SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Property-based testing provides a structured approach to discovering edge cases by testing properties rather than specific cases, helping teams improve test coverage across languages and smart contracts.

Core Features & Use Cases

Pattern-focused guidance: identifies serialization, parsing, normalization, validators, and invariants to apply PBT where it adds value.
Cross-language applicability: strategies that work across multiple languages and smart-contract ecosystems.
Decision framework: includes a property catalog (Roundtrip, Idempotence, Invariant, etc.), a decision tree, and practical guidelines for test design.

Quick Start

Define a property describing the desired behavior, then run your test suite to automatically generate and validate diverse inputs.

FAQPage Schema

What is property-based testing and how does it find edge cases?▼

Property-based testing discovers edge cases by validating properties rather than specific instances. It automatically generates diverse inputs to test behaviors like serialization, parsing, and normalization, improving test coverage across languages and smart contracts.

How do I test serialization roundtrip and parsing invariants?▼

To test serialization roundtrip and parsing invariants, define a property describing the desired behavior, such as data surviving a serialize-deserialize cycle. Run your test suite to automatically generate and validate diverse inputs against this property.

Can I use property-based testing for smart contracts and validators?▼

Yes, property-based testing works across multiple languages and smart-contract ecosystems. It applies during test design and code reviews to formalize invariants, helping validate smart-contract validators and data structures effectively.

Does property-based testing work across different languages?▼

Property-based testing provides cross-language applicability, offering language-agnostic strategies and examples. It uses a decision framework with a property catalog including Roundtrip, Idempotence, and Invariant to guide implementation across different environments.

What is the best way to apply property-based testing during code reviews?▼

The best way to apply property-based testing during code reviews is using a decision tree to identify where invariants matter. Formalize properties like Idempotence and Invariant for normalization and validators to guide robust test design.

When should I not use property-based testing for my test suite?▼

You should avoid property-based testing when specific static inputs are sufficient, as it focuses on discovering edge cases through generated diverse inputs. If your task lacks clear invariants like Roundtrip or Idempotence, example-based tests may be more appropriate.
