This page is a reference to the crate; how tests use it is in Lecture 40.

Test-only steps that give a program what an operation’s tests build on, without sketching and extruding it: Primitive, a solid at given coordinates — a block, a prism, a cylinder or a sphere, kept as a new body or combined with a solid of the part as a step’s Combine says — and GivenDatum, a point, an axis, a plane or a coordinate system at given coordinates. Both are ordinary serializable steps, so a program in an editor’s timeline can hold them and a part the front end clicks on can be built from them; no editor offers them.

An operation’s tests take the crate as a dev-dependency and register the two steps in the registry of their programs (registry) or of their editor (register). drilled_box is the box with a blind hole the hand-written tests cut, round and inspect; bodies holds the boxes, cylinders and spheres, whole, drilled, pocketed, stepped and with a boss, that the stress sweeps of blends and shells run over.

The crate exists so that a change to the sketch or the extrude operation retests those crates and the composition, not every crate whose tests start from a block: a test that needs a solid starts from a Primitive, one that checks how its operation meets an extrusion as such keeps depending on geop-ops-extrude-revolve.
