"""Tests for team parameter in training project creation.

This test suite covers all 8 scenarios for team resolution in truss train push:
1. --team PROVIDED: Valid team name, user has access
2. --team PROVIDED: Invalid team name (does not exist)
3. --team NOT PROVIDED: User has multiple teams, no existing project
4. --team NOT PROVIDED: User has multiple teams, existing project in exactly one team
5. --team NOT PROVIDED: User has multiple teams, existing project exists in multiple teams
6. --team NOT PROVIDED: User has exactly one team, no existing project
7. --team NOT PROVIDED: User has exactly one team, existing project matches the team
8. --team NOT PROVIDED: User has exactly one team, existing project exists in different team
