Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest
    cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to
    transform your files, ignoring "node_modules".

    Here's what you can do:
    • To have some of your "node_modules" files transformed, you can
    specify a custom "transformIgnorePatterns" in your config.
    • If you need a custom transformation specify a "transform" option
    in your config.
    • If you simply want to mock your non-JS modules (e.g. binary
    assets) you can stub them out with the "moduleNameMapper" config
    option.

const esModules = ['@ionic', '@ionic-native',
'@angular/core'].join('|');

module.exports = {
 globals: {
  'ts-jest': {
    babelConfig: {
    presets: [
      [
        '@babel/preset-env',
        {
          targets: {
            node: true
          },
          modules: 'commonjs'
        }
       ]
      ],
      plugins: ['@babel/plugin-syntax-dynamic-import']
     }
    }
   },
   transformIgnorePatterns:
   [`<rootDir>/node_modules/(?!${esModules})`]
   };
