我有这段代码：
nil我从以上例程中得到以下错误：
it('tests cookies', opts, async t => {
await driver.get(`${cdthost}/#!/my-acquisitions/${acqId}`).then(function () {
return Promise.delay(3000);
});
await driver.wait(until.elementLocated(By.id(`acq-dropdown-item-${acqId}`)), 4000).then(function () {
console.log(`acq-dropdown-item-${acqId} has been located.`);
});
let el = await driver.findElement(By.id(`acq-dropdown-item-${acqId}`));
console.log('el => ', el);
await el.click().then(() => Promise.delay(2000)).catch(function (e) {
console.error(' => Trapped click() error => ', e.stack || e);
});
return driver.getCurrentUrl().then(function (val) {
assert(val === `${cdthost}/#!/my-acquisitions/${acqId}`, 'We have a hella fast runner.');
})
.catch(function (err) {
console.error(' => Trapped getCurrentUrl() error => ', err.stack || err);
})
});
有谁知道为什么click（）会产生这样的错误？这是什么意思？我该如何解决？
当我记录 => Trapped click() error => WebDriverError:
