Module: ServiceBureau::Services

Defined in:
lib/service_bureau/services.rb

Overview

When mixed in to a class, it provides a handle for all configured services. It also provides an injector method for each service so that altenative implementations can be easily injected e.g. for testing.

Examples:

ServiceBureau::Locations.configure do |c|
  c.my_service MyService.public_method(:new)
end

Class MyClass
  include ServiceBureau::Services
end

obj = MyClass.new
obj.my_service # => returns the result of: MyService.new

obj.my_service = double('a fake service')
obj.my_service # => returns the test double
