The web paradigm has changed considerably over the last few years. Web 2.0, a term coined way back in 1999, was one of the pivotal moments in the history of the Internet. UGC (User Generated Content), ease of use, and interoperability for the end-users were the key pillars of Web 2.0. Consumers who were only consuming content up till now started creating different forms of content (e.g., text, audio, video, etc.).
Howdy testers! June has ended, and it’s time to give you a refresher on everything that happened at LambdaTest over the last month. We are thrilled to share that we are live with Cypress testing and that our very own LT Browser is free for all LambdaTest users. That’s not all, folks! We have also added a whole new range of browsers, devices & features to make testing more effortless than ever.
Have you ever struggled with handling hidden elements while automating a web or mobile application? I was recently automating an eCommerce application. I struggled with handling hidden elements on the web page.
I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives.There is also a lot of discussion about “agile”, much written about “agile”, and there are many presentations about “agile”. A question that is often asked is what comes after “agile”? Many testers work in “agile” teams so this question matters to us.
Are members of agile teams different from members of other teams? Both yes and no. Yes, because some of the behaviors we observe in agile teams are more distinct than in non-agile teams. And no, because we are talking about individuals!
