I am trying to dump out a few key measurements to console when my test runs, rather than getting them from the reporter output, but I can't see how to grab the time taken for the last step to execute. Here's a simplified version based on the docs for request.timing() but I don't think that what I'm doing is classed as a request:
const { test, expect } = require('@playwright/test');
test('ApplicationLoadTime', async ({ page }) => {
// Wait for applications to load
await page.waitForSelector('img[alt="Application"]');
// Not working! - get time for step execution
const [fir] = await Promise.all([
page.click('text=Further information requested'),
page.waitForSelector('img[alt="Application"]')
]);
console.log(fir.timing());
});
The click on "Further information requested" causes the page to be modified based on an AJAX call in the background and the appearance of the Application img tells me it's finished. Is this possible or do I need to rely on the reports instead?
fir is going to be undefined in your code as page.click() doesn't return anything. You need to wait for the request whose timing you're interested in, use page.waitForEvent('requestfinished') or waitForNavigation:
const { test, expect } = require('@playwright/test');
test('ApplicationLoadTime', async ({ page }) => {
// Wait for applications to load
await page.waitForSelector('img[alt="Application"]');
const [fir] = await Promise.all([
// Wait for the request
page.waitForEvent('requestfinished', r => r.url() == '<url of interest>'),
page.click('text=Further information requested'),
page.waitForSelector('img[alt="Application"]')
]);
console.log(fir.timing());
});
