Test Driven Development

When to use

• User asks to write tests, add test coverage, or create a failing test first
• User asks to implement a feature using TDD or test-first development
• User mentions "red-green-refactor", "acceptance test", or "unit test"
• User asks to verify that tests pass before committing
• User asks about test strategy or test structure

Overview

This project follows Test Driven Development with acceptance tests and unit tests.

Rules

1. Preserve file encoding
2. Analyze test setup (which test framework is actually used ?, how to build (see relevant skill) ?, how to run test (see relevant skill) ?, how to analyze code coverage (see relevant skill) ?)
3. Create a failing acceptance test if it does not exist. Add unit tests to test small cases or technical parts.
4. Implement the feature. Always double check before implementing if the function does not exist.
5. Run tests and get feedback
6. Refactor

Run tests and get feedback

CRITICAL: Before modifying the code:

Before committing, always run ALL tests in the solution file. If the repo contains multiple .sln files, confirm which sln to use before.

1. Tests pass with assertions - Verify tests have meaningful assertions that check expected behavior
2. Code coverage verified - Check coverage report for new/modified code
