Standalone Pact Mock Server

This project provides both a restful web api and command line interface to run pact mock servers. It is a single executable binary 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.

Online rust docs

Command line interface

The mock server is bundles as a single binary executable pact_mock_server_cli. Running this with out any options displays the standard help.

The following options are available for all subcommands:

Host: -h, --host

This sets the host the master mock server runs on. By default this will be localhost.

Sub-commands

help

This prints either the main help or the help for a sub-command.

start

Usage: pact_mock_server_cli start [OPTIONS]

Options:
      --help                     Print help and exit

Restful JSON API

The master mock server provides a restful JSON API, and this API is what the command line sub-commands use to communicate and control the master server.

This is returned when if the mock server was created successfully.

422 Unprocessable Entity

This is returned if the pact JSON could not be parsed or the mock server could not be started.

GET /mockserver/:id

Returns details of the mock server with :id, which can be either a mockserver ID or port number.

example request:
