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

Running Playwright in Azure Function

firefox browser does not start in playwright

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

firefox browser does not start 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
})

June ‘21 Updates: Live With Cypress Testing, LT Browser Made Free Forever, YouTrack Integration &#038; More!

Howdy testers! June has ended, and it’s time to give you a refresher on everything that happened at LambdaTest over the last month. We are thrilled to share that we are live with Cypress testing and that our very own LT Browser is free for all LambdaTest users. That’s not all, folks! We have also added a whole new range of browsers, devices & features to make testing more effortless than ever.

Do you possess the necessary characteristics to adopt an Agile testing mindset?

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.

How To Test React Native Apps On iOS And Android

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.

QA Management &#8211; Tips for leading Global teams
