In the software development life cycle, a shift in testing gained popularity with respect to the increase in the number of testing frameworks.

Among those, Playwright cross-browser testing framework is an efficient and comprehensive solution for web testing. It allows developers to ensure that their websites are fully compatible with a range of browsers and platforms.

Playwright being one of the best options for cross-browser testing is routinely introduced into the market.

According to GitHub, the Playwright framework is gaining popularity with 39.3k Star, 1.8k Fork, and 12.2k Active Users.

In the search for writing reliable and scalable fast test automation, the Playwright automation framework streamlines cross-browser testing.

In this blog post, we will explore the basics of using Playwright for cross-browser testing, including how to get started and the key features of the platform.

With the help of Playwright, developers can rest assured knowing that their websites are compatible with all major browsers and platforms.

So let’s get started!

What is Playwright?

Playwright is a Node.js library that helps developers automate the end-to-end testing of web applications.

Developed by the Microsoft Edge team, Playwright is a powerful framework that enables developers to write tests that are more reliable and easier to maintain than ever before.

It is a modern, cross-platform, and open-source library that supports Chrome, Safari, Firefox, WebKit, and Microsoft Edge browsers. So, you can write the tests once and then run them in multiple browsers.

With Playwright, developers can easily write tests that will detect problems and enable them to fix them quickly.

It allows automating a wide range of scenarios across diverse browsers with a single API. Hence, it provides reliable and fast execution of cross-browser testing.

This framework is built to deliver parallelized and quick automation in local and cloud environments. Among those, a cloud-based platform like LambdaTest allows running Playwright cross browser testing across 40+ real browsers and OS.

Features of Playwright

Playwright is designed to help web developers and testers to create, maintain, and run automated tests with ease.

It enables you to write code that can automate any web application with speed and accuracy. The framework is built on the same architecture as the Puppeteer and provides the same API for automation.

Playwright provides a wide range of features that make it easier for web developers and testers to automate their web testing.

Here are a few key features of a Playwright:

Rather than fiddling with code in test scripts to handle delays, Playwright carries out various verifications on elements before executing certain tasks. This makes tests more reliable and easier to maintain.
Testing scripts can modify the circumstances for the application being tested by simulating file uploads and downloads, using various authentication techniques, intercepting network requests, and substituting request responses.
Browser contexts enable testers to replicate multi-page sessions, so you can make sure all your pages can handle anonymized browsing. This is a great way to ensure persistent sessions between tabs.
Certain permissions, such as notifications and geolocation, are usually enabled and simulated; users also have the option to alter certain settings, like switching to dark mode or printing.
Presently, Playwright supports Firefox, Chromium, and Web Toolkit (Safari).
Integrating CI/CD is just like any other testing framework; it runs without any hiccups and everything runs as expected.
Provides multi-language support. You can use the Playwright API in JavaScript, Python, TypeScript,.NET, and Java.

What is the need For Cross Browser Testing using Playwright?

Cross-browser testing has become an essential part of the web development process, due to the number of different web browsers available to users.

Every web browser has its own unique features and capabilities, which can affect the way a website looks and functions.

As such, it is important that web developers ensure that their websites are tested across all major browsers to ensure compatibility.

In recent years, the emergence of Playwright has made cross-browser testing easier and more efficient.

Playwright is a framework for automation testing that works across all major browsers, making it a valuable tool for web developers.

Playwright is a modern, open-source automation library for testing web applications across different types of browsers.

It helps automate the testing of web applications in multiple browsers, ensuring that software is cross-browser compatible and functions properly across different browsers.

Steps To Execute Cross-Browser Testing Using Playwright

1. Install Playwright

To execute cross-browser testing, the first step is to install Playwright. It is a Node.js library that enables automated testing of web applications across different browsers.

It can be easily installed using NPM, using the command “npm install –save-dev @playwright/test”.

2. Write the Test Script

After installing Playwright, the next step is to write the test script. The script should be written in a language supported by Playwright, such as JavaScript, TypeScript, or Python.

The script should include the specific steps to test the web app across all browsers.

3. Execute the Test Script

Once the test script is written, it can be executed using Playwright. It can be done by running the commands in the terminal or by running the script directly.

