How much of the personalised experience is actually tested.

What it is

Testing every combination is impossible past a small number of variants, which means most personalised experiences ship untested.

Which combinations are tested is a decision, and it is usually made by whichever ones are easy to reproduce.

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
