Prior to working on porting to Bootstrap 4, it would be highly advisable to implement a set of functional tests in order to ensure the functionality is not broken.

This should also help uncover some of the more integration-related regressions down the line.

The following should be done:

• Implement functional tests:
  • Cover full website functionality.
  • If possible, this should include the changes to the admin interface - otherwise split this up into separate issue.
  • Use Selenium for testing.
  • Use geckodriver for interacting with the Firefox browswer.
  • Use Firefox as browser used for testing.
  • Local development binaries should be used for all purposes to avoid problematic interaction with distro-provided browser etc.
  • Make sure to use page objects to reduce code duplication.
• Implement additional miscellaneous tests as they crop up:
  • Implement tests for remaining custom template tags.
• Update development documentation:
  • Add small section describing how to get up-and-running with development environment.
  • Add instructions on how to download the necessary binaries, including geckodriver and Firefox.
  • All binaries should be placed somewhere within the development directory.
