🤖 Okteto AI Agent PR

Summary

This PR upgrades the entire application stack to the latest stable versions of Python, all dependencies, and infrastructure components. It also adds a comprehensive pytest-based test suite with 15 tests covering all application functionality.

Changes Made

🐍 Python & Application Dependencies

• Python: 3.9 → 3.13.11 ✅
• Django: 4.2 → 5.1.4 ✅
• Celery: 5.3.1 → 5.4.0 ✅
• Django REST Framework: 3.14.0 → 3.15.2 ✅

• Redis: 6 → 7.4.7 (Alpine) ✅
• RabbitMQ: 3.6.0 → 4.0.9 (Alpine) ✅

🧪 Testing (New!)

Added comprehensive pytest test suite:

• 15 tests organized into 5 logical categories
• Test coverage for:
  • ✅ API endpoints (3 tests)
  • ✅ Job creation (2 tests)
  • ✅ Job processing (3 tests)
  • ✅ Edge cases (3 tests)
  • ✅ Input validation (2 tests)
  • ✅ Integration tests (2 tests)
• Pytest fixtures for reusable test components
• Proper service discovery using Kubernetes DNS
• Integrated with Okteto test framework

Test Dependencies Added:

• pytest 8.3.4
• pytest-xdist 3.6.1 (parallel execution support)
• requests 2.32.3

🐛 Bug Fixes

• Critical bug fixed in myproject/models.py: Job model was hardcoded to always execute the power function regardless of job type
  • Before: task = TASK_MAPPING['power']
  • After: task = TASK_MAPPING[self.type]
  • Impact: Fibonacci jobs now correctly calculate fibonacci numbers instead of powers

⚙️ Configuration Updates

• Updated Dockerfile to use Python 3.13 base image
• Updated docker-compose.yml with latest infrastructure versions
• Updated okteto.yml:
  • Added build configuration for custom image
  • Updated deploy commands to use environment variable substitution
  • Added pytest test configuration
• Updated all Kubernetes manifests to use ${OKTETO_BUILD_APP_IMAGE}
• Created pytest.ini for pytest configuration

Testing in Okteto

✅ Deployed and validated in Okteto namespace

• All services running healthy
• Public endpoint accessible: https://web-agent-4dx94ofejmcy.demo.okteto.dev
• End-to-end functionality verified
