It listens on configurable ports for HTTP traces (8126), OTLP HTTP (4318), and OTLP gRPC (4317), and provides a web UI for inspecting received traces and managing test sessions.\n\nThe agent performs trace invariant checks (trace count headers, tracer version headers, content length validation), stores all submitted data for retrieval via API, and supports snapshot testing for characterization-based regression detection. It can proxy requests to a real Datadog agent or forward LLM observability events directly to Datadog. It also records and replays third-party API calls (OpenAI, Azure OpenAI, DeepSeek) for reproducible testing.","worth_installing":"Yes. The package is actively maintained, has no known vulnerabilities, and is purpose-built for testing Datadog APM integrations. Install it if you develop or maintain a Datadog APM client library or need to validate trace behavior in CI/CD. The low install friction and permissive license make it a straightforward addition to test infrastructure."},"id":"ddapm-test-agent","links":{"html":"https://skillfed.io/packages/ddapm-test-agent","md":"https://skillfed.io/packages/ddapm-test-agent.md","pypi":"https://pypi.org/project/ddapm-test-agent/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-14","license_spdx":null,"license_treatment":"permissive","name":"ddapm-test-agent","python_support":"supports_current","summary":"Test agent for Datadog APM client libraries"},"popularity":{"monthly_downloads":3346621,"position":2653,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.65.0"}
