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

Jest sets the env variable to test, so I had to add my presets to the env setting in .babelrc:

{
  "plugins": ["syntax-dynamic-import", "transform-runtime"],
  "presets": [
    [
      "es2015",
      {
        "modules": false
      }
    ],
    "react",
    "stage-0"
  ],
  "env": {
    "start": {
      "presets": [
        "react-hmre"
      ]
    },
    "test": {
      "presets": ["es2015", "react", "stage-0"]
    }
  }
}
