Working on a medium Angular 8 app where "shipping software" was prioritized over "shipping tested software." Most of the unit tests are either the bare-bones shell cranked out by the CLI or are skipped/commented out.

E - No unit test file exists for that component.

D - Only the CLI-generated spec.ts file exists.

C through A - Each testable method (public with return type) has a test, each HTML element with an ID has a test, etc.
