How to Test a Discord Bot: Proof It Works (Checklist)

Testing a Discord bot is about proof. Not “it ran once”—proof that commands work, events fire, permissions are correct, and the deployed bot stays online and observable.
TL;DR
- Create a private test guild with a #bot-sandbox channel and #bot-logs channel.
- Verify permissions + intents before you test features.
- Test commands: happy path, invalid input, permission denied, rate limits.
- Test events: join/leave, message, reaction, scheduled jobs.
- Prove deploy: uptime + logs + “version” command so you know what’s running.
Set up a test guild (fast)
Don’t test in production channels first. Create a small test space where you can spam commands without annoying anyone:
- Guild: a private test guild (or a private category in your guild).
- Channels:
#bot-sandbox(commands) and#bot-logs(errors + audit). - Roles: one “Admin” role and one “Member” role to validate permission boundaries.
Permissions + intents checklist
Most “my bot is broken” bugs are really permission issues. Validate these first:
- Bot role placement: the bot role is above the roles it needs to manage.
- Channel permissions: bot can view + send + embed links in the channels you test.
- App permissions: requested scopes/permissions match what the bot actually does.
If you’re stuck, start with common permission errors and why bots can’t see channels.
Command test checklist (copy/paste)
# Commands (run in #bot-sandbox)
✅ Happy path:
- /help
- /ping
- /status (or /about)
✅ Invalid input:
- Missing required options
- Invalid option value
- Too-long input
✅ Permissions:
- Run admin commands as Member (should fail safely)
- Run member commands as Admin (should work)
✅ Rate limits:
- Run a command 10x quickly (should not spam / should back off)
✅ Error handling:
- Force an error path (bad ID, missing channel)
- Ensure it logs to #bot-logs with a helpful messageEvent test checklist
Next, prove the bot responds to real Discord events (not just slash commands):
- Member join: welcome message (and no duplicate spam on rejoin).
- Message create: keyword/AI responses only where intended (avoid replying everywhere).
- Reactions: reaction roles or acknowledgements work (and have safety limits).
- Scheduled tasks: daily/weekly jobs run once (no duplication after restarts).
If your bot “stops responding”, see this troubleshooting guide.
Failure modes: rate limits, retries, and safe defaults
A bot that works once isn’t a bot—it’s a demo. Production bots need safe behavior under load and failure:
- Rate limiting: cap responses per channel/minute to avoid spam.
- Retries: retry transient API failures with backoff (but don’t retry forever).
- Idempotency: event handlers should not double-post on reconnects.
Deploy proof: what “working” actually means
Here’s the simplest definition of done:
- Version proof: a
/versionor/aboutcommand prints build/version info. - Observability: errors go to
#bot-logs(no tokens, no sensitive data). - Uptime: bot stays online across restarts and deploys.
This “proof first” approach is a big part of how we’re improving reliability in VibeCord. If you want the behind-the-scenes view, read how we improve AI bot quality.
Monitoring (minimum viable)
- Alerts when the bot disconnects
- Error rate spikes
- Command latency (p95)
FAQ
Why does my bot work locally but not in Discord?
Usually: permissions, missing intents, incorrect scopes, or the bot is in the wrong channels. Start with permission errors.
What’s the fastest “smoke test”?
/ping, /help, one event (member join), and one log entry to #bot-logs. If any of those fail, fix that before adding features.
