Evaluate prompt effectiveness by measuring test coverage and mutation score improvements

Introduction

Prompt Library: Testing Prompts

Objective

Run the testing prompt library simulator with all 7 prompts (Test Generation, Edge Case Discovery, Adversarial Testing, Mutation Analysis, Property Derivation, Concurrency Testing, Regression Test). Observe each prompt's template, constraints, output format, and execution results (tests generated, edge cases found, bugs found, coverage/mutation improvements). Review the prompt effectiveness analysis and loop integration guide.

15+ reusable prompts for test generation, edge case discovery, adversarial testing, mutation analysis, property derivation, and concurrency testing.
