Simplify working with multiple domains

[romikoops]

Howitzer uses page object pattern. We do not need to specify protocol and host for each page class. Howitzer gets settings from default.yml (with prefix app_) and set hosts automatically. It works perfectly, until you do not need to test application with different domains. For that reason, howitzer provides site dsl method.

class FooPage < Howitzer::Web::Page
  site 'http://example.com'
end

In real life you deal with different environments and it is very important to keep the data as configurable. As a simple case, we could add new setting in default.yml

example_app_url=http://example.com

and then

class FooPage < Howitzer::Web::Page
  site Howitzer.example_app_url
end

Much better now, but what about ability to change it to https for example for staging environment and keep http for development one. Should not be a problem.

SEXY_SETTINGS="example_app_url=http://dev.example.com"
SEXY_SETTINGS="example_app_url=https://staging.example.com"

Ok, what about using basic authentication? Following code will work, but in some cases we need url without login and password in URL

SEXY_SETTINGS="example_app_url=https://user:pass@staging.example.com"

Then we could keep url parts separately and use addressable gem:

# default.yml
###########################################################
# EXAMPLE APPLICATION SETTINGS                                                                    #
###########################################################
 example_app_base_auth_login: login
 example_app_base_auth_pass: pass
 example_app_protocol: http
 example_app_host: example.com

# howitzer.rb
module Howitzer
 def self.example_app_uri
    ::Addressable::URI.new(
      user: Howitzer.example_app_base_auth_login,
      password: Howitzer.example_app_base_auth_pass,
      host: Howitzer.example_app_host,
      scheme: Howitzer.example_app_protocol || 'http'
    )
  end
end

# web/pages/foo_page.rb
class FooPage < Howitzer::Web::Page
  site Howitzer.example_app_uri.site
end

Huh, too big amount of code to deal with 1 additional url, is not it?

We need to find an approach how to simplify it. For example,

# howitzer.rb
module Howitzer
 def self.app_uri(name = nil)
    prefix = "#{name}_" if name.present?
    ::Addressable::URI.new(
      user: Howitzer.public_send("#{prefix}app_base_auth_login"),
      password: Howitzer.public_send("#{prefix}app_base_auth_pass"),
      host: Howitzer.public_send("#{prefix}app_host"),
      scheme: Howitzer.public_send("#{prefix}app_protocol") || 'http'
    )
  end
end

# web/pages/foo_page.rb
class FooPage < Howitzer::Web::Page
  site Howitzer.app_uri(:example).site
end
