A Spec's row on the tests lens counts its exercised keyed rules

outcome

Execute a tests-lens row: the keyed rules an enabled example exercises against those it does not, and the unkeyed rules apart.

assumptions

• The world writes a root with one behavior Spec whose Behavior section holds two keyed rules and one unkeyed rule, and one example child that verifies it, exercising the first key, bound by a specTest anchor in a test file; it builds the page set and reads the Spec's row on the tests page.

Examples

Given a Spec with {keyed: 2} keyed rules and {unkeyed: 1} unkeyed rules
Given an example bound to a test anchor that exercises {exercised: 1} of those keyed rules
When the build renders the tests lens
Then the Spec's row reads {coverage: "1 of 2 keyed rules exercised"}
Then the Spec's row reads its verifier binding as {binding: "present"}
