testing

testing is a skill for Claude Code, Codex from connorads/dotfiles. It costs 118 tokens per session (4,967 once invoked), scanned A, original, no licence file.

A guide for designing and writing tests that check how software behaves. TDD, or test-driven development, means writing a test before the code that makes it pass.

In plain words
What is it for?
It is for testing behavioural changes, selecting unit or end-to-end tests, using fakes, reducing flaky tests, and creating tests that make refactoring safer.
Why use it?
It helps choose suitable test types, avoid fragile tests, and preserve expected behaviour during bug fixes and refactoring.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

testing is a skill published in the GitHub repository connorads/dotfiles (18 stars, last pushed today), with no licence file. It adds 118 tokens to every session and 4,967 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
