feat: Testing & Quality Assurance (Sprint 7)

[fregataa]

Overview

Achieve comprehensive test coverage (>70%) and establish automated testing infrastructure for the config-server.

Goals

• Establish automated testing infrastructure
• Achieve >70% code coverage
• Set up CI/CD pipeline for automated testing
• Ensure code quality through linting

Tasks

1. Testing Infrastructure

• Set up testcontainers for PostgreSQL
• Configure test database with migrations
• Set up code coverage reporting
• Configure golangci-lint
• Set up GitHub Actions for automated testing

2. Unit Tests

• Domain models unit tests
• Service layer unit tests
• Error handling unit tests
• Validation logic tests
• Business logic tests

3. Integration Tests

• Repository layer integration tests (with real DB)
• API integration tests (end-to-end)
• Bootstrap token flow tests
• Service Discovery tests
• Health check tests

4. Code Quality

• Run golangci-lint and fix issues
• Fix code smells and duplications
• Optimize slow tests
• Document test utilities

Deliverables

• >70% code coverage
• Automated test suite in CI
• Integration test suite with testcontainers
• Clean code passing all linters
• Test documentation

Success Criteria

• All tests passing in CI
• Coverage report accessible
• Fast test execution (<5 min total)
• Zero critical linting issues

Notes

• Focus on service and repository layers first
• Use table-driven tests for domain logic
• Mock external dependencies where appropriate
