testing

testing is a skill for Claude Code from robium-ai/robium. It costs 131 tokens per session (3,649 once invoked), scanned A, original, MIT.

A testing guide for robotics software, covering checks at several levels: launch-file smoke tests, simulation-based regression tests, node unit tests, and policy evaluation. TDD, or test-driven development, means planning and writing tests as part of building the software.

In plain words
What is it for?
Use it when testing a robot application or node, adding smoke tests, setting up simulation regression tests, or planning tests for a new robotics project.
Why use it?
Robotics failures can happen even when individual code checks pass, such as when a node receives no messages or a launch file misses a required component.

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 6d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.

testing

The cross-cutting testing umbrella for robium. Robotics apps fail in layers a generic test suite misses — a node that never receives a message, a launch file that starts everything except the one node that mattered, a policy that looks fine on paper but never reaches the goal in sim. This skill frames the robotics-specific test pyramid and states the non-negotiable bar: a robium build is not done until its smoke test passes. It does not re-teach launch_testing/pytest mechanics for ROS 2 (that's ros2) or the lerobot-eval CLI (that's lerobot) — it frames both as test-pyramid layers and routes to them.

When to use this skill

  • Setting up tests for any new robium project — this should be planned into the build from the start, not bolted on after the fact.
  • The trigger phrases in the description: 'test the robot app', 'how do I test this node', 'smoke test', 'regression test in sim'.
  • Before claiming any robotics app or sample works — a claim of "done" without a passing smoke test is not verified, it's a guess.
  • Load alongside whatever skill is building the thing under test — ros2/ nav2/gazebo for the navigation vertical, lerobot for the manipulation vertical — this skill supplies the test framing, not a replacement for either.
  • Cross-references — go to the sibling skill instead when the question is:
    • ROS 2 launch_testing/pytest mechanics themselves (fixtures, process actions, assertions) → the upstream launch_testing README and ROS 2 testing docs (linked in References). The ros2 skill does not yet carry launch_testing content — until it does, go upstream directly rather than hunting for it there. This skill frames launch/node testing as a pyramid layer either way.
    • The lerobot-eval CLI and its flags → lerobot. This skill frames policy eval as a test-pyramid layer with a pass/fail bar; lerobot owns the eval mechanics.
    • Setting up the simulator a regression test runs against → gazebo or isaac-sim (or simulation if the choice isn't made yet).
    • Where the test data comes from — worlds, robot models, sample datasets, fixture folders, goldens → test-assets. This skill decides what to test and when it passes; test-assets supplies what it runs against.
    • General (non-robotics) testing practices — unrelated to this skill; use whatever generic testing guidance already applies to the language/ framework in question.
    • The whole-stack decision this feeds into → architect (plans testing into the brief, doesn't bolt it on later).

testing is a skill published in the GitHub repository robium-ai/robium (9 stars, last pushed 8d ago), licensed MIT. It adds 131 tokens to every session and 3,649 once invoked, about $0.0007 per session on Opus 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.
