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];
}

I found the error. It was because of some missing libraries need. I discovered this when I downgraded playwright to version 1.9 and ran the the code then this was the error msg:

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 }) => {});
});

I found the error. It was because of some missing libraries need. I discovered this when I downgraded playwright to version 1.9 and ran the the code then this was the error msg:

(node:12876) UnhandledPromiseRejectionWarning: browserType.launch: Host system is missing dependencies!

Some of the Universal C Runtime files cannot be found on the system. You can fix
that by installing Microsoft Visual C++ Redistributable for Visual Studio from:

A list of missing libraries was provided. After successful installments, firefox ran fine. I upgraded again to version 1.10 and firefox still works.

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
})

Top 17 Resources To Learn Test Automation

Lack of training is something that creates a major roadblock for a tester. Often, testers working in an organization are all of a sudden forced to learn a new framework or an automation tool whenever a new project demands it. You may be overwhelmed on how to learn test automation, where to start from and how to master test automation for web applications, and mobile applications on a new technology so soon.

How to Position Your Team for Success in Estimation

Estimates are critical if you want to be successful with projects. If you begin with a bad estimating approach, the project will almost certainly fail. To produce a much more promising estimate, direct each estimation-process issue toward a repeatable standard process. A smart approach reduces the degree of uncertainty. When dealing with presales phases, having the most precise estimation findings can assist you to deal with the project plan. This also helps the process to function more successfully, especially when faced with tight schedules and the danger of deviation.

Three Techniques for Improved Communication and Testing

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.

And the Winner Is: Aggregate Model-based Testing

In my last blog, I investigated both the stateless and the stateful class of model-based testing. Both have some advantages and disadvantages. You can use them for different types of systems, depending on whether a stateful solution is required or a stateless one is enough. However, a better solution is to use an aggregate technique that is appropriate for each system. Currently, the only aggregate solution is action-state testing, introduced in the book Paradigm Shift in Software Testing. This method is implemented in Harmony.
