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.
Example use cases
Scaffold tests for a new utility function
“I just wrote this JavaScript utility function and my project uses Jest — can you generate unit tests for it that match the Jest framework? Here's the function: `function clamp(value, min, max) { return Math.min(Math.max(value, min), max); }`”
Auto-generate tests before code review
“Before I submit this PR, can you write pytest unit tests for this Python class I built? I want tests covering the main methods and edge cases, matching our pytest setup: `class Cart: def __init__(self): self.items = [] def add(self, item): self.items.append(item)`”
Bootstrap test coverage for legacy code
“This Go function has zero test coverage and we use the standard `testing` package — can you generate tests for it that match that framework? Here's the function: `func Divide(a, b float64) (float64, error) { if b == 0 { return 0, errors.New("division by zero") } return a / b, nil }`”
Technical details
Endpoint
POSThttps://dev-5090-box.tailfb4c1f.ts.net/v1/coder/test-gen?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
