## AI interpretation — verify before relying

respx mocks the httpx HTTP client library for testing, letting you define request patterns and stub responses without hitting real servers.

Verdict: respx is a stable, well-maintained mocking utility for httpx with no known vulnerabilities, permissive licensing, and low install friction. It is suitable for test suites that need to stub HTTP interactions without external dependencies.
