SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you reliably fix bugs by ensuring that each fix is accompanied by a test that reproduces the bug, preventing regressions and increasing confidence in code stability.

Core Features & Use Cases

  • Reproduce Bugs: Write failing tests that specifically target and demonstrate a bug.
  • Targeted Fixes: Apply minimal code changes to make the failing test pass.
  • Regression Prevention: The new test acts as a safeguard against the bug reappearing.
  • Use Case: When a user reports that a discount calculation is sometimes incorrect, use this skill to write a test that fails with the incorrect input, then fix the calculation logic to make the test pass.

Quick Start

Use the tdd-bug-fix skill to fix the bug in the PriceCalculator class that causes incorrect discount calculations.

FAQPage Schema
How do I fix bugs using TDD in Swift?▼

Fix bugs using TDD in Swift by writing a failing test that reproduces the bug, applying minimal code changes to pass the test, and optionally refactoring while maintaining test coverage. This prevents regressions and increases confidence in code stability.

What is the TDD workflow for bug fixing?▼

The TDD workflow for bug fixing involves reproducing bugs with failing tests (RED), applying minimal fixes to pass those tests (GREEN), and optionally refactoring code while maintaining test coverage to prevent future regressions.

Can I use test-driven development to prevent regression bugs in Swift applications?▼

Yes, you can use test-driven development to prevent regression bugs in Swift applications by writing failing tests that reproduce the original bug, then fixing the code to pass the test, which acts as a safeguard against the bug reappearing.

Why should I write a failing test before fixing a bug?▼

You should write a failing test before fixing a bug to verify that the bug is accurately reproduced, ensuring that your subsequent minimal code fix specifically targets the issue and that the test remains as a permanent safeguard against regressions.

When should I not use TDD for bug fixing?▼

You should avoid TDD for bug fixing when the bug cannot be reliably reproduced through an automated test, or when the codebase lacks existing test infrastructure to support regression testing workflows in Swift applications.