For example, if you have a test script written in Python, you can use the command “playwright run my_python_script.py”.

You can also use the command “playwright launch my_python_script.py” to launch the browser with the specified test script.

The Playwright allows the test script to be executed in multiple browsers concurrently. This makes cross-browser testing simpler and more efficient.

4. Configure the test environment

Configure your test environment by specifying the desired browsers in the playwright.config.js file. This allows you to customize the testing parameters, such as browser selection, timeout, and other options.

5. Run your tests

Now, you can initiate your tests by executing the test script you created earlier. You can run your tests on multiple browsers in parallel.

You can also use a cloud provider to run cross-browser tests on a variety of operating systems and devices.

Playwright also supports headless execution, so you can run tests without actually launching the browser. After the tests have run, the results can be accessed for further analysis.

6. Analyze the results

After the tests are completed, the test results can be analyzed to identify issues that may have not been caught in the manual testing.

This can help detect inconsistencies in how the application performs in different browsers.

It can also help identify potential compatibility issues that should be addressed before the application is released.

Furthermore, the test results can also be used to compare performance across different browsers, allowing developers to make improvements to their applications to ensure the best possible user experience.

Best Practice of Playwright Cross-Browser Testing

Considering cross-browser testing using Playwright, it is crucial to follow best practices for the seamless working of web applications on diverse browsers. Some of those are explained below:

It is crucial to conduct cross-browser testing in multiple browsers like Firefox, Safari, Chrome, and others. Each of those has its respective rendering engine and performs differently.
You can use headless mode to run tests with Playwright. It will allow the browser to run without GUI. In addition, it provides good speed for testing and lowering resource usage.
Playwright offers certain waitFor* methods to allow waiting for specific events. Some of those methods include waitForSelector, waitForNavigation, and waitForTimeout. With the use of such methods, you will be able to write reliable tests with less probability of getting failed due to timing issues.
You can use multiple browser contexts created with Playwright. It helps to isolate your test and eliminate any interference between them.
Using the feature of taking screenshots with Playwright for visual validation. Captured screenshots at diverse stages of testing for visual validation help ensure that your software application looks alike across different browsers.
With Playwright you can retry the failed test cases a certain number of times before ending or giving up on the test. Further, it can be helpful in running the test on a slow or unstable network.
Using cloud testing services can be one of the best practices. For example, in case you do not have access to all browsers to test on, using a cloud testing platform like LambdaTest can be helpful for cross browser testing. You can run your test on multiple devices and browsers. Here is what makes the use of Playwright for cross-browser testing with LambdaTest easy.
- LambdaTest’s real device cloud gives access to over 3000 real browsers and devices for on-demand testing.
- It eases Playwright debugging with logs, video recording, and test reporting features.
- Allows secure tests of websites hosted on local machines and staging environments.

Conclusion

Playwright offers a unique combination of features that make it an incredibly versatile framework for cross-browser testing. It provides multiple language support which gives it more weightage when compared with Puppeteer and Cypress.

Thanks to its ease of use, even those with little experience will find it easy to learn and get up and running quickly. Additionally, the time it takes to build a large suite of tests is considerably lower than with other frameworks.

Hope this blog helps you, and may Playwright be at the top of your automation frameworks to use in the future.

US: A Judge Mandates that Google Allow Competing App Stores to Access Android

Published

(VOR News) – The ruling is that Google, the greatest technology firm in the world, is required to make its Android smartphone operating system available to merchants that supply applications that are in direct rivalry with Google’s. This decision was reached by a judge in the United States of America.

The Android Play store, which is owned and operated by Google, was found to be an example of an illegal monopoly arrangement by a jury in the state of California on Monday. The finding was reached by a jury. Monday is the day that this decision was come to.

An earlier federal judge ruled Google’s search engine illegal.

This finding, which came after that decision, has forced the company to suffer yet another setback. As a result of the corporation having already encountered its initial obstacle, this decision has been established. This particular decision was made by the judge during the month of August, when the month was in progress.

In light of the fact that the decision was made, what exactly does it mean that the choice was accepted?

