Testing changes · The measure · Element
The primary
The one measure the test is judged on.
The part
What it is
One. Secondary measures can be watched and cannot decide the outcome.
Chosen as the thing the change is actually meant to affect rather than the thing that is easiest to move.
The smallest level
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.
