Webinar: Move Forward With An Effective Test Automation Strategy [Voices of Community]

The key to successful test automation is to focus on tasks that maximize the return on investment (ROI), ensuring that you are automating the right tests and automating them in the right way. This is where test automation strategies come into play.

Website Testing: A Detailed Guide

Websites and web apps are growing in number day by day, and so are the expectations of people for a pleasant web experience. Even though the World Wide Web (WWW) was invented only in 1989 (32 years back), this technology has revolutionized the world we know back then. The best part is that it has made life easier for us. You no longer have to stand in long queues to pay your bills. You can get that done within a few minutes by visiting their website, web app, or mobile app.

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.
