Might one import a library that generates "acceptable" emails, keys, passwords, etc, that get assigned during the tests a runtime?

I'm imagining:
```coffee
magic_data = require `magic-data` # (named for magic numbers)
user =  
  _id : magic_data.mongodb.object_id()
  name : magic_data.username()
  email : magic_data.email()
```

This assumes that the tests don't rely on any specific strings. Also would potentially require that data is generated consistently (if tests are async).

It looks like there are a number of packages for generating test data -- curious if any of these would simplify life for the developer.
