Dirty self-rolled assert

function assert (actual, expected, msg, su) {
  if (!window.assertions) {
    window.assertions = {success:0, fail:0};
  }
  if (expected !== actual)  {
    var message = msg || 'expected ' + expected + ' but got ' + actual;
    console.warn(message);
    window.assertions.fail = window.assertions.fail +1
  } else {
    window.assertions.success = window.assertions.success +1;
    console.log('success');
  }
}

function report(){
  if (window.assertions.success > 0 && window.assertions.fail === 0) {
    console.log('ALL ' + window.assertions.success + ' TESTS PAAASSSEEEEED!!!' )
  } else {
    console.warn(  window.assertions.success + ' / ' + (window.assertions.fail + window.assertions.success) + ' passed' )
  }
