Standalone Pact Stub Server

This project provides a server that can generate responses based on pact files. It is a single executable binary. It implements the V3 Pact specification.

Online rust docs

The stub server works by taking all the interactions (requests and responses) from a number of pact files. For each interaction, it will compare any incoming request against those defined in the pact files. If there is a match (based on method, path and query parameters), it will return the response from the pact file.

Command line interface

The pact stub server is bundled as a single binary executable pact-stub-server. Running this with out any options displays the standard help.
