the solution I found was to update the zeus gem any version grater than 0.13.4.pre2
any of the upper commands works fine with me on version 0.14.0.rc1 and also on 0.13.4.pre2
version 0.13.4.pre2 works best with RAILS_ENV
, as of version 0.14.0.rc1 they suppressed executing test with RAILS_ENV
enabled
