Agile software development stems from a philosophy that being agile means creating and responding to change swiftly. Agile means having the ability to adapt and respond to change without dissolving into chaos. Being Agile involves teamwork built on diverse capabilities, skills, and talents. Team members include both the business and software development sides working together to produce working software that meets or exceeds customer expectations continuously.
When working on web automation with Selenium, I encountered scenarios where I needed to refresh pages from time to time. When does this happen? One scenario is that I needed to refresh the page to check that the data I expected to see was still available even after refreshing. Another possibility is to clear form data without going through each input individually.
Building a website is all about keeping the user experience in mind. Ultimately, it’s about providing visitors with a mind-blowing experience so they’ll keep coming back. One way to ensure visitors have a great time on your site is to add some eye-catching text or image animations.
Automating testing is a crucial step in the development pipeline of a software product. In an agile development environment, where there is continuous development, deployment, and maintenance of software products, automation testing ensures that the end software products delivered are error-free.
As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers. Even if it is supported, the feature might be experimental and not work consistently across all browsers. Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????
