我可以设置剧作家浏览器的日期吗

Question

当我编写要在 playwright 中运行的测试时，我希望能够设置浏览器认为测试开始的日期。有没有办法使用剧作家来实现这一点？

您可以使用TimeShift等模拟工具。这段代码将注入时移库，然后注入日期Feb 02 2012：

const playwright = require("playwright");

(async () => {

    let removed = false;
    const browser = await playwright["chromium"].launch({headless: false});
    const page = await browser.newPage();
    await page.setContent('<a href="#" onclick="document.querySelector(\'span\').innerText = new Date().toString()">Test me</a><span></span>');
    await page.click('a');
    console.log(await page.innerText('span'));
    await page.addScriptTag({ url: 'https://cdn.jsdelivr.net/npm/timeshift-js@1.1.1/timeshift.js'});
    await page.evaluate(() => {
        Date = TimeShift.Date; 
        TimeShift.setTime(1328230923000); 
    });
    await page.click('a');
    console.log(await page.innerText('span'));
    browser.close();
})();

输出：

Fri Sep 18 2020 15:06:58 GMT-0300 (Argentina Standard Time)
Thu Feb 02 2012 22:02:03 GMT-0300
