Apply James Shore's "Testing Without Mocks" pattern language to write tests that are narrow, sociable, state-based, and free of mocks/spies. Use this skill when writing or refactoring tests for any codebase, when the user asks to test code without mocks, when applying Nullable infrastructure patterns, when structuring code with A-Frame Architecture for testability, or when converting legacy mock-heavy tests.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'testing-without-mocks' ] || [ -L ~/.agents/skills/'testing-without-mocks' ]; then echo 'A skill folder named testing-without-mocks already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hugoduncan/psi' "$d" && git -C "$d" checkout --quiet '61d2c6e7761892994e1b4ded2a2b8e413bc76684' -- '.psi/skills/testing-without-mocks' && mkdir -p ~/.agents/skills && cp -R "$d"/'.psi/skills/testing-without-mocks' ~/.agents/skills/'testing-without-mocks' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'testing-without-mocks' ~/.claude/skills/'testing-without-mocks' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
