A Complete Guide To CSS Container Queries

In 2007, Steve Jobs launched the first iPhone, which revolutionized the world. But because of that, many businesses dealt with the problem of changing the layout of websites from desktop to mobile by delivering completely different mobile-compatible websites under the subdomain of ‘m’ (e.g., https://m.facebook.com). And we were all trying to figure out how to work in this new world of contending with mobile and desktop screen sizes.

How To Use driver.FindElement And driver.FindElements In Selenium C#

One of the essential parts when performing automated UI testing, whether using Selenium or another framework, is identifying the correct web elements the tests will interact with. However, if the web elements are not located correctly, you might get NoSuchElementException in Selenium. This would cause a false negative result because we won’t get to the actual functionality check. Instead, our test will fail simply because it failed to interact with the correct element.

How To Refresh Page Using Selenium C# [Complete Tutorial]

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.

Testing in Production: A Detailed Guide

When most firms employed a waterfall development model, it was widely joked about in the industry that Google kept its products in beta forever. Google has been a pioneer in making the case for in-production testing. Traditionally, before a build could go live, a tester was responsible for testing all scenarios, both defined and extempore, in a testing environment. However, this concept is evolving on multiple fronts today. For example, the tester is no longer testing alone. Developers, designers, build engineers, other stakeholders, and end users, both inside and outside the product team, are testing the product and providing feedback.

Different Ways To Style CSS Box Shadow Effects

Have you ever visited a website that only has plain text and images? Most probably, no. It’s because such websites do not exist now. But there was a time when websites only had plain text and images with almost no styling. For the longest time, websites did not focus on user experience. For instance, this is how eBay’s homepage looked in 1999.
