[MOB-TEST-01] Tripartite Naming: Follow Method_Scenario_ExpectedBehavior.[MOB-TEST-02] State & Component Invariant Rule: Assert on visible user outcomes and accessible UI elements; never inspect component internal state or props directly.[MOB-TEST-03] Entity Invariant Rule: Test calculations, validations, and domain invariants; ban trivial echo assertions.[MOB-TEST-04] Contract Testing Rule: Intercept network requests at HTTP boundary (MSW) or native module boundary; ban 1:1 pass-through mock echoing without contract assertions.[MOB-TEST-05] Bug-First Regression Lock: Every PR resolving a bug ticket or with title fix(...) must introduce a test reproducing the defect prior to the fix.@testing-library/react-native for user-centric tests. Mock native modules with jest.mock().test('increments counter on button press', () => {
const { getByText, getByRole } = render(<Counter />);
fireEvent.press(getByRole('button', { name: /increment/i }));
expect(getByText('Count: 1')).toBeTruthy();
});
getByRole, getByText over testID. Use findBy* for async elements.testID overuse.See references/testing-library.md for RNTL setup, mocking providers, and integration flow examples.
