Dependencies

• Ruby 2.2.3 (check out rbenv for a ruby version manager)
• phantomjs (assuming you have Hombrew, brew install phantomjs)
• bundler (gem install bundler)

Getting started

1. Make sure you have up-to-date gems: bundle
2. Execute the script by running: EMAIL=<your versionista email> PASSWORD=<your password> N=<number of hours back> INDEX=<starting index of csv> ruby capybara_script.rb
3. If the script completes successfully, you will have new csvs written in the output/ directory.

Extra

1. Sometimes the current page the script is scraping does not contain the expected html it is seeking. In these cases, Capybara will wait a set amount of time to see whether the content appears before giving up and throwing an error ( that we gracefully rescue for diff pages). The default time is 2 seconds. This number of seconds can me modified by passing the ENV variable "PAGE_WAIT_TIME" when executing the script. For example: PAGE_WAIT_TIME='1.5' or PAGE_WAIT_TIME=10 Beware that with too little a wait time, pages of the script besides the comparison pages may start failing.
