TestEachPublicFn [rule] v1.0.0

Any function or method exported from a module must have at least one corresponding test case. This is not 100% branch coverage — it is a baseline reachability requirement: every public contract must be exercised by at least one test.

Checks

• CI fails if a new exported function has zero test coverage (tracked by the coverage map).
• The test must call the function — not just import it.
• At minimum: one happy-path test. Edge cases (null input, boundary values) are expected but not enforced by this rule.
• React components: at least one render test (screen.getByRole or similar).

Label

Every exported function must have at least one test
