jest: Test suite failed to run, SyntaxError: Unexpected token import

Question

This is my jest configuration from the package.json file:

\"jest\": {
    \"automock\": false,
    \"browser\": true,
    \"moduleNameMapper\": {
      \"\\\         


        

Answer 1

Each yearly preset only compiles what was ratified in that year. babel-preset-env replaces es2015, es2016, es2017, latest

Based on this, on latest configurations you must use/replace your Plugins/Preset of es2015 and any esX to the new one: env.

1. You must install babel-preset-env with npm install.
2. In your .babelrc you should update accordingly:

{
  "presets": [
    "env", 
    "stage-0", 
    "react-native"
  ],
  "plugins": ...
}

☝️ Remember the order of the plugins/preset in the array is important.
