Two-phase Model-based Testing

Most test automation tools just do test execution automation. Without test design involved in the whole test automation process, the test cases remain ad hoc and detect only simple bugs. This solution is just automation without real testing. In addition, test execution automation is very inefficient.

Putting Together a Testing Team

As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.

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.

How To Run Cypress Tests In Azure DevOps Pipeline

When software developers took years to create and introduce new products to the market is long gone. Users (or consumers) today are more eager to use their favorite applications with the latest bells and whistles. However, users today don’t have the patience to work around bugs, errors, and design flaws. People have less self-control, and if your product or application doesn’t make life easier for users, they’ll leave for a better solution.
