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 V3 Pact specification .

# The mock server is bundles as a single binary executable pact_mock_server_cli. Running this with out any options displays
the standard help.
Copy ./pact_mock_server_cli v0.0.1
Standalone Pact mock server
USAGE:
pact_mock_server_cli [FLAGS] [OPTIONS] <SUBCOMMAND>
FLAGS:
--help Prints help information
-v, --version Prints version information
OPTIONS:
-h, --host <host> hostname the master mock server runs on (defaults to localhost)
-l, --loglevel <loglevel> Log level for mock servers to write to the log file (defaults to info) [values: error, warn,
info, debug, trace, none]
-p, --port <port> port the master mock server runs on (defaults to 8080)
SUBCOMMANDS:
create Creates a new mock server from a pact file
help Prints this message or the help of the given subcommand(s)
list Lists all the running mock servers
shutdown Shutdown the mock server by id or port number, releasing all its resources
start Starts the master mock server
verify Verify the mock server by id or port number, and generate a pact file if all ok
# The following options are available for all subcommands:
# This sets the host the master mock server runs on. By default this will be localhost.
# This sets the port that the master mock server runs on. By default this will be 8080. The start command will start the
master server using this port.
# This sets the log level that the CLI and mock servers log at. It defaults to info. Valid values are: error, warn,
info, debug, trace, none.
# # This prints either the main help or the help for a sub-command.
# This starts the master mock server. This server needs to be running for the other sub-commands to work.
