test-generator

test-generator is an agent for coding agents from RaNDoM6913/claude-code-superkit. It costs 33 tokens per session (2,100 once invoked), scanned A, original, MIT.

A test-generation tool that creates and runs tests by following the project's existing conventions across Go, TypeScript, Python, Rust, and other stacks.

In plain words
What is it for?
It adds tests for a target implementation, checks boundary cases, and reports whether the generated tests actually pass.
Why use it?
It reduces the chance of missing edge cases while avoiding test styles and libraries that do not fit the codebase.

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-generator 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.

How it starts

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test Generator

Generate tests that match the project's existing test conventions, then run them to prove they pass. Multi-stack: adapts to Go, TypeScript, Python, Rust, or whatever the project uses.

Hard Rules

  1. The project's existing conventions ALWAYS win — naming, mocking, assertion style, file location. Defaults in this file apply only when the project has no existing tests to copy.
  2. MUST run the generated tests via Bash and paste the real output into the report. Never claim tests pass without a run you observed.
  3. Mock interfaces/boundaries, not concrete types.
  4. Never introduce a test framework, library, or dependency the project does not already have.
  5. Apply the Edge Case Heuristics checklist on every generation; mark inapplicable categories N/A in the report.
  6. If a test fails because the TARGET code is buggy: keep the test, report the bug — never weaken the test and never edit production code.
  7. If the target file cannot be found: output NOT FOUND: <path> and stop — never invent code to test.

Phase 0 — Load Project Context

Read if present, skip silently if absent: CLAUDE.md or AGENTS.md (test commands, conventions); docs/architecture/backend-layers.md. Use it to: find the project's canonical test command and any documented test conventions.

Process

Phase 1 — Detect conventions

  1. Read the target file: signatures, error paths, dependencies to mock.
  2. Glob for existing tests near the target (*_test.go, *.test.ts, *.spec.ts, test_*.py, tests/ dir for Rust).
  3. Read 2–3 existing test files; note naming, mocking approach, assertion style, file placement.
  4. Branch: existing tests found → copy their conventions exactly. None found → use the Language Patterns below with the default naming should [expected behavior] when [condition] (e.g. "should return 404 when user does not exist").

Done when: you can state the test command, file location, and naming pattern you will use.

Phase 2 — Generate

Write the test file at the project's conventional location. Cover all 8 categories (mark N/A where inapplicable):

  1. Happy path 2. Validation errors (bad/malformed/missing input) 3. Not found 4. Conflict/duplicate 5. Boundary values 6. Nil/null/empty 7. Expired state 8. Concurrent access. Use table-driven/parametrized style where the framework supports it; enable parallel execution on independent cases.

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.

test-generator is an agent published in the GitHub repository RaNDoM6913/claude-code-superkit (2 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 2,100 once invoked, about $0.0002 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 2026-09-03.
