Open Telemetry

The pact cli supports native opentelemetry for traces and application logs.

It is opt-in via --enable-otel, you must set

- `--enable-otel-traces` for traces
- `--enable-otel-logs` for logs
- `--log-level` must be set
- `--enable-otlp-exporter` must be set

By default, --otel-exporter-endpoint will route to http://localhost:4318.

Currently instrumented crates are

  • pact-broker-cli
  • pact-cli

Ecosystem

The ecosystem is built up of multiple different crates, each which serve a different purpose.

All active crates are listed below.

Core

pact_models This is a library that provides the Pact models and functions for reading and writing pact files.

pact_matching This is a library that provides the Pact functions for matching requests and responses.

pact_mock_server This is a library that implements the in-process mock server for matching HTTP requests and generating responses from a pact file. It implements the V3 Pact specification and V4 Pact specification

Library Consumers

pact_consumer This is a library that provides the Pact consumer test support and DSL for use in Rust projects.

pact_verifier This library provides support for verifying a provider against pact files.

External Consumers

FFI

pact_ffi This is a library that implements exported functions using C bindings for use in foreign languages.

CLI

pact_mock_server_cli A command line application that provides both a restful web api and command line interface to run pact mock servers and is able to manage multiple mock servers. The lifecycle of each mock server can be controlled by the restful web api or through the command line interface. It implements the V4 Pact specification.

pact_verifier_cli Command line executable that uses the pact_verifier to be able to verify a running provider against pact files.

Plugins

pact-plugin-driver A support library that provides an interface for interacting with Pact plugins

pact-plugin-cli Command line executable to manage and install Pact plugins.

Satellite

pact-stub-server Command line executable that provides a server that can generate responses based on pact files. It implements the V4 Pact specification.
