Okey I have a huge problem trying to enable Jest on my React-native app. And every single answer from this topic gives me a different configuration for my webpack or my package.json. I hope to find an answer here.
For this simple test:
import 'react-native';
import React from 'react';
import Index from '../index.ios.js';
// Note: test renderer must be required after react-native.
import renderer from 'react-test-renderer';
it('renders correctly', () => {
const tree = renderer.create(
<Index />
);
});
I run: npm test and get:
SyntaxError: D:\workspaces\web\react\site\node_modules\react-native\jest\mockComponent.js: Support for the experimental syntax 'classProperties' isn't currently enabled (20:24):
With a lovely solution:
Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.
But I dont know how to do it.
This is my package.json configuration:

}
console.log('buildPath = ' + buildPath);
console.log('wpk_local_configuration = ' + JSON.stringify(wpk_local_configuration));
if (!fs.existsSync(buildPath)) {
fs.mkdirSync(buildPath);
}
fs.createReadStream(__dirname + "/components/parts/PDFViewer/configPDFViewer.js")
.pipe(fs.createWriteStream(buildPath + "/configPDFViewer.js"));
var _version = new Date().getTime();
console.log('version = ' + _version);
