Standalone Pact Stub Server

Build

This project provides a server that can generate responses based on pact files. It is a single executable binary. It implements the V4 Pact specification.

Docker Image

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.

Note: The stub server was designed to supporting prototyping of mobile applications by stubbing out the backend servers. It will always try to return a response, even when there is not an extract match with the pact files.

Command line interface

The pact stub server is bundled as a single binary executable pact-stub-server. Running this without any options displays the standard help.

$ pact-stub-server
Pact Stub Server 0.5.3

Usage: pact-stub-server [OPTIONS]

Options:
  -l, --loglevel <loglevel>
          Log level (defaults to info) [default: info] [possible values: error, warn, info, debug, trace, none]
  -f, --file <file>
          Pact file to load (can be repeated)
  -d, --dir <dir>
          Directory of pact files to load (can be repeated)
  -e, --extension <ext>
          File extension to use when loading from a directory (default is json)
  -u, --url <url>
          URL of pact file to fetch (can be repeated)
  -b, --broker-url <broker-url>
          URL of the pact broker to fetch pacts from [env: PACT_BROKER_BASE_URL=]
      --user <user>
          User and password to use when fetching pacts from URLS or Pact Broker in user:password form
  -t, --token <token>

  -p, --port <port>
          Port to run on (defaults to random port assigned by the OS)
  -o, --cors
          Automatically respond to OPTIONS requests and return default CORS headers
      --cors-referer
          Set the CORS Access-Control-Allow-Origin header to the Referer
      --insecure-tls
          Disables TLS certificate validation
  -s, --provider-state <provider-state>
          Provider state regular expression to filter the responses by
      --provider-state-header-name <provider-state-header-name>
          Name of the header parameter containing the provider state to be used in case multiple matching interactions are found
      --empty-provider-state
          Include empty provider states when filtering with --provider-state
      --consumer-name <consumer-name>
          Consumer name or regex to use to filter the Pacts fetched from the Pact broker (can be repeated)
      --provider-name <provider-name>
          Provider name or regex to use to filter the Pacts fetched from the Pact broker (can be repeated)
  -v, --version
          Print version information
  -h, --help
          Print help

Options

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. By default the Access-Control-Allow-Origin header will be set to *. If you provide the --cors-referer flag, then it will be set to the value of the Referer header from the request.

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
-b, --broker-url <url> URL Loads all the latest pacts from the Pact Broker

Note: For URLs and Pact Brokers that are authenticated, you can use the --user option to set the username and password or the --token to use a bearer token.

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.

Filtering interactions by consumer and provider name (Pact Broker)

For Pacts fetched from a Pact broker, you can filter the Pacts by the consumer and/or provider names using:

 --consumer-names <consumer-names>...
            Consumer names to use to filter the Pacts fetched from the Pact broker
            
 --provider-names <provider-names>...
            Provider names to use to filter the Pacts fetched from the Pact broker

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.

Running with docker

A docker image is published to pactfoundation/pact-stub-server.

Example of using it:

# Create a Stub API
docker pull pactfoundation/pact-stub-server
docker run -t -p 8080:8080 -v "$(pwd)/pacts/:/app/pacts" pactfoundation/pact-stub-server -p 8080 -d pacts

# Test your stub endpoints
curl -v $(docker-machine ip $(docker-machine active)):8080/bazbat
curl -v $(docker-machine ip $(docker-machine active)):8080/foobar