In accordance with the verdict, Google is obligated to make it possible for users to download Android app stores that are offered by third-party competitors. For a period of three years, the corporation is prohibited from imposing restrictions on the usage of payment mechanisms that are integrated into the application.

In addition, it is important to keep in mind that Google does not possess the right to impose restrictions on the utilization of ways to make payments online.

Additionally, the verdict makes it unlawful for Google to give money to manufacturers of smartphones in order to preinstall its app store. Smartphone manufacturers are prohibited from doing so.

Furthermore, it prevents Google from the possibility of sharing the revenue that is generated by the Play store with other companies that are in the industry of delivering mobile applications.

In addition to this, the court has mandated the establishment of a technical committee that will be made up of three different people chosen at random.

The committee will be responsible for monitoring the implementation of the reforms and finding solutions to any disagreements that may occur as a consequence of the implementation of the reforms while they are being implemented. This task will fall under the committee’s purview so that it may fulfill its duties.

However, certain components were allowed to be put into action until July 1st, despite the fact that the judge’s statement suggested that the ruling would take effect on November 1st. The statement was the basis for the ruling, which ultimately became effective.

Particularly, I wanted to know what Google’s reaction would be.

There is a fact that Google does not adhere to this directive, which has been brought to their attention. This document argued that the alterations that the judge had ordered to be made would “cause a range of unintended consequences that will harm American consumers, developers, and device makers.”

The judge had ordered the modifications to be implemented. The alterations were to be carried out as indicated by the judge’s ruling. The judge made it clear that he expected these revisions to be carried out in accordance with his guidance.

The company’s regulatory affairs vice president, Lee-Anne Mulholland, provided the following statement: “We look forward to continuing to make our case on appeal, and we will continue to advocate for what is best for developers, device manufacturers, and the billions of Android users around the world.”

On average, over seventy percent of the total market for smartphones and other mobile devices is comprised of mobile devices that are powered by the Android operating system. Both smartphones and other small mobile devices are included in this category.

In the event that the Play app store continues to be shown on the home page and that other Google applications are pre-installed prior to the installation of the Android application, smartphone manufacturers are entitled to install the Android application at no cost at their discretion.

Additionally, the Android application can be installed on devices that are manufactured for smartphones.

WhatsApp Now Features a “Mention” Tool for Status Updates and Stories.

Published

(VOR News) – Those who use WhatsApp now have the ability to mention other people in their stories or status updates as a consequence of a feature that was only recently enabled on the platform.

Previous to this point, this capability was not available. It wasn’t until quite recently that this capability became available to the public.

According to the information that was provided by the company, users now have the opportunity to tag close friends in their stories, and the person who is mentioned will have the option to go back and re-share an earlier version of that story. This information was provided by the company. The corporation was kind enough to reveal this information to us.

Because of a new feature that has been added to the WhatsApp app, users now have the opportunity to like individual stories and status updates.

This capability was previously unavailable to WhatsApp users.

A significant amount of progress has been made in this context. Alternative readers now have the chance to “like” a work, which is comparable to liking a post on Facebook. This feature was introduced in recent years. When compared to the past, this is a tremendous shift.

At one point in time, viewers were only permitted to observe the total number of views that a particular story had gotten. These restrictions were eliminated in later versions of the software.

Additionally, it is essential that the likes and reactions to a story be kept anonymous during the entire process. One of the factors that contributes to the general mystery that surrounds this characteristic is the fact that this is one of the elements.

The person who brought it to the attention of others is the only person who will be able to judge who enjoyed it and who did not care about it. These individuals will be able to make this determination.

A notification will be issued to the individual who was referenced earlier in the sentence and who was named in the story or status update that was discussed. A notification of this nature will be sent to the individual via WhatsApp.

This message will be sent to the user in question whenever that person makes a reference to another person while they are in the process of elaborating on a narrative or updating their status. You will receive a notification alerting you that you have been tagged in the narrative.

This notification will be delivered to the person who receives this message. In addition, students will be provided with the opportunity to re-share the tale for themselves.

It is important to note that if the names of individuals who have been referenced in a narrative or a status update are included in any of these, then the names of those individuals will not be accessible to any third party through any of these. In light of the fact that the identities of those individuals will be concealed from public disclosure, this is the condition that will be required.

