  let done = assert.async();
  let bb = new Backburner(['batman']);
  let calledCount = 0;
  let calledWith: object[] = [];
  function debouncee(first) {
    calledCount++;
    calledWith.push(first);
  }

  let foo = { isFoo: true };

  let baz = { isBaz: true };
  bb.debounce(debouncee, foo, 10);
  bb.debounce(debouncee, bar, 10);
  let timer = bb.debounce(debouncee, baz, 10);
  assert.equal(calledCount, 0, 'debounced method was not called immediately');

  setTimeout(() => {
    assert.deepEqual(calledWith, [], 'debounce method has not been called on next tick');
    bb.cancel(timer);
  }, 0);

  setTimeout(() => {
    assert.deepEqual(calledWith, [], 'debounce method is not called when canceled');
    done();
  }, 20);

示例2: resetError

  bb.run(function() {
    bb.debounce(target1, method, arg1, 1000);

    debugInfo = bb.getDebugInfo();

    resetError();

    assert.deepEqual(debugInfo.timers,
    [
      {
        args: [arg1],
        method,
        stack: oneStack,
