golang-testing
by affaan-mThe golang-testing skill helps you write and improve Go tests with table-driven cases, subtests, benchmarks, fuzzing, and coverage-aware TDD. It is designed for developers working on real Go code who want practical, idiomatic guidance rather than generic testing advice.
This skill scores 67/100, which is above the listing threshold and means it is worth installing for agents that need structured Go testing help. Directory users should see it as a practical, workflow-oriented guide for common testing tasks, but not a fully polished or strongly operationalized skill because it lacks supporting files and has some placeholder/test-like signals.
- Covers concrete Go testing workflows like table-driven tests, subtests, benchmarks, fuzzing, and test coverage, which gives agents useful task coverage.
- Includes explicit activation guidance and a step-by-step TDD cycle, improving triggerability and reducing guesswork for test-related tasks.
- The body is substantial with multiple headings and code examples, suggesting real instructional content rather than a stub.
- No install command, scripts, or reference files are present, so agents must rely mainly on the prose in SKILL.md.
- Placeholder and test-like signals appear in the repository, which lowers trust slightly and suggests the workflow may not be fully production-hardened.
Overview of golang-testing skill
The golang-testing skill helps you write and improve Go tests using idiomatic patterns: table-driven tests, subtests, benchmarks, fuzzing, and coverage-aware TDD. It is best for developers who already have Go code in hand and want a more reliable test design, not just a generic prompt that says “write tests.”
What this skill is for
Use the golang-testing skill when your goal is to add or reshape tests for real Go code: new functions, existing packages with weak coverage, performance-sensitive paths, or input-validation logic that benefits from fuzzing. The main job-to-be-done is turning a rough testing task into a concrete Go test strategy with readable test cases and predictable execution.
Why it is useful
The golang-testing skill is strongest when you want idiomatic Go output instead of framework-heavy advice. It emphasizes patterns Go teams actually use: arranging cases cleanly, naming subtests well, keeping test code maintainable, and deciding when TDD, benchmarks, or fuzz tests are worth the overhead.
Best fit and limits
This skill is a good fit for standard Go projects, library code, services with unit-test coverage, and teams following TDD or incremental test-first workflows. It is less useful if you need deep integration test orchestration, complex mocking frameworks, or language-agnostic QA planning. For those cases, a broader test strategy prompt may be a better starting point.
How to Use golang-testing skill
Install and activate it
For golang-testing install, add the skill to your Claude Code workflow with:
npx skills add affaan-m/everything-claude-code --skill golang-testing
Once installed, trigger it when you are about to write tests, not after the code is already finalized. The best results come when the skill sees the target function, package, or failure mode early.
Give it a test-shaped prompt
For practical golang-testing usage, do not ask only for “unit tests.” Provide the behavior, inputs, edge cases, and constraints you care about. A strong prompt looks like this:
- “Write table-driven tests for
ParseDurationcovering valid inputs, invalid strings, whitespace, and boundary values.” - “Create a TDD plan for
NormalizeEmailwith subtests for empty, mixed-case, unicode, and malformed addresses.” - “Add a benchmark for this parsing function and explain what to measure.”
The more specific the expected behavior, the less the skill has to guess.
Read these files first
For golang-testing guide work, start with SKILL.md to understand the workflow and examples, then inspect any repository-specific files the skill references, such as README.md, AGENTS.md, metadata.json, or supporting folders like rules/, resources/, and references/ if they exist. In this repository, the skill content is concentrated in SKILL.md, so that file is the first stop.
Use it in a TDD workflow
The skill is most effective when you use it as a test-design assistant around the RED-GREEN-REFACTOR cycle. First ask for a failing test that proves the requirement. Then ask for the smallest code change that passes. After that, request a refactor pass focused on readability, duplicated setup, and stronger case coverage. This sequence is especially useful for golang-testing for Test Automation because it keeps test intent explicit and reduces overfitting to implementation details.
golang-testing skill FAQ
Is golang-testing only for unit tests?
No. The golang-testing skill covers unit-style tests, table-driven patterns, subtests, benchmarks, fuzz tests, and coverage-focused TDD. It is still primarily about Go code behavior, so it is not a replacement for full system-test orchestration.
Do I need to already know Go testing well?
Basic Go familiarity helps, but the skill is still useful if you can describe the function or package you want tested. It can guide structure and workflow, but it works best when you can provide inputs, expected outputs, and edge cases.
How is this different from a normal prompt?
A normal prompt often produces generic test examples. The golang-testing skill is more decision-oriented: it pushes toward idiomatic Go patterns, clearer case structure, and a test-first workflow that fits how Go projects are maintained.
When should I not use it?
Skip this skill if your task is mostly browser automation, end-to-end UI testing, or non-Go test infrastructure. It is also a weaker fit if you have no implementation details yet and only need abstract testing theory.
How to Improve golang-testing skill
Provide the behavior, not just the topic
The biggest quality jump comes from giving the skill exact behavior to validate. Instead of “test this parser,” include accepted formats, invalid inputs, error expectations, and any ordering or performance requirements. That lets the golang-testing skill produce tighter cases and fewer placeholder assertions.
State the test style you want
If you want table-driven tests, subtests, fuzzing, or benchmarks, say so explicitly. The golang-testing skill can choose well, but your output improves when you declare the priority: readability, edge-case coverage, performance regression detection, or TDD steps.
Watch for common failure modes
The main risks are over-mocking, weak edge coverage, and tests that mirror implementation details instead of contract behavior. If the first result feels too shallow, ask for more boundary cases, clearer test names, or a refactor toward table-driven structure. For golang-testing skill adoption, that feedback loop matters more than asking for a bigger example.
Iterate with repository-specific constraints
After the first pass, add the constraints that actually affect your codebase: package layout, error style, use of t.Helper(), parallel test rules, or CI limits. If you are using golang-testing for Test Automation in a larger Go repo, also specify what should remain stable across refactors so the skill can avoid brittle tests and focus on durable assertions.
