Active-Triples

  • It appears that ActiveFedora v8 (Fedora 4) uses ActiveTriples for handling of RDF.  Need to look at ActiveFedora code to confirm.
  • SOLR integration appears to be done in ActiveFedora, not ActiveTriples.  It will likely take a significant effort to move the SOLR integration out of ActiveFedora and into ActiveTriples.  Need to look at ActiveFedora code to make an estimate.
  • Hydra community is looking at putting RDF Access Control into ActiveFedora and thus Fedora, which complicates (to say the least) the removal of Fedora from the Hydra stack.

Testing and Debugging Gems  
  • factory_girl_rails - use to create users for testing
  • engine-cart - test apps that are engines (i.e., code that is not an app that can go inside a rails app) (ex. Sufia) - allows testing of the engine by providing a rails app
  • database_cleaner - used to clean out MySQL type databases
  • equivalent-xml - compare xml files - how similar are they - handy for testing datastreams
  • devise - ??? - uses Warden which is session manager - ex. login_as_user
  • byebug - debugger - pops you into shell at the point where you set a break point
  • pry - replaces rib with pry - good for debugging - cd into a module and look around
  • better_errors with binding_of_caller - pops up shell with all variables
Travis  
  • continuous integration system - runs tests every time you push to GitHub
  • fails if tests take longer than 50 min
  • can break out into sub-tests that will run concurrently
  • will launch dependencies
