Accord

Accord is a super simple consumer contract testing and stubbing tool, that is language agnostic.

Getting Started

Prebuilt binaries can be downloaded here, however if you wish to build from source you will need go 1.7+

Installing

go get github.com/ChrisMcKenzie/accord

Writing a contract

A contract is defined by creating a accord.hcl file containing an "endpoint" like the following.

endpoint "/users" {
  method = "POST"

  request {
    body = <<-EOF
    {
      "test": "value"
    }
    EOF
  }

  response {
    code = 201

    body = "hello, world"
  }
}

this will define a stub/test-client at the url /users that will respond/request with a POST method and the specified response/request data.

For the case of testing a provider with the "consumer" contract you can import contracts from git, s3, http, local, and mercurial by adding the following to an accord.hcl.

accord "test-accord" {
  source = "github.com/ChrisMcKenzie/accord//examples/test.hcl"
}

You can create multiple accord definitions and they will all be pulled and merged in to a single suite for serving and testing.

Running A Stub Server

Accord can be used to run a stub/mock server based on the endpoints in your accord.hcl. This can be done by running the following.

accord serve
Loaded the following endpoints from examples/accord.hcl

Module root:
        ENDPOINT: [GET] /users
Module test-accord:
        ENDPOINT: [POST] /users

this will start a web server listening on localhost:7600 the port can be changed by using the -p flag.
