SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers write more robust and comprehensive tests by leveraging Property-Based Testing (PBT), which focuses on testing general properties of code rather than specific examples, leading to the discovery of edge cases that traditional testing might miss.

Core Features & Use Cases

  • Test Generation: Automatically generate property-based tests for various code patterns like serialization, validation, and pure functions.
  • Test Review: Analyze existing PBT tests to identify issues like tautological properties or weak assertions.
  • Design Assistance: Guide the design of features using Property-Driven Development (PDD) to define specifications before implementation.
  • Refactoring for Testability: Suggest code modifications to make it more amenable to property-based testing.
  • Use Case: When developing a new serialization library, use this Skill to generate roundtrip tests that ensure data encoded and then decoded remains unchanged, catching subtle bugs in edge cases.

Quick Start

Use the property-based testing skill to generate property-based tests for the provided Python code snippet.

Frequently Asked Questions about property-based-testing

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

FAQPage Schema
How do I generate property-based tests to find edge cases in my code?▼

Generate property-based tests by defining general properties and strategies rather than specific examples, allowing the framework to automatically discover edge cases. This Skill provides tooling to detect opportunities and generate appropriate tests for patterns like pure functions and serialization.

What is property-based testing and when should I use it?▼

Property-based testing checks general properties of code rather than specific examples to catch subtle bugs. Use it when developing features like serialization libraries or validation logic where traditional testing might miss edge cases.

Can I use property-based testing frameworks like hypothesis and fast-check with this tool?▼

Yes, property-based testing with this Skill supports frameworks like hypothesis and fast-check. It provides comprehensive guidance and tooling across multiple programming languages to facilitate test generation and strategy definition.

How do I review existing property-based tests for weak assertions or tautologies?▼

Review existing property-based tests by analyzing them for issues like tautological properties or weak assertions. This Skill evaluates your current tests to identify quality issues and suggests improvements for more robust coverage.

What is the best way to design features using Property-Driven Development?▼

Design features using Property-Driven Development by defining specifications and properties before implementation. This Skill guides the process and suggests code refactoring modifications to make your code more amenable to property-based testing.

Does property-based testing work for smart contract development?▼

Yes, property-based testing supports smart contract development alongside multiple programming languages. It facilitates generating tests with appropriate strategies and edge cases tailored to the specific requirements of smart contracts.
