Custom Connections

Set EasyPost.default_connection to an object that responds to call(method, path, api_key = nil, body = nil)

Faraday

require 'faraday'
require 'faraday/response/logger'
require 'logger'

EasyPost.default_connection = lambda do |method, path, api_key = nil, body = nil|
  Faraday
    .new(url: EasyPost.api_base, headers: EasyPost.default_headers) { |builder|
      builder.use Faraday::Response::Logger, Logger.new(STDOUT), {bodies: true, headers: true}
      builder.adapter :net_http
    }
    .public_send(method, path) { |request|
      request.headers['Authorization'] = EasyPost.authorization(api_key)
      request.body = JSON.dump(EasyPost::Util.objects_to_ids(body)) if body
    }.yield_self { |response|
      EasyPost.parse_response(
        status: response.status,
        body: response.body,
        json: response.headers['Content-Type'].start_with?('application/json'),
      )
    }
end

Typhoeus

require 'typhoeus'

EasyPost.default_connection = lambda do |method, path, api_key = nil, body = nil|
  Typhoeus.public_send(
    method,
    File.join(EasyPost.api_base, path),
    headers: EasyPost.default_headers.merge('Authorization' => EasyPost.authorization(api_key)),
    body: body.nil? ? nil : JSON.dump(EasyPost::Util.objects_to_ids(body)),
  ).yield_self { |response|
    EasyPost.parse_response(
      status: response.code,
      body: response.body,
      json: response.headers['Content-Type'].start_with?('application/json'),
    )
  }
end

Testing

The test suite in this project was specifically built to produce consistent results on every run, regardless of when they run or who is running them. This project uses VCR to record and replay HTTP requests and responses via "cassettes". When the suite is run, the HTTP requests and responses for each test function will be saved to a cassette if they do not exist already and replayed from this saved file if they do, which saves the need to make live API calls on every test run.

Sensitive Data: We've made every attempt to include scrubbers for sensitive data when recording cassettes so that PII or sensitive info does not persist in version control; however, please ensure when recording or re-recording cassettes that prior to committing your changes, no PII or sensitive information gets persisted by inspecting the cassette.

Making Changes: If you make an addition to this project, the request/response will get recorded automatically for you. When making changes to this project, you'll need to re-record the associated cassette to force a new live API call for that test which will then record the request/response used on the next run.

Test Data: The test suite has been populated with various helpful fixtures that are available for use, each completely independent from a particular user with the exception of the USPS carrier account ID (see Unit Test API Keys for more information) which has a fallback value of our internal testing user's ID. Some fixtures use hard-coded dates that may need to be incremented if cassettes get re-recorded (such as reports or pickups).

Unit Test API Keys

The following are required on every test run:

  • EASYPOST_TEST_API_KEY
  • EASYPOST_PROD_API_KEY

Some tests may require an EasyPost user with a particular set of enabled features such as a Partner user when creating referrals. We have attempted to call out these functions in their respective docstrings. The following are required when you need to re-record cassettes for applicable tests:

  • USPS_CARRIER_ACCOUNT_ID (eg: one-call buying a shipment for non-EasyPost employees)
  • PARTNER_USER_PROD_API_KEY (eg: creating a referral user)
  • REFERRAL_USER_PROD_API_KEY (eg: adding a credit card to a referral user)
