Alrighty, check it out.... I didn't do the extra credit (timer, wires).
Are we testing a bomb here or the LED output on a kids toy?

In all seriousness, the step descriptions are a prosaic description which you then provide the functionality for. There would be no harm here of instead saying something like `Then the bomb should go "boom"` ... it's a bit kooky, but imagine you're the villain (i.e. the stakeholder) writing the cukes that describe how the bomb should function.
