Jest + Playwright - Test callbacks of event-based DOM library
Is it possible to get the selector from a locator object in playwright?

firefox browser does not start in playwright
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
})

Building a website is all about keeping the user experience in mind. Ultimately, it’s about providing visitors with a mind-blowing experience so they’ll keep coming back. One way to ensure visitors have a great time on your site is to add some eye-catching text or image animations.
As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers. Even if it is supported, the feature might be experimental and not work consistently across all browsers. Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????
As everyone knows, the mobile industry has taken over the world and is the fastest emerging industry in terms of technology and business. It is possible to do all the tasks using a mobile phone, for which earlier we had to use a computer. According to Statista, in 2021, smartphone vendors sold around 1.43 billion smartphones worldwide. The smartphone penetration rate has been continuously rising, reaching 78.05 percent in 2020. By 2025, it is expected that almost 87 percent of all mobile users in the United States will own a smartphone.
To understand the agile testing mindset, we first need to determine what makes a team “agile.” To me, an agile team continually focuses on becoming self-organized and cross-functional to be able to complete any challenge they may face during a project.
