A test that reproduces non-determisitic builds with browserify and react-loadable/split-require.
How to test:
npm install
npm test
The test script attempts to repeatedly make the build. As the output is always
expected to be 4 files, we detect a hash change by simply looking for there to
be more than 4 files in the bundle directory, this means a new hash was generated for the same files.
The file that changes represents the file comp3.jsx, which in turn, imports comp1.jsx and comp2.jsx, these last two are also imported by react-loadable in the main.jsx file.
