Overview

This specialized GitHub Copilot chat mode enables comprehensive, CoreStory-powered test generation directly within your IDE. Unlike the base .github/copilot-instructions.md file (which provides general guidance for all Copilot interactions), this chat mode creates a focused test generation persona that you can invoke on-demand for systematic, high-quality test suite creation.

What's a Chat Mode?

Chat modes are specialized AI personas in GitHub Copilot that you can switch between for different tasks. Think of them as "expert modes" - when you need comprehensive test generation with architectural analysis, you invoke the Test Generator mode. When you need general coding help, you use the default mode.

Why Use This Chat Mode?

The Test Generator chat mode provides:

• ✅ Systematic test generation using the T.E.S.T. framework (Target → Evaluate → Specify → Test)
• ✅ CoreStory architectural analysis before writing any tests
• ✅ Progressive refinement through validated rounds (not 100 tests at once)
• ✅ 10 ready-to-use prompt templates for common scenarios
• ✅ Quality validation checklists built into the workflow
• ✅ Advanced testing patterns (test data builders, property-based testing, contract testing, etc.)
• ✅ Comprehensive edge case coverage with systematic discovery

This complements your base .github/copilot-instructions.md by providing:

• Deeper, more prescriptive guidance for test generation specifically
• Ready-to-use templates you can invoke immediately
• Systematic workflows that ensure quality
• Advanced patterns not covered in general instructions
