Feature: NPM notifies me when my dependencies are out of date
  In order to avoid accidentally running the tests against out of 
  date dependencies, npm should notify me when I try to do so.
  
  Scenario:
    Given I have a package.json that declares a dependency on [email protected]
    And I have run `npm install` and installed [email protected]
    And my coworker updates package.json to depend on [email protected]
    When I pull that change and run `npm test`
    Then I should get an error
    And my test script should not run

package.json

{
  ...
  "scripts": {
    "pretest": "npm ls --depth=Infinity > /dev/null",
    "test": "mocha or whatever"
  }
}

Thanks to @Mr0grog for the suggestion: https://gist.github.com/Mr0grog/9145413

Oh, cool, I didn’t even know "pretest" was a thing!
