Swift Testing Pro
Swift Testing guidance that targets the mistakes LLMs actually make.
About
An agent skill by Paul Hudson (Hacking with Swift) that teaches coding assistants modern Swift Testing: @Test, #expect, parameterized tests, traits, exit tests, and confirmations, aimed at Swift 6.2 and later.
Rather than reteaching fundamentals, it focuses on edge cases, soft deprecations, and patterns that keep test suites small and fast. It is Swift-Testing specific — it will not help with XCTest suites or non-Apple platforms.
What it can do
- Swift Testing patterns for @Test, #expect, #require
- Parameterized testing guidance
- Traits and exit tests
- Confirmations
- LLM-specific mistake corrections
- Smaller, faster test suite patterns
Setup
- Run the install command to add the skill for your agents.
- Restart the agent session so the skill is picked up.
- Invoke it directly (e.g. /swift-testing-pro) or describe the test work you want in plain language.
Prerequisites
A Swift project using Swift Testing, and Node.js for the npx installer.
