此脚本正在登录站点。这是我的第一个笑话测试。测试前的最后一行单击 ul 下拉列表中的 li。然后我们导航到带有 url https://uat2.onplanapp.com/#/的新页面

作为一个简单的测试，我试图检查这确实是新页面的 url。当我在浏览器中观看时，脚本会登录并导航到正确的页面。

得到如下所示的错误。

代码

/**
 * @name Onplan Login
 * @desc Logs in and test for correct page title
 */
const puppeteer = require('puppeteer');
const assert = require('assert');
let browser;
let page;
beforeAll(async () => {
    browser = await puppeteer.launch({
        headless: false,
        devtools: true
        //slowMo: 50
    });
    const page = await browser.newPage();
    await page.goto('https://uat2.onplanapp.com/#/sheet/139');
    await page.waitFor(500);//was 500
    await page.waitFor('#inputEmail');
    await page.type('#inputEmail', 'xxx@yyy');
    await page.type('#inputPassword', '1111');
    await page.click('button');//Login
    await page.waitForNavigation();
    await page.waitFor(100);//was 500
    // SELECT COMPANY ON NEXT PAGE
    await page.waitFor('#logn-screenv > form > div.row.logn-screenbody.pb-4.pt-3.px-2 > div:nth-child(2) > div > div > div.css-1hwfws3.custom-scrollbar__value-container > div.css-151xaom-placeholder.custom-scrollbar__placeholder');
    await page.click('#logn-screenv > form > div.row.logn-screenbody.pb-4.pt-3.px-2 > div:nth-child(2) > div > div > div.css-1hwfws3.custom-scrollbar__value-container > div.css-151xaom-placeholder.custom-scrollbar__placeholder');//Login

    // SELECT COMPANY 
    await page.waitFor(500);// was 1000

    // click dropdown to show list of companies
    await page.click('#react-select-2-option-2'); //Test company
    await page.waitFor(300);//was 1000

    // click list item to select company
    await page.click('button[class="btn btn-block mt-3"]');
    // now navigate to company page


})

test('url should be correct"', async () => {

    expect.assertions(1);
    const url = await page.url;
    await assert(url === 'https://uat2.onplanapp.com/#/');
});



afterAll(async () => {
    //await browser.close()
})

这通常意味着在您的测试中没有停止异步操作。考虑运行 Jest--detectOpenHandles来解决此问题。 错误信息结束

我能够使用以下代码进行第一次测试。大部分问题是我在 beforeAll 中有代码，我需要进入测试。这是有效的代码。

 * @name Onplan Login
 * @desc Logs in and test for correct page title
 */
const puppeteer = require('puppeteer');
const assert = require('assert');
let browser;
beforeAll(async () => {
    browser = await puppeteer.launch({
        headless: false,
        devtools: false,
        slowMo: 50
    });

})

describe('url should be correct"', () => {
    test('url is correct', async () => {
        const page = await browser.newPage();
        await page.goto('https://uat2.onplanapp.com/#/sheet/139');
        await page.waitFor(500);//was 500
        await page.waitFor('#inputEmail');
        await page.type('#inputEmail', 'mayank@onplan.co');
        await page.type('#inputPassword', '123456');
        await page.click('button');//Login
        await page.waitForNavigation();
        await page.waitFor(100);//was 500
        // SELECT COMPANY ON NEXT PAGE
        await page.waitFor('#logn-screenv > form > div.row.logn-screenbody.pb-4.pt-3.px-2 > div:nth-child(2) > div > div > div.css-1hwfws3.custom-scrollbar__value-container > div.css-151xaom-placeholder.custom-scrollbar__placeholder');
        await page.click('#logn-screenv > form > div.row.logn-screenbody.pb-4.pt-3.px-2 > div:nth-child(2) > div > div > div.css-1hwfws3.custom-scrollbar__value-container > div.css-151xaom-placeholder.custom-scrollbar__placeholder');//Login

        // SELECT COMPANY 
        await page.waitFor(500);// was 1000

        // click dropdown to show list of companies
        await page.click('#react-select-2-option-2'); //Test company
        await page.waitFor(300);//was 1000
        await page.click('button[class="btn btn-block mt-3"]');
        //now we go to first page
        const url = await page.url();
        expect(url).toBe('https://uat2.onplanapp.com/#/');