While WhatsApp recently made the announcement that it will be incorporating this functionality, it is highly likely that not all users will have access to it at the same time.

This is despite the fact that WhatsApp recently made this announcement.

Despite the fact that WhatsApp has only recently made a public announcement that it will move forward with the deployment, this is the situation that has presented itself.

As soon as a short period of time has elapsed, access will be made available to each and every person on the entire world.

Additionally, WhatsApp has hinted that new functionalities might be introduced to the status and updates tab in the future months.

The purpose of these capabilities is to provide users with assistance in maintaining healthy connections with the individuals who play a vital role in their living experiences. This is done in order to give users with support in maintaining close relationships with the folks who are the subject of the inquiry.

It is with the purpose of supporting users in successfully keeping close ties with the individuals in question that this step is taken.

Over The Planned “Link Tax” Bill, Google Threatens to Remove NZ News Links.

Published

4 months ago

October 4, 2024

Salman

(VOR News) – Google has sent a strong message to the New Zealand government, threatening to stop boosting local news content should the Fair Digital News Bargaining Bill become law.

The law, put up by the Labour government and backed by the coalition in power at the moment, mandates that digital companies such as Google pay back news organizations for links to their material.

News publishers, on the other hand, charge the tech giant with “corporate bullying.”

Google says this measure may have unanticipated effects.

Google New Zealand’s country director, Caroline Rainsford, voiced her worries that the law, which is being referred to as a “link tax,” is not doing enough to support the media industry in New Zealand right now.

She underlined that Google would have to make major adjustments if the previously mentioned law were to pass, including cutting off links to news articles from its Search, News, and Discover platforms and cutting off financial ties with regional publications.

According to Rainsford, similar legislation has been proposed and approved in other nations including Australia and Canada, but it has not been proven to be effective there and breaches the principles of the open web.

She drew attention to the fact that smaller media outlets will be most negatively impacted, which will limit their capacity to reach prospective audiences.

Google says its alternative options will protect smaller, local media from negative effects.

Conversely, it conveys apprehension regarding the possible fiscal obligations and vagueness of the legislation, which it feels generates an intolerable level of ambiguity for enterprises functioning within New Zealand.

The New Zealand News Publishers Association (NPA) has reacted to Google’s warnings by alleging that the internet behemoth is using coercive tactics.

They specifically contend that the need for regulation stems from the market distortion that Google and other tech giants have created, which has fueled their expansion into some of the most significant corporations in global history.

The legislation aims to create a more equal framework that media businesses can use to negotiate commercial relationships with technological platforms that profit from their content.

New Zealand Media Editors CEO Michael Boggs stated that he was in favor of the bill, citing the fact that Google now makes a substantial profit from material created by regional publications.

He also emphasized that the use of artificial intelligence by Google—which frequently makes references to news articles without giving credit to the original sources—highlights the significance of enacting legislation.

Paul Goldsmith, the Minister of Media and Communications, has stated that the government is now evaluating various viewpoints and is still in the consultation phase.

He stated that the government and Google have been having continuous talks and will keep up these ongoing discussions.

However, not all political parties accept the validity of the Act.

The ACT Party’s leader, David Seymour, has voiced his displeasure of the proposal, saying that Google is a game the government is “playing chicken” with. He threatened the smaller media companies, saying that they would suffer from worse search engine rankings if the internet giant followed through on its promises.

Seymour contended that it is not the government’s responsibility to shield companies from shifts in the market brought about by consumer preferences.

The things that have happened in other nations are similar to what has happened in New Zealand.

Google has agreements with a number of Australian media firms that are in compliance with its News Media Bargaining Code. These agreements contain provisions that permit an annual cancellation of these agreements.

Due to the government’s decision to exempt Google from the Online News Act, the company has committed to supporting news dissemination by contributing annually to the Canadian journalistic community.

The New Zealand measure is consistent with global approaches aimed at regulating the relationships that exist between technology corporations and media organizations.

It’s hard to say what will happen with the Fair Digital News Bargaining Bill as the discussion goes on. Google and the New Zealand media landscape are preparing for what might be a protracted legal battle.
