ChatGPT broke all Internet records by going viral in the first week of its launch. A million users in 5 days are unprecedented. A conversational AI that can answer natural language-based questions and create poems, write movie scripts, write social media posts, write descriptive essays, and do tons of amazing things. Our first thought when we got access to the platform was how to use this amazing platform to make the lives of web and mobile app testers easier. And most importantly, how we can use ChatGPT for automated testing.
Agile has unquestionable benefits. The mainstream method has assisted numerous businesses in increasing organizational flexibility as a result, developing better, more intuitive software. Distributed development is also an important strategy for software companies. It gives access to global talent, the use of offshore outsourcing to reduce operating costs, and round-the-clock development.
People love to watch, read and interact with quality content — especially video content. Whether it is sports, news, TV shows, or videos captured on smartphones, people crave digital content. The emergence of OTT platforms has already shaped the way people consume content. Viewers can now enjoy their favorite shows whenever they want rather than at pre-set times. Thus, the OTT platform’s concept of viewing anything, anytime, anywhere has hit the right chord.
Sometimes, in our test code, we need to handle actions that apparently could not be done automatically. For example, some mouse actions such as context click, double click, drag and drop, mouse movements, and some special key down and key up actions. These specific actions could be crucial depending on the project context.
How do we acquire knowledge? This is one of the seemingly basic but critical questions you and your team members must ask and consider. We are experts; therefore, we understand why we study and what we should learn. However, many of us do not give enough thought to how we learn.
