Just found that I couldn't do zeus c test for a test environment console Here's a workaround or small hack to do this Steps On your console do zeus init This will create two files zeus.json custom_plan.rb Add this snippet to your custom_plan.rb and define the tasks for Zeus. Mine looks like this: require 'zeus/rails' class CustomPlan Edit zeus.json to include only the tasks for which you’ll use Zeus. Mine looks like this: { "command": "ruby -rubygems -r./custom_plan -eZeus.go", "plan": { "boot": { "default_bundle": { "development_environment": { "prerake": {"rake": []}, "runner": ["r"], "console"
