no-snapshot-only-tests

Disallow tests whose entire assertion surface is snapshot matching.

Rule detailsโ€‹

Snapshots are useful regression aids, but a snapshot-only test often says little about the behavior that matters. The reader must inspect a generated artifact to understand the expected outcome, and broad snapshots can be updated without reviewing the semantic guarantee.

it("renders the error panel", () => {
    expect(renderErrorPanel({ code: "E_AUTH" })).toMatchSnapshot();
});

Correctโ€‹

it("renders the error panel", () => {
    const panel = renderErrorPanel({ code: "E_AUTH" });

    expect(panel.role).toBe("alert");
    expect(panel).toMatchSnapshot();
});

What this rule reportsโ€‹

This rule reports executable tests where every expect(...) assertion uses a snapshot matcher such as toMatchSnapshot() or toMatchInlineSnapshot().

Optionsโ€‹

This rule has no options.

When not to use itโ€‹

Disable this rule for intentionally visual snapshot suites that are reviewed through a separate snapshot approval workflow.
