tracecov 0.20.0

Schema-level API coverage down to individual keywords.

TraceCov

Schema-level API coverage down to individual keywords.

Your API tests pass. But did you actually test the validation rules?

Hitting POST /users with {"name": "Alice", "age": 30} gives you 100% endpoint coverage—but you haven't tested empty names, negative ages, or strings that are too long.

TraceCov measures coverage at the schema keyword level: minLength, pattern, enum, minimum - not just endpoints.

Install

pip install tracecov

Quick Start

import tracecov
import requests

# Load your OpenAPI schema
coverage = tracecov.CoverageMap.from_path("openapi.json")

# Wrap your session to track requests
session = coverage.requests.track_session(requests.Session())

# Run your tests as usual
session.post("https://api.example.com/users", json={"name": "Alice"})
session.get("https://api.example.com/users/123")

# Generate the report
coverage.save_report()
