Standalone Pact Stub Server

Build Status Windows Build status

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.

Pact Stub Server

    pact-stub-server [FLAGS] [OPTIONS] --dir <dir>... --file <file>... --url <url>...

    -o, --cors            Automatically respond to OPTIONS requests and return default CORS headers
    -h, --help            Prints help information
        --insecure-tls    Disables TLS certificate validation
    -v, --version         Prints version information

    -d, --dir <dir>...                       Directory of pact files to verify (can be repeated)
    -f, --file <file>...                     Pact file to verify (can be repeated)
    -l, --loglevel <loglevel>                Log level (defaults to info) [possible values: error, warn,
                                             info, debug, trace, none]
    -p, --port <port>                        Port to run on (defaults to random port assigned by the OS)
    -s, --provider-state <provider-state>    Provider state regular expression to filter the responses by
    -u, --url <url>...                       URL of pact file to verify (can be repeated)
        --user <user>                        User and password to use when fetching pacts from URLS in user:password


Log Level

You can control the log level with the -l, --loglevel <loglevel> option. It defaults to info, and the options that you can specify are: error, warn, info, debug, trace, none.

CORS pre-flight requests

If you specify the -o, --cors option, then any un-matched OPTION request will result in a default 200 response.

Pact File Sources

You can specify the pacts to verify with the following options. They can be repeated to set multiple sources.

Option Type Description
-f, --file <file> File Loads a pact from the given file
-u, --url <url> URL Loads a pact from a URL resource
-d, --dir <dir> Directory Loads all the pacts from the given directory

Note: For URLs that are authenticated, you can use the --user option to set the username and password.

Disabling TLS certificate validation

If you need to load pact files from a HTTPS URL that is using a self-signed certificate, you can use the --insecure-tls flag to disable the TLS certificate validation. WARNING: this disables all certificate validations, including expired certificates.

Filtering interactions by provider state

You can filter the interactions by provider state by supplying the --provider-state option. This takes a regular expression that is applied to all interactions before the requests are matched.

Server Options

The running server can be controlled with the following options:

Option Description
-p, --port <port> The port to bind to. If not specified, a random port will be allocated by the operating system.
