Continuous Integration on Drupal Projects

In the Amazee Labs web maintenance team, we have many projects that range in Drupal version – from 6 to 9. Some we built and some we inherited from other teams. To make sure that any work we do going forward does not create any issues, we make changes to codebases all the time, because assuming that everything will play nicely together when deployed can lead to problems and that leads to more time being spent fixing bugs.
