示例1: function
QUnit.test('debounce without a target, with args - can be canceled', function(assert) {
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 bar = { isBar: 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);
bb.debounce(target2, method, arg1, arg2, 1000);
debugInfo = bb.getDebugInfo();
resetError();
assert.deepEqual(debugInfo.timers,
[
{
args: [arg1],
method,
stack: oneStack,
target: target1
},
{
args: [arg1, arg2],
method,
stack: twoStack,
target: target2
}
]
, 'debugInfo is output');

let done = assert.async();
let bb = new Backburner(['one']);
let laterWasCalled = false;
let debounceWasCalled = false;
