Mocha doesn't recognize dynamic imports

I'm using Mocha to test a react/webpack/babel application that is written in es6 stage-0 syntax, which includes dynamic imports. Webpack compiles it without errors, but mocha throws the following error when reaching a dynamic import syntax:

SyntaxError: Unexpected token import

The command that i'm running is:

$ mocha --compilers js:babel-register src/**/*.test.js

And in my
I have to following:

"presets": ["es2015", "react", "stage-0"]

As @louis has mentioned, this is a node issue. The solution is to add the dynamic-import-node plugin to babel:

  "presets": ["es2015", "react", "stage-0"],
  "plugins": ["dynamic-import-node"]

Which will add support for the import(...) syntax in node.
