Jest + Playwright - Test callbacks of event-based DOM library
firefox browser does not start in playwright
Is it possible to get the selector from a locator object in playwright?
How to run a list of test suites in a single file concurrently in jest?

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
})

Native apps are developed specifically for one platform. Hence they are fast and deliver superior performance. They can be downloaded from various app stores and are not accessible through browsers.
One of the essential parts when performing automated UI testing, whether using Selenium or another framework, is identifying the correct web elements the tests will interact with. However, if the web elements are not located correctly, you might get NoSuchElementException in Selenium. This would cause a false negative result because we won’t get to the actual functionality check. Instead, our test will fail simply because it failed to interact with the correct element.
Smartphones have changed the way humans interact with technology. Be it travel, fitness, lifestyle, video games, or even services, it’s all just a few touches away (quite literally so). We only need to look at the growing throngs of smartphone or tablet users vs. desktop users to grasp this reality.
As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
