Programming

I've released NonMockObjects 0.2.0.

This release adds easy support for obtaining many variants of an object, which allows you to easily test that all combinations of some parameters have a certain invariant.

For instance, my Entry objects for this weblog can optionally contain a title, a link for the title, and a summary. The only constraint on that set is that a link affects a title, so you really need a title for the link to make sense, although it is permissible to have a link without a title in the database. By setting up my Entry creation function to indicate that each of those can either be None or contain a certain concrete string, I can obtain all 8 combinations of an entry with:

    for entry in data.variations_entry():

I'm a little late to this party; only today and to a lesser degree yesterday is my typing speed high enough that I feel I can "afford" a weblog post... and even this otherwise pointless paragraph :-) (My previous post on switching to Dvorak was justified as a typing exercise and easily took over two hours to type. This one did too in rough draft but you see how much better I'm doing :-) )
