testing

testing is a skill for Claude Code, Codex from robium-ai/robium. It costs 131 tokens per session (3,751 once invoked), scanned A, a copy of testing, MIT.

A robotics testing guide for checking robot nodes, startup files, simulated behavior, and learned policies. It treats a smoke test—a quick check that the main system starts and works—as a required part of finishing a robotics project.

In plain words
What is it for?
Planning unit tests, startup checks, simulation-based regression tests, and policy evaluations for robotics applications. It also helps set up testing in a robotics code repository's continuous-integration checks.
Why use it?
Robotics software can fail in ways that ordinary tests miss, such as a node not receiving messages or a launch file missing an important component. It helps catch these failures before the project is considered complete.

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 5d 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.

Origin

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 ros2 skill's launch-testing-launched-process usage pattern for the four-part scaffold (generate_test_description, ReadyToTest, an active TestCase, @post_shutdown_test), and the upstream launch_testing README and ROS 2 testing docs (linked in References) for full API depth. 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).

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 robium-ai/robium (9 stars, last pushed 7d ago), licensed MIT. It adds 131 tokens to every session and 3,751 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to testing, differing in 21 lines, and is treated as a copy.
