带有链接承诺的邮递员测试仅执行第一个承诺，而不执行链接承诺

Question

具有链接承诺的Postman测试仅执行第一个承诺，而不执行链接承诺

在Postman测试中，我按照下面的链接中的回答尝试了该解决方案，但是仍然只执行了第一个承诺，但没有获得链式承诺

How to use Promises in Postman tests?

// This timeout ensure that postman will not close the connection before completing async tasks.
//  - it must be cleared once all tasks are completed or it will hang
const interval = setTimeout(() => {}, Number.MAX_SAFE_INTEGER);

let promiseNumber = 0;

function resolvedPromise() {
    return new Promise((resolve, reject) => {
        pm.sendRequest('https://postman-echo.com/get', (err, res) => {
            if (err) {
                console.log(err);
                reject();
            } else {
                console.log(`Resolved promise ${++promiseNumber}`);
                resolve();

            }
        });
    });
}

resolvedPromise()
    .then(resolvedPromise)
    .then(resolvedPromise)
    .then(() => clearTimeout(interval))
    .catch(err => {
        console.log(err);
        clearTimeout(interval);
    });

在控制台上的预期结果将是：

Resolved promise 1
Resolved promise 2
Resolved promise 3

但我却收到：

Resolved promise 1
