[LucasSantana-Dev]

Summary

• Add comprehensive test suite for auditHandler.ts (26 tests, 77.4% coverage)
• Add comprehensive test suite for memberHandler.ts (21 tests, 95.8% coverage)
• Test all event handlers: message delete/update, ban/unban, channel create/delete, member join/leave
• Cover error handling branches and edge cases

Test Coverage

• auditHandler.ts: 77.4% line coverage (26 tests)
  • Message delete/update events
  • Ban/unban events with audit log integration
  • Channel create/delete events
  • Error handling in all event wrappers

📝 Walkthrough

Walkthrough

Added two comprehensive Jest test suites for Discord event handlers: auditHandler.spec.ts testing audit log event handlers (MessageDelete, MessageUpdate, GuildBanAdd, GuildBanRemove, ChannelCreate, ChannelDelete), and memberHandler.spec.ts testing member event handlers (GuildMemberAdd, GuildMemberRemove). Both suites mock dependencies and validate conditional logging behavior, error handling, and payload structure.
