27 Best Website Testing Tools In 2022

Testing is a critical step in any web application development process. However, it can be an overwhelming task if you don’t have the right tools and expertise. A large percentage of websites still launch with errors that frustrate users and negatively affect the overall success of the site. When a website faces failure after launch, it costs time and money to fix.

Your Favorite Dev Browser Has Evolved! The All New LT Browser 2.0

We launched LT Browser in 2020, and we were overwhelmed by the response as it was awarded as the #5 product of the day on the ProductHunt platform. Today, after 74,585 downloads and 7,000 total test runs with an average of 100 test runs each day, the LT Browser has continued to help developers build responsive web designs in a jiffy.

Difference Between Web And Mobile Application Testing

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 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.
