An Approach to Developing and Testing Third Party JavaScript Widgets
summary
Shows a concrete workflow: use a Ruby script to build and minify the widget, run a proxy to intercept HTML responses and inject JS into HTML responses so tests run against real client pages. Uses Ruby Webrick proxy, Capybara and PhantomJS and mentions RSpec for regression suites. Demonstrates handling zipped responses, library conflicts and dynamic installs, and the proxy-based demo actually runs the widget on external pages so tests and client demos behave like live embeds.
