示例1: test_clearInterval_immediatelyAfterCreate
export function test_clearInterval_immediatelyAfterCreate() {
let completed = false;
const id = timer.setInterval(() => {
completed = true;
});
timer.clearInterval(id);
TKUnit.wait(0.05);
TKUnit.assert(!completed, "Callback should not be called");
}示例2: test_setInterval_callbackShouldBeCleared
export function test_setInterval_callbackShouldBeCleared(done) {
let counter = 0;
const start = TKUnit.time();
// >> timer-set-interval
const id = timer.setInterval(() => {
// >> (hide)
const end = TKUnit.time();
timer.clearInterval(id);
done(end - start > 150 ? new Error('setInterval too slow.') : null);
// << (hide)
timer.clearInterval(id);
}, 50);
// << timer-set-interval
};示例3: test_setInterval_callbackCalledWithExtraArgs
export function test_setInterval_callbackCalledWithExtraArgs(done) {
