Recipe for using AVA with Webpack aliases

I use Webpack in my app and I defined aliases in config: webpack.config.dev.js:

....
resolve: {
    // We can now require('file') instead of require('file.jsx')
    extensions: ['', '.js', '.jsx', '.scss'],
    alias: {
      actions: PATHS.app + '/actions',
      components: PATHS.app + '/components',
      store: PATHS.app + '/store',
      reducers: PATHS.app + '/reducers',
      helpers: PATHS.app + '/helpers',
      sagas:  PATHS.app + '/sagas',
      services:  PATHS.app + '/services',
    },
  }
....

And I import modules like so: componts/LoginPage.js

import {login} from 'actions/Login'

instead of

import {login} from '../actions/Login'

But AVA doesn’t allow to define aliases, so I’m unable to test componts/LoginPage.js with AVA since it throws that error:

Error: Cannot find module 'actions/Login'

Is there a solution?

Thank you, guys for your help. It seems to work with following configs:

config/webpack.config.ava.js

const path = require('path');

const PATHS = {
  app: path.resolve(__dirname, '../src'),
};

module.exports = {
   resolve: {
     modulesDirectories: [
       __dirname,
      'node_modules',
       PATHS.app,
     ]
   },
   module: {
     loaders: [
       {
         test: /\.css$/,
         loader: 'style-loader!css-loader?modules&importLoaders=1!postcss-loader',
       },
     ]
   }
};

package.json

{
  ....
  "scripts": {
    "test": "CONFIG=$(pwd)/config/webpack.config.ava.js BABEL_DISABLE_CACHE=1 NODE_ENV=AVA ava" 
    },
  ....
  "ava": {
    "files": [
      "src/**/*.spec.js"
    ],
    "require": [
      "babel-register"
    ],
    "babel": "inherit"
  }
}

.babelrc

{
  "presets": ["es2015", "react", "stage-1", "stage-0"],
  "env": {
    "AVA": {
      "plugins": [
        [
          "babel-plugin-webpack-loaders",
          {
            "config": "${CONFIG}",
            "verbose": false
          }
        ]
      ]
    }
  }
}

Btw, I have another solution of my problem (without using webpack):

env NODE_PATH=src ava
