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

- oHen siloed
- performance/penetra7on etc.

Takeaways
BDD has a broader
impact
Given/When/Then
is not a
discriminator
Test automation has
more applicable
domains
It’s not either/or.
The best teams
practice BDD
and
test automation
