Config

Copy the relevant section from package.json:

{
  "ava": {
    "babel": {
      "plugins": [
        "transform-es2015-modules-commonjs",
        "transform-flow-strip-types"
      ]
    },
    "require": [
      "babel-register"
    ]
  },
  "devDependencies": {
    "ava": "^0.17.0",
    "babel-cli": "^6.18.0",
    "babel-plugin-transform-es2015-modules-commonjs": "^6.18.0",
    "babel-plugin-transform-flow-strip-types": "^6.18.0",
    "babel-register": "^6.18.0",
    "sinon": "^1.17.6"
  },
  "private": true
}

Command-Line Arguments

Copy your npm build scripts or the ava command used:

ava --verbose ./test/EventEmitter/\#off.js

Environment

Tell us which operating system you are using, as well as which versions of Node.js, npm, and AVA. Run the following to get it quickly:

Node.js v7.1.0
darwin 16.1.0
0.17.0
4.0.2

@gajus thanks.

For others reading this issue, I implemented it the following way.

With my .babelrc file I specified two separate env objects — one that satisfies Rollup and one that satisfies AVA:

{
  "env": {
    "build": {
      "presets": [
        "stage-3",
        ["es2015", { "modules": false }]
      ]
    },
    "test": {
      "presets": [
        "stage-3",
        "es2015"
      ]
    }
  }
}

I then had two separate commands for building and testing:

BABEL_ENV=build npm run build
BABEL_ENV=test npm test

I have ended up using different .babelrc settings for development, production and testing.
