Example Experiment

Hypothesis We can rollback changes to integration code, adapters, and configuration from version control.​ Experiment​

  • 1. Create a functional test integration
  • 2. Store it in a version control system
  • 3. Change the code and commit
  • 4. Revert to an older version.

Success Measure

  • We can pull changed code from version control.
  • We can browse the history of commits.
  • We can restore a random previous version.
