In the world of automation testing, generating realistic-looking test data is a preferred approach to using static fixtures. FakerMaker is a Ruby gem that allows you to do just that; using factories to create the test data you need. It can be used with Faker to dynamically generate test data. Initialisation We can use Faker and FakerMaker to create a factory for an API request body like this: require 'faker' require 'faker_maker' FakerMaker.factory :example_request, naming: :json do name { Faker::Name.name } building_number { Faker::Address.building_number } street_name { Faker::Address.street_name } city { Faker::Address.city } country { Faker::Address.country } end Which can be called to create a request body like this: ...

If you want to change the stream that this Ruby process sends its output to, you can change the value of $stdout Hello StringIO Given an RSpec test pack, I should be able to use an output matcher, but I couldn’t get this to reliably work across tests for my system. However, the standard library includes an IO-like object for strings, StringIO, which must be explicitly required. ...
