Top 10 Java Unit Testing Frameworks for 2021

When we talk about programming in the modern tech world, Java instantly comes to our mind. After all, it is considered as one of the most versatile programming languages. Looking back on its history, Java has always had an extraordinary position in a back-end developer’s heart. A majority of developers enjoy Java due to its platform independency, security, ease of use, variety of accessible resources, and several other essential features. These traits appreciably contributed to the popularity of Java as a programming language – as of 2018, there were seven million or more Java developers globally.

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.

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.

Web Analytics Tools to Help You Understand Your Users

Whether you are a businessman, or a blogger, or you have just launched your online portal for your next venture, it’s important to know how your website is behaving across all browsers and platforms. When you put so much money for the online presence you would want to know whether that amount is getting you something or not.
