before - after

local tests:

Finished in 354.52 seconds
2361 specs, 0 failures

but I do see the

Warning: writing junit report failed for '', 'TEST-alloygenerate.xml'. Reasons:
  Rhino attempt: java is not defined
  PhantomJs attempt: window is not defined
  NodeJS attempt: ENOENT: no such file or directory, mkdir

messages too.
