How To Get Started With Cypress Debugging

One of the most important tasks of a software developer is not just writing code fast; it is the ability to find what causes errors and bugs whenever you encounter one and the ability to solve them quickly.

A Reconsideration of Software Testing Metrics

There is just one area where each member of the software testing community has a distinct point of view! Metrics! This contentious issue sparks intense disputes, and most conversations finish with no definitive conclusion. It covers a wide range of topics: How can testing efforts be measured? What is the most effective technique to assess effectiveness? Which of the many components should be quantified? How can we measure the quality of our testing performance, among other things?
