Thanks for the demo. Really helpful for the beginners. One thing I saw while reading react-native-testing-library docs is, it states that it is a replacement for Enzyme here.

So do we really need to add Enzyme to replicate your tutorial? I haven't actually started to write my tests yet.

In Login.js
i use text.replace(/[^0-9]/g, '') get number from text set to phone number.

and test changeText phone:

    it('change text is string to phone input ', () => {
      const { getByTestId } = render(<Login />);

      fireEvent.changeText(getByTestId('phone'), 'isstring');

      expect(getByTestId('phone').props.value).toEqual('');
    });

How to improve it use jest or lib other ?

What is the current behavior?

If there is test code that should be wrapped in act(...) then the current warning is given:

 console.error node_modules/react-dom/cjs/react-dom.development.js:506
    Warning: An update to null inside a test was not wrapped in act(...).

    When testing, code that causes React state updates should be wrapped into act(...):

    act(() => {
      /* fire events that update state */
    });
    /* assert on the output */

    This ensures that you're testing the behavior the user would see in the browser. Learn more at https://fb.me/react-wrap-tests-with-act

i config in jestSetup.js hidden it

How to fix it ?.
