Using ChatGPT for Test Automation

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.

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.

13 Best Test Automation Frameworks: The 2021 List

Automation frameworks enable automation testers by simplifying the test development and execution activities. A typical automation framework provides an environment for executing test plans and generating repeatable output. They are specialized tools that assist you in your everyday test automation tasks. Whether it is a test runner, an action recording tool, or a web testing tool, it is there to remove all the hard work from building test scripts and leave you with more time to do quality checks. Test Automation is a proven, cost-effective approach to improving software development. Therefore, choosing the best test automation framework can prove crucial to your test results and QA timeframes.
