Error with buble

[francoisromain]

Hello,
I try to setup tests with vue-jest. And there is the following error:

Object spread operator requires specified objectAssign option with 'Object.assign' or polyfill helper.
at Node.transpile (node_modules/vue-template-es2015-compiler/buble.js:12676:11)

In the webpack config there is a buble property (as explained here: https://github.com/vuejs/vue-loader/blob/master/docs/en/options.md#buble):

      test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          buble: {
            objectAssign: 'Object.assign',
            transforms: {
              stripWith: true
            }
          }
        }

Is there a way to pass the same option to Jest?
Thank you

I forgot to add "@babel/preset-stage-2" in babelrc. Sorry : )
