Living with Acceptance Tests: Beyond Write-Once

Please log in to watch this conference skillscast.

Acceptance tests have become a common part of building software for an agile process. However, I've observed a trend of growing build times - with teams saying "Our build is 15 minutes... well, actually it's 45 minutes because our Cucumbers took so long, so we parallelized the cukes." One reason for this may be that teams treat their acceptance tests as "Write-Once": create for a new story, get them to pass, and leave them be. In this talk we'll explore the technical and social forces that cause an acceptance test suite to grow, and discuss some ways to refactor and improve these tests. We'll touch on hexagonal architecture, declarative vs. imperative style, and alternate Cucumber step implementations.
