JSON Brutalize

Provided a fully-populated JSON object, Brutalize will generate an array of possible variations to that object. Useful for hardening your templates against potentially volitile API data.

Usage

Install:

  npm install json-brutalize

Methods:

• generate(JSON, depth, typeCheck)
  • JSON: The fully-populated JSON object to generate variations against.
  • depth: (optional) The maximum number of decendents generate will attempt to delete. If omitted, will attempt the maximum number of variations (equal to the number of endpoints in JSON).
  • typeCheck: (optional) generates clones where elements are replaced by different types of valid JSON objects.

Example:

  var fixture = {
    "foo": "bar",
    "baz": {
      "a": 1,
      "b": 2
    }
  };

  var Brutalize = require('json-brutalize');

  var output = Brutalize.generate(fixture, 1); // Returns array of length 5.
  var output2 = Brutalize.generate(fixture, 2); // Returns array of length 9.
  var output3 = Brutalize.generate(fixture); // All possible variations of `fixture`. Returns array of length 10.
  var output4 = Brutalize.generate(fixture, 2, true); // Returns array of length 179.

TODO:

• It's easy for the process to max out RAM, particulary for very complicated JSON files with a depth > 1. In lieu of a "real" solution for this, I should at least let the generator close down if it becomes sufficiently slow, and perhaps randomize the output between depths so that you can at least get a random sampling.
• Per the above, it might make more sense to set a "max tests" option.
