P0-S1-002: Establish Test Infrastructure

[Reg-Kris]

User Story

As a developer, I need a working test suite so I can ensure code quality and prevent regressions.

Current State

• Test suite shows 0-8 out of 42 tests passing
• Multiple testing frameworks partially configured
• No consistent testing strategy across services
• CI/CD pipeline not running tests automatically

Acceptance Criteria

• Unit test framework setup for all Python services (pytest)
• Frontend testing setup with React Testing Library/Vitest
• Integration tests for critical API endpoints
• E2E tests for authentication flow
• Test database isolation and cleanup
• CI/CD pipeline running tests automatically
• At least 50% of existing tests passing
• Test coverage reporting enabled

Branch Name

feat/test-infrastructure

Story Points

13 (Large effort involving multiple services and frameworks)

Dependencies

• All services must be buildable and startable
• CI/CD pipeline access and configuration
