Imagine it's 1922
Most software does something people could do manually (just not as efficiently).
Try hard to come up with examples that don’t make any assumptions about technology. Imagine it’s 1922, when there were no computers.
Good BDD examples are concrete rather than abstract. They mention names of people and places, exact dates and amounts, and anything that is relevant to the problem domain of the software.
Good examples don’t mention technical details.
