I just called jest src/containers/components/VerificationView.test.js --runTestsByPath --verbose and it just has 1 simple test:
import React from 'react';
import { render, act, fireEvent, waitFor } from '@testing-library/react-native';
import VerificationView from './VerificationView';
describe('Verification Screen', () => {
beforeEach(() => {
jest.useFakeTimers();
});
afterEach(() => {
jest.runAllTimers();
})
it('should render without errors', async () => {
const verificationRes = {VerificationR: {status:1}};
const login = jest.fn();
const authContextValue = { login }; // Mock the context value
var wrapper = render(
<VerificationView />
);
await wrapper.update();
expect(wrapper).toMatchSnapshot();
});
});
but the test run calls many other files:
PASS src/containers/components/VerificationView.test.js

And a snip from my jest.config.js
