如何检查该TextInput
组件是否聚焦?我知道如何在网上做到这一点:
const input = getByPlaceholderText("placeholder");
expect(document.activeElement).toEqual(input);
但是如何在 React Native 中做同样的事情呢?
it('should have focus', () => {
const { getByTestId } = render(<TextInput autoFocus testID={ 'alpha' }/>);
const textInput = getByTestId('alpha');
// and then ..?
});
