Running mocha tests results in "Unexpected Reserved Word" error

STEP: npm test

ERROR: "Unexpected reserved word"

I had it before, and I don’t know anything that I changed, which could cause regression. When I start npm test, I get an "Unexpected Reserved Word" and point to an ES6 import statement. My understanding --compilers js:babel-registershould solve this problem.

I tried to install babel-coreboth globally and locally and use it instead babel-core/register. The same result.

Here is mine package.json.

{
  "name": "fresh",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "remotedev": "remotedev --hostname=localhost --port=8000",
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "mocha --compilers js:babel-register 'test/**/*.test.js'",
    "test:watch": "npm run test -- --watch --watch-extensions jsx"
  },
  "dependencies": {
    "immutable": "^3.7.6",
    "lodash": "^4.5.1",
    "ramda": "^0.19.1",
    "react-native": "^0.21.0",
    "react-native-router-flux": "^2.3.8",
    "react-native-sortable-listview": "0.0.5",
    "react-redux": "^4.4.0",
    "redux": "^3.3.1",
    "redux-saga": "^0.9.1",
    "reselect": "^2.0.3"
  },
  "devDependencies": {
    "babel-register": "^6.7.2",
    "chai": "^3.5.0",
    "chai-immutable": "^1.5.3",
    "mocha": "^2.4.5",
    "redux-devtools-filter-actions": "^1.1.0",
    "remote-redux-devtools": "^0.1.2",
    "remotedev-server": "0.0.3"
  }
}

Here are 2 tutorials indicating this should work.
