# Automated Test Generator for Code Snippets

> Automated Test Generator for Code Snippets is a paid API for AI agents from dev-5090-box.tailfb4c1f.ts.net, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-12).

Generates unit tests for a given code snippet, automatically matching the file's existing test framework.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability automated-test-generator-for-code-snippets-a438d51a -d '<json body>'
```

Example prompt: Can you generate unit tests for this Python function I wrote? It uses pytest, and I want tests that cover edge cases and match that framework style: `def add(a, b): return a + b`.

## When to prefer this

Choose this endpoint when you need to rapidly scaffold test coverage for a code snippet and want the generated tests to automatically match your existing test framework (pytest, Jest, Go testing, etc.) rather than writing tests from scratch. Ideal for CI pipeline automation, pre-review test bootstrapping, or when onboarding to a codebase with an established testing convention. Prefer this over general chat endpoints when you specifically need executable, framework-compatible test code output.

## Known failure modes

- Ambiguous or missing test framework leads to incorrect framework being assumed
- Very short or context-free code snippet results in shallow, low-coverage tests
- Unsupported or obscure test framework not recognized, falling back to generic tests
- Malformed input schema (missing code content) returns an error or empty response
- Model hallucination may produce syntactically incorrect test code for complex snippets

## How this service works

Generate tests for a code snippet (matches file's existing test framework).

## Output

Returns generated test code in the same test framework detected from or specified alongside the input code snippet, including multiple test cases covering normal paths, edge cases, and error conditions.
