What problem does it solve?

This Skill provides comprehensive guidance and examples for writing robust, maintainable, and efficient tests in Go, ensuring code quality and reliability.

Core Features & Use Cases

  • TDD Workflow: Learn and apply the Red-Green-Refactor cycle for Go development.
  • Advanced Testing Techniques: Implement table-driven tests, subtests, benchmarks, fuzzing, and golden file testing.
  • Test Helpers & Mocking: Utilize helper functions, temporary files, and interface-based mocking for cleaner tests.
  • Use Case: When developing a new Go service, use this Skill to ensure all functions are thoroughly tested using idiomatic Go practices, including performance benchmarks and security fuzz tests.

Quick Start

Use the golang-testing skill to write a table-driven test for a new Go function.

Frequently Asked Questions about golang-testing

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

FAQPage Schema
How do I write a table-driven test in Go?▼

Go fuzzing tests supply random data to find edge cases and security vulnerabilities. Implement fuzz targets to continuously generate unexpected inputs, ensuring your functions handle malformed data reliably without crashing.

How do I measure and improve test coverage in Go?▼

Go benchmarks measure function execution time and memory allocations using the testing package. Run benchmark tests to analyze performance metrics, identify bottlenecks, and optimize code efficiency through comparative profiling.

What is the Red-Green-Refactor cycle for Go TDD?▼

The Red-Green-Refactor cycle is a TDD methodology where you write a failing test, implement code to pass it, then refactor. Following this workflow ensures reliable, maintainable Go development with comprehensive test coverage.

How do I use interface-based mocking for Go tests?▼

Interface-based mocking in Go defines an interface for dependencies, allowing you to substitute mock implementations during tests. Utilize test helpers and temporary files to isolate components and verify function interactions cleanly.

Does Go support golden file testing for complex outputs?▼

Golden file testing compares function output against saved expected files to validate complex results. Implement this technique using temporary files and test helpers to maintain reliable regression tests for large data structures.
