Task Summary
frontend/src/app/common/formly/formly-utils.ts (codecov ~16%) has pure helpers over FormlyFieldConfig arrays: getFieldByName, setHideExpression, and the createShouldHideFieldFunc predicate factory. Cover them with Vitest on plain objects (no TestBed). The rxjs createOutputFormChangeEventStream (debounce/distinct/share stream) is out of scope for this issue. See frontend/TESTING.md.
Behavior to cover
getFieldByName(name, fields) — returns the field whose key === name; undefined when no field matches; the first match when several share a keycreateShouldHideFieldFunc(...) — the returned predicate:
model is null/undefined -> returns false- target field value is
null/undefined -> returns hideOnNull
- regex mode -> hides iff the value matches
^(expected)$
- non-regex mode -> hides iff
value.toString() === expected
setHideExpression(toggleHidden, fields, hiddenBy) — sets hideExpression = hiddenBy on each named field that exists; no-op for names not present
