Penny discusses her team's goal of creating automated end-to-end tests to test user journeys several times a day and prevent breaking changes. Their goal was to have a test suite of 80 automated tests integrated with their CI process and defect tracking by the end of the year, but they only achieved a test suite of 23 tests not fully integrated. Penny reflects on lessons learned around managing the learning curve, documentation, unexpected challenges, and accepting challenges to improve their automation efforts going forward.
