test-runner

test-runner is a skill for Claude Code, Codex from RaNDoM6913/claude-code-superkit. It costs 24 tokens per session (893 once invoked), scanned A, original, MIT.

A test-running tool that detects a project’s language and test framework, then runs the appropriate automated tests.

In plain words
What is it for?
Use it to run backend, frontend, end-to-end, or all tests, with optional coverage when the project supports it.
Why use it?
It removes the guesswork of finding the right test command for projects using Go, TypeScript, Python, Rust, Java, or other supported setups.

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

test-runner 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 yesterday.

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.

Run Tests

Auto-detect the project's test runner and execute tests.

Target

Parse the user's request to determine scope and parameters. Accepted formats: backend, frontend, e2e, all, --coverage.

Step 1 — Detect Test Runner

Scan the project root and subdirectories for stack markers:

Marker Test Command Stack
go.mod go test ./... -count=1 Go
package.json + vitest config npx vitest run Vitest
package.json + jest config npx jest Jest
package.json + playwright config npx playwright test Playwright (e2e)
pyproject.toml / pytest.ini / conftest.py pytest Python (pytest)
pyproject.toml with [tool.unittest] python -m unittest discover Python (unittest)
Cargo.toml cargo test Rust
pom.xml mvn test Java (Maven)
build.gradle ./gradlew test Java/Kotlin (Gradle)
Makefile with test target make test Makefile

If a Makefile with a test target exists and the stack has one, prefer make test as it may include additional setup.

Step 2 — Determine Scope

Based on the user's request:

backend (or empty — default)

Run backend tests only:

  • Go: go test ./... -count=1 -short
  • Python: pytest tests/ or pytest
  • Rust: cargo test
  • Java: mvn test / ./gradlew test

If the project is a monorepo, cd into the backend directory first (detect by backend/, server/, api/, or src/ containing the go.mod/pyproject.toml).

frontend

Run frontend tests:

  • Vitest: npx vitest run
  • Jest: npx jest

If the project is a monorepo, cd into the frontend directory first (detect by frontend/, web/, client/, or app/ containing package.json).

e2e

Run end-to-end tests:

  • Playwright: npx playwright test
  • Cypress: npx cypress run
  • pytest + selenium: pytest tests/e2e/

all

Run all detected test suites sequentially. Report results for each.

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.
