cukeup nyc richard lawrence on getting the language right
DESCRIPTION
Getting the Language Right One of the most powerful things Cucumber can do for a software team is help them grow a ubiquitous language. But this depends on scenarios having the right level of detail at the right level of abstraction to be expressive to business people, testers, and developers alike. In this session, we'll look at the range of language that shows up in Cucumber scenarios in order to identify the sweet spot of just enough detail, just enough abstraction. You'll get hands-on with example scenarios and learn how to identify the same patterns in your own scenarios.TRANSCRIPT
