Tdd Implementation

Implements strict Test-Driven Development workflow:

TDD Cycle

1. Red Phase

• Write a failing test that clearly specifies desired behavior
• Test should be specific, readable, and focused on one piece of functionality
• Use descriptive test names that explain what is being tested
• Include edge cases and error conditions in test scenarios

2. Green Phase

• Write the minimal code required to make the test pass
• Focus on making the test work, not on perfect implementation
• Avoid adding functionality beyond what the test requires
• Use simple, straightforward solutions initially

3. Refactor Phase

• Improve code design while keeping tests green
• Apply design patterns and clean code principles
• Remove duplication and improve readability
• Ensure all tests still pass after refactoring

Verification Steps

After each TDD cycle:

1. Test Execution: Run uv run pytest to verify all tests pass
2. Quality Checks: Run uv run black . for formatting
3. Linting: Run uv run flake8 . for style compliance
4. Type Checking: Run uv run mypy . for type safety
5. Coverage: Periodically run uv run pytest --cov=ras_balancer

Chunking Strategy

• Work in small, manageable pieces of functionality
• Each chunk should implement one specific feature or behavior
• Verify each chunk completely before moving to the next
• Maintain a continuous green state throughout development

Integration with AGENTS.md

Follow project conventions for:

• Test structure and naming
• Assertion patterns (np.allclose, pytest.raises)
• Fixture usage and test organization
• Coverage requirements and quality gates This skill ensures systematic, test-first development that maintains high code quality throughout the implementation process.
