test-only-export

an export only its own tests reference

Deterministic checkadvisory by defaultbasetests

The argument

An export whose only references anywhere are test files is a hint, not a violation: production never calls it, so it may be dead code wearing a test — or a deliberate promotion whose contract the tests pin. The finding asks the question; a human answers it.

The proof

fail

export const buildGreeting = ({ name }: { name: string }): string => `Hello, ${name}.`;

pass

{
	"name": "test-only-export-pass-fixture",
	"private": true,
	"dependencies": {
		"@tanstack/react-router": "1.168.3",
		"@tanstack/react-start": "1.167.5"
	}
