I am using the NumericInput and it works fine when I run the application on my device.
However, when I run jest
, I get all kind of errors:
TypeError: Cannot read property 'default' of undefined

Consider adding an error boundary to your tree to customize error handling behavior.

First question: Is that normal?
Second question: If it is, how do I mock NumericInput
?
Following this guide, it seems I need to do:
jest.mock('react-native-numeric-input', () => 'NumericInput');
But it doesn't work. I also tried:
jest.mock('react-native-vector-icons', () => 'Icon');
With no success.
What is going on here o_0?
Cheers!
