Karma ships each file as a separate script tag.  For some reason, Electron
eventually chokes with a network / insufficient resource error.

To sidestep, I concatenate all the tests into one file.

       'test/codegen/expect/language/sub/sub.js',
       'test/codegen/expect/language/*.lib',
       'test/browser/*.js',
       'test-main.js',
