Webpack build process not failing testem

[jehoshua02]

Not sure if this is on testem side or webpack side but running build in the absence of appropriate loaders, causing the webpack build process to file, isn't being acknowledged by testem, giving a false impression of positive results.

To reproduce:

git clone https://github.com/jehoshua02/testem-example.git
cd testem-example
git checkout e2dc6f53820355b20ffaf10eece4774809ddc66f
npm install
`npm bin`/webpack --config ./tests/webpack.config.js
npm test

I get the following output on running webpack:

~/projects/jehoshua02/testem-hello-world 🚀  babel [!$]
$ `npm bin`/webpack --config ./tests/webpack.config.js

You may need an appropriate loader to handle this file type.

When when I run testem, everything looks fine. But I notice there are only 3 tests when I am expecting 4.
