assert.jsonFileContent testing if a key is set to anything.

[jhessin]

Hello,

I am new to unit testing but I want to check and make sure dependencies are being added properly by checking my package.json. I have this (coffeescript) code:

assert.jsonFileContent 'package.json',
  devDependencies:
    coffeescript: /\^\d\.\d\.\d/

to test if coffeescript is being added to the package.json, but it seems that this will always show up as true even if I intentionally break it. Is there a way to test if a key exists in a json file without knowing the exact value (as it changes regularly)?
