13 Best Java Testing Frameworks For 2023

The fact is not alien to us anymore that cross browser testing is imperative to enhance your application’s user experience. Enhanced knowledge of popular and highly acclaimed testing frameworks goes a long way in developing a new app. It holds more significance if you are a full-stack developer or expert programmer.

11 Best CSS Grid Layout Generators

HTML5, CSS, and JavaScript are the three most popular languages for building a website. Earlier, developers would have to learn programming before explicitly creating responsive web design. However, with the recent trends in web development, things have gotten a lot easier with tools that can help you build the website of your dreams with zero code knowledge (although knowing how to code does not hurt)! One of those tools is a CSS grid layout generator. It creates responsive grids that you can later incorporate into a website for the design layout.

Gauge Framework – How to Perform Test Automation

Gauge is a free open source test automation framework released by creators of Selenium, ThoughtWorks. Test automation with Gauge framework is used to create readable and maintainable tests with languages of your choice. Users who are looking for integrating continuous testing pipeline into their CI-CD(Continuous Integration and Continuous Delivery) process for supporting faster release cycles. Gauge framework is gaining the popularity as a great test automation framework for performing cross browser testing.

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.

Need for Build Automation Tools for Selenium Automation Testing

Being an automation tester, we do realize that in a release cycle, time is always of the essence.! Selenium test automation helps to save us a considerable amount of time in our test cycles. However, it is pivotal to note the way through which you are executing your Selenium testing scripts. Which frameworks are you using? Are you doing it with an in-house infrastructure or with an online Selenium Grid? Are you making use of build automation tools or not?!
