When factoring out "given"s (see Section 3.6, “Factor out common "Given"s”), or indeed when writing the "when"s and the "then"s, use a declarative style for the pages. The page should describe what it does, not how it does it.

For example, a good page would be "SetUpCountries". It's clear that this will set up all Country reference data classes. This could be included into a "SetUpReferenceData" page. For transaction data, we could have a page "JoeBloggsCustomer"; another one again could be "JoeBloggsFiveOrders".
