Patr (Promise-based Asynchronous Test Runner) is a simple lightweight cross-platform test runner for promised-based applications. Patr executes tests by simply executing functions of an object and is intended to be used in combination with the “assert” module (which is available on NodeJS and Narwhal), so tests can be as simple as:

var assert = require("assert");
tests = {
  testSomething: function(){
    assert.eq(3, 3);
  }
}
require("patr/runner").run(tests);
