How to run a list of test suites in a single file concurrently in jest?

Jest + Playwright - Test callbacks of event-based DOM library

firefox browser does not start in playwright

Running Playwright in Azure Function

Is it possible to get the selector from a locator object in playwright?

Assuming you are not running test with the --runinband flag, the simple answer is yes but it depends ????

There is a pretty comprehensive GitHub issue jest#6957 that explains certain cases of when tests are run concurrently or in parallel. But it seems to depend on a lot of edge cases where jest tries its best to determine the fastest way to run the tests given the circumstances.

To my knowledge there is no way to force jest to run in parallel.

Aside

Have you considered using playwright instead of puppeteer with jest? Playwright has their own internally built testing library called @playwright/test that is used in place of jest with a similar API. This library allows for explicitly defining test groups in a single file to run in parallel (i.e. test.describe.parallel) or serially (i.e. test.describe.serial). Or even to run all tests in parallel via a config option.

// parallel
test.describe.parallel('group', () => {
  test('runs in parallel 1', async ({ page }) => {});
  test('runs in parallel 2', async ({ page }) => {});
});

// serial
test.describe.serial('group', () => {
  test('runs first', async ({ page }) => {});
  test('runs second', async ({ page }) => {});
});

This question is quite close to a "need more focus" question. But let's try to give it some focus:

Does Playwright has access to the cPicker object on the page? Does it has access to the window object?

Yes, you can access both cPicker and the window object inside an evaluate call.

Should I trigger the events from the HTML file itself, and in the callbacks, print in the DOM the result, in some dummy-element, and then infer from that dummy element text that the callbacks fired?

Exactly, or you can assign values to a javascript variable:

const cPicker = new ColorPicker({
  onClickOutside(e){
  },
  onInput(color){
    window['color'] = color;
  },
  onChange(color){
    window['result'] = color;
  }
})

And then

it('Should call all callbacks with correct arguments', async() => {
    await page.goto(`http://localhost:5000/tests/visual/basic.html`, {waitUntil:'load'})

    // Wait until the next frame
    await page.evaluate(() => new Promise(requestAnimationFrame))

    // Act
   
    // Assert
    const result = await page.evaluate(() => window['color']);
    // Check the value
})

Well this is one way, but not sure if it will work for all possible locators!.

// Get a selector from a playwright locator
import { Locator } from "@playwright/test";
export function extractSelector(locator: Locator) {
    const selector = locator.toString();
    const parts = selector.split("@");
    if (parts.length !== 2) { throw Error("extractSelector: susupect that this is not a locator"); }
    if (parts[0] !== "Locator") { throw Error("extractSelector: did not find locator"); }
    return parts[1];
}

How To Refresh Page Using Selenium C# [Complete Tutorial]

When working on web automation with Selenium, I encountered scenarios where I needed to refresh pages from time to time. When does this happen? One scenario is that I needed to refresh the page to check that the data I expected to see was still available even after refreshing. Another possibility is to clear form data without going through each input individually.

Why Selenium WebDriver Should Be Your First Choice for Automation Testing

Developed in 2004 by Thoughtworks for internal usage, Selenium is a widely used tool for automated testing of web applications. Initially, Selenium IDE(Integrated Development Environment) was being used by multiple organizations and testers worldwide, benefits of automation testing with Selenium saved a lot of time and effort. The major downside of automation testing with Selenium IDE was that it would only work with Firefox. To resolve the issue, Selenium RC(Remote Control) was used which enabled Selenium to support automated cross browser testing.
