Property-Based Testing Design

What problem does it solve?

This Skill guides you through the process of designing and implementing property-based tests, ensuring your code behaves correctly under a wide range of inputs and conditions.

Core Features & Use Cases

• Identify Invariants: Define what must always be true about your code's behavior.
• Design Generators: Create strategies to produce diverse and interesting test data.
• Implement Tests: Write executable property tests in Go (rapid), Python (Hypothesis), or TypeScript (fast-check).
• Use Case: You're building a financial calculation module. Use this Skill to design property tests that ensure the balance never goes below zero, regardless of the transaction amounts and sequences.

Quick Start

Use the property-based testing skill to design generators for testing a Go function that processes user input strings.
