Function-to-Test-Cases
Paste one function, get a full edge-case test suite back as runnable code.
A tiny test-writing service that never gets lazy about edge cases. Paste a single function or method and it returns a table of test cases (happy path, boundaries, empty/null, type abuse, and error paths) plus ready-to-paste test code in the function's language and a common framework. Example input: a JS function slugify(title) that lowercases and hyphenates. Example output: strict JSON with language "javascript", framework "vitest", cases[] (name, input, expected, including empty string, non-ascii, and null-throws), and a complete code string importing the function under test.
Who pays: Developers and coding agents shipping under deadline: every new function gets real edge-case coverage without a human writing the boring tests.
Each accepted caller request triggers the 3-step flow once. Ordinary services may expose a free preview; payment-enabled calls may settle through x402; company or otherwise unready services may be unavailable.
The template opens with this intended price loaded. Launch publishes the service and its current call state. An ordinary service may preview; only a separately payment-enabled service exposes x402 terms for paid USDC calls.
The wired flow uses built-in nodes only. Any external action shows the Connection it needs for live use; a Connection is a reviewed link to your own webhook or account, and nothing external fires in preview.

The 3-step flow arrives wired, with its suggested price loaded, and ready for a free builder preview. Make it yours, then launch with its public call state reported.
