The Drupal content management system is one of the most popular engines for dynamic websites — indeed, it powers the site you're visiting right now. All this powering doesn't happen by itself, though, and the developer community that does the dirty work behind the scenes is in need of a bit of Linux labor.
The Testing and Quality Assurance team at Drupal are "the plumbers who keep the community plumbing from leaking." While they once spent their time reviewing patches one-by-one to assure stability, they now employ a testing bot to automatically apply patches to test installations, freeing up tester time to tackle greater things.
All this wrangling and testing requires time and energy from the wranglers of course, and equally important, it requires resources.
