/*
Scenario: App requests the user to provide accessors to an JSON object that they also provide.
e.g. User provides the following JSON object:
  { people: [ 
     { firstName: "Bob", lastName: "Jones" },
     { firstName: "Jane", lastName: "Jones" } 
    ], numbers: [1, 2, 3]
  }

The JSON object is saved to the 'data' variable by the app.

expect(_validationMessage).toBe('Invalid emails: ' + _badEmails.join(', ')

// However, the expect statement fails as validationMessage becomes:
'Invalid emails: bad@emails, roar@me, function () {
