Question

我正在使用CodeceptJS编写测试以检查事务是否已成功注册：

const { I, signInPage, helpers } = inject();

const util = require('util');
var Request = require("request");

const requestPromise = util.promisify(Request);

function sleep(seconds) 
{
return new Promise((resolve) => {
    setTimeout(resolve, seconds * 1000);
});
} 

async function getNumberOfTransactions()
{
var result = await requestPromise('http://my.service.com/trans_count.php?user_id=12345');
return JSON.parse(result.body).transactions;
}


Scenario('My Test', async () => 
{
    I.amOnPage('some-page');
    // ...
    // Perform an online transaction...
    // ...
    I.see('Transaction successful');
    
    var attempts = 0;
    var current_transaction_count = await getNumberOfTransactions();
    while (current_transaction_count < expected_transaction_count && attempts < 60) {
        await sleep(60);
        I.say('Current transaction count: ' + current_transaction_count + ', expected transaction count: ' + expected_transaction_count);
        current_transaction_count = await getNumberOfTransactions();
        attempts++;
    }

    I.assertEqual(
        expected_transaction_count, 
        current_transaction_count, 
        "********** Transaction not tracked after one hour **********"
    );

}

我的问题是，当页面上没有“交易成功”时，行I.see('Transaction successful');不会停止脚本执行。相反，我在输出中得到了这个

(node:48370) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:48370) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

我不精通JavaScript / NodeJS，因此请在“入门”中进行解释：）

CodeceptJS I.see（）在失败时不停止脚本执行
