SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Writing tests can be a tedious, time-consuming task that often gets skipped, leading to bugs and technical debt. This friction is particularly challenging for developers with ADHD. This Skill makes testing effortless.

Core Features & Use Cases

  • Automatic Test Generation: Analyzes your code and generates unit, integration, and E2E tests.
  • Learns Your Style: Recalls your preferred testing frameworks, assertion styles, and coverage requirements from memory.
  • Regression Test Creation: Automatically generates regression tests after bug fixes to prevent recurrence.
  • Use Case: You've just written a new function. Instead of manually crafting tests, you say "write tests for this function." The testing-builder analyzes your code, applies your preferred testing framework (e.g., Vitest), and generates a full suite of tests covering happy paths, edge cases, and invalid inputs.

Quick Start

After writing or modifying code, simply say:

write tests for this function

Or to create a regression test after a bug fix:

create regression test for this bug

Frequently Asked Questions about testing-builder

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automatically generate unit tests for my JavaScript functions?▼

Unit test generation analyzes your code structure and creates test cases covering happy paths, edge cases, and invalid inputs. This Skill generates ready-to-run unit tests in your preferred framework (Vitest, Jest, etc.) by analyzing function signatures and recall your testing patterns from memory.

Can I generate integration and E2E tests automatically, or just unit tests?▼

This Skill generates comprehensive test suites including unit, integration, and E2E tests from your code. It determines which test types are needed, applies your framework preferences, and outputs all three in aligned templates ready to run.

How do I create regression tests after fixing a bug?▼

After a bug fix, say 'create regression test for this bug.' The Skill analyzes the fix, recalls your testing patterns, and generates regression tests aligned with your framework and naming conventions to prevent the issue from recurring.

Does test generation work with TypeScript codebases?▼

Yes, test generation applies to both JavaScript and TypeScript codebases. The Skill analyzes your code, identifies test targets, and generates unit, integration, and E2E tests using your preferred framework and assertion style.

What frameworks does automatic test generation support?▼

Test generation works with various JavaScript/TypeScript frameworks. It learns and recalls your preferred testing framework, assertion styles, and coverage requirements from memory to generate aligned test templates.

Why should I use test generation instead of writing tests manually?▼

Test generation eliminates tedious, time-consuming manual test writing that often gets skipped, reducing technical debt and bugs. It's especially valuable for developers with ADHD by removing friction and automating comprehensive coverage.
