configure .babelrc for react tape test

I want to add tape testing to my react/redux app. I can't find a way for my app to work both for testing and running. With this .babelrc configuration tests don't run but app works fine:

{
  "stage": 2,
  "env": {
    "development": {
      "plugins": [
        "react-transform"
      ],
      "extra": {
        "react-transform": {
          "transforms": [{
            "transform": "react-transform-hmr",
            "imports": ["react"],
            "locals":  ["module"]
          }]
        }
      }
    }
  }
}

With this .babelrc configuration tests work fine but npm start throws an error: Module build failed: ReferenceError: [BABEL]

{
  "presets": ["es2015", "react"]
}

How to merge those two files so that both running and testing would work?

Here is my package.json:

}

Here is the server.js:

var webpack = require('webpack')
var webpackDevMiddleware = require('webpack-dev-middleware')
var webpackHotMiddleware = require('webpack-hot-middleware')
var config = require('./webpack.config')

var app = new (require('express'))()
var port = 3000

var compiler = webpack(config)
app.use(webpackDevMiddleware(compiler, { noInfo: true, publicPath: config.output.publicPath }))
app.use(webpackHotMiddleware(compiler))

app.get("/", function(req, res) {
  res.sendFile(__dirname + '/index.html')
})

app.listen(port, function(error) {
  if (error) {
    console.error(error)
  } else {
    console.info("==> 🌎  Listening on port %s. Open up http://localhost:%s/ in your browser.", port, port)
  }
})

webpack.config.js:

var path = require('path')
var webpack = require('webpack')

module.exports = {
  devtool: 'cheap-module-eval-source-map',
  entry: [
    'webpack-hot-middleware/client',
    './index'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin()
  ],
  module: {
    loaders: [{
      test: /\.js$/,
      loaders: ['babel'],
      exclude: /node_modules/,
      include: __dirname
    }]
  }
}


// When inside Redux repo, prefer src to compiled version.
// You can safely delete these lines in your project.
var reduxSrc = path.join(__dirname, '..', '..', 'src')
var reduxNodeModules = path.join(__dirname, '..', '..', 'node_modules')
var fs = require('fs')

if (fs.existsSync(reduxSrc) && fs.existsSync(reduxNodeModules)) {
  // Resolve Redux to source
  module.exports.resolve = { alias: { 'redux': reduxSrc } }
  // Compile Redux from source
  module.exports.module.loaders.push({
    test: /\.js$/,
    loaders: ['babel'],
    include: reduxSrc
  })
}
