SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Fuzz testing in Go helps you discover edge cases, panics, and correctness issues by automatically generating inputs and exercising your code paths.

Core Features & Use Cases

  • Coverage-guided fuzzing using Go's native fuzzing engine to explore untested code paths.
  • Corpus-driven fuzzing with seed inputs to guide mutation toward interesting cases.
  • Property-based testing patterns and crash-detection workflows for Go packages.
  • Easy integration with existing unit tests by adding Fuzz functions in _test.go files.

Quick Start

Add fuzz tests in Go by creating Fuzz functions in _test.go files and run the Go fuzzing workflow to start automated input generation.

FAQPage Schema
How do I automate Go fuzz testing for my packages?

Automate Go fuzz testing by adding Fuzz functions to _test.go files and running the native Go fuzzing engine to automatically generate inputs and exercise code paths in pkg/ and internal/ directories.

What is coverage-guided fuzzing in Go and how does it find edge cases?

Coverage-guided fuzzing in Go uses the native fuzzing engine to explore untested code paths by automatically generating and mutating inputs, helping you discover edge cases, panics, and correctness issues.

How do I use a seed corpus for corpus-driven fuzzing in Go?

Corpus-driven fuzzing in Go uses seed inputs to guide mutation toward interesting test cases, satisfying requirements for seed corpus usage and property-based testing patterns for functions with parameters.

Can I integrate fuzz tests with my existing Go unit tests?

Integrate fuzz tests with existing Go unit tests by adding Fuzz functions in _test.go files alongside your current tests, using test function naming with Fuzz prefixes and safe error handling workflows.

What are the naming requirements for Go fuzz test functions?

Go fuzz test functions require Fuzz prefixes in their naming convention within _test.go files, ensuring safe error handling and proper integration with the native fuzzing engine for automated input generation.

When should I use property-based testing patterns for Go packages?

Use property-based testing patterns for Go packages when you need crash-detection workflows and automated input generation to discover correctness issues in unit-level code located in pkg/ and internal/ directories.
