The document discusses the differences between test automation and behaviour-driven development (BDD). It defines test automation as using separate software to control test execution and compare results, while BDD creates shared understanding of requirements through structured conversations and examples documented in business language. Key differences are that BDD has broader impact through living documentation, whereas test automation has more applicable testing domains but may be siloed; both provide benefits like quality and feedback if practiced effectively together. The document warns against confusion that BDD is the same as test automation or that using Given/When/Then implies following BDD.

1. Are BDD and Test Automation the same thing?

Define test automation
“… test automation is the use of
software separate from the software
being tested to control the execution
of tests and the comparison of
actual outcomes with predicted
outcomes.”

Define BDD
Create a shared understanding of the
requirements through collabora7on, typically
achieved through a structured conversa7on
centered on rules and examples
Examples of system behaviour are
documented using business terminology
The documenta7on is automated, crea7ng
living documenta7on that verifies the
system’s behaviour

Test automation has

It’s not either/or.
