@sam, what are your thoughts on setting up dir structure for a chimp setup. Is it best to do like you did at https://github.com/xolvio/automated-testing-best-practices where the actual Meteor app is in a subfolder like src? Or is it possible to set it up at the same root level?
You can put it anywhere you like and use the --path and -r (or --require) options to tell Chimp where the files are.
If you want to use your Meteor directory, you can put the files under /tests and Meteor will ignore them. This may change in 1.3 so you may need to change that again
