver called: text=...
agent response
[feishu] dispatch complete
response sent

Verify Tool Usage

Ask bot explicitly to confirm tool usage:

use feishu_doc tool to read YOUR_DOC_TOKEN

Look for confirmation in response like:

"我已经用 Feishu Doc Tool 读过了这个文档"

Common Errors

Permission Error (99991672)

Access denied. One of the following scopes is required: [contact:contact.base:readonly...]

This means bot lacks contact permission. Doesn't affect core messaging but prevents resolving sender names.

Other Log Locations

Error logs

tail -f ~/.openclaw/logs/gateway.err.log

All log files

ls -la ~/.openclaw/logs/

Raw agent session records (tool calls, responses, etc.)

ls ~/.openclaw/agents/main/sessions/

View specific session

cat ~/.openclaw/agents/main/sessions/<session-id>.json

Test Workflow

Start browser: agent-browser --headed --session feishu-test open "https://feishu.cn/next/messenger"
User scans QR to login
Search for bot: Cmd+K → type bot name → Enter
Focus input: press / then Backspace
Type message (English only, letter by letter)
Press Enter to send
Wait 10-20 seconds for response
Take screenshot and check logs to verify

Testing feishu_doc Tool

1. Focus input

agent-browser --session feishu-test press "/" &&
agent-browser --session feishu-test press "Backspace"

2. Type full doc URL

url="https://feishu.cn/docx/YOUR_DOC_ID" for char in $(echo "$url" | grep -o .); do agent-browser --session feishu-test press "$char" 2>/dev/null || true done

3. Send
