Overview

Create an integration test or manual test plan to verify graceful shutdown behavior, particularly in Docker environments.

Current State

Graceful shutdown is implemented and working:

SIGINT/SIGTERM handlers wired
Bot stops accepting updates
Worker pool shuts down cleanly
Idempotent shutdown flag prevents double-execution

What's Needed

Option 1: Automated Integration Test

Create test that:
- Starts the bot
- Sends SIGTERM
- Verifies clean exit
- Verifies no hanging processes
- Verifies proper exit codes

Option 2: Manual Test Plan

Document manual testing steps in README or TESTING.md:
- How to test with docker stop
- How to test with Ctrl+C locally
- Expected behavior and timing
- How to verify clean shutdown

Docker-Specific Considerations

Test with Docker compose stop
Verify graceful period is respected (default 10s)
Document any --stop-timeout requirements if needed

Acceptance Criteria

Either automated test exists OR manual test plan is documented
Test covers both SIGINT and SIGTERM
Docker-specific scenarios covered
Exit codes verified (0 for clean, 1 for error)

Priority: Low
Estimated Effort: Small
Related: Issue #15 (Smart Worker Queue Drain) may affect shutdown behavior

Completed ✅

Added graceful shutdown testing implementation:

Code Changes

Added timeout to (5s) to prevent hanging during shutdown
Clear healthcheck interval during graceful shutdown
Fixed potential race condition in shutdown handler

Testing

Created with 3 integration tests:
- SIGTERM handling
- SIGINT handling
- Multiple signals idempotency
Tests skip automatically (no TOKEN needed for skip)
Tests account for Windows/Unix signal differences

Documentation

Created comprehensive guide with:
- Manual testing procedures
- Docker testing scenarios
- Exit code documentation
- Production deployment checklist

Notes

Automated tests require Unix environment (CI) due to Windows signal handling differences
Manual testing guide covers Windows scenarios
All 66 regular tests passing + 3 shutdown tests (skipped in dev)

See commit 38c9ae1
