How to Position Your Team for Success in Estimation

Estimates are critical if you want to be successful with projects. If you begin with a bad estimating approach, the project will almost certainly fail. To produce a much more promising estimate, direct each estimation-process issue toward a repeatable standard process. A smart approach reduces the degree of uncertainty. When dealing with presales phases, having the most precise estimation findings can assist you to deal with the project plan. This also helps the process to function more successfully, especially when faced with tight schedules and the danger of deviation.

Hey Testers! We know it’s been tough out there at this time when the pandemic is far from gone and remote working has become the new normal. Regardless of all the hurdles, we are continually working to bring more features on-board for a seamless cross-browser testing experience.

Three Techniques for Improved Communication and Testing

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.

40 Best UI Testing Tools And Techniques

A good User Interface (UI) is essential to the quality of software or application. A well-designed, sleek, and modern UI goes a long way towards providing a high-quality product for your customers − something that will turn them on.

What is Selenium Grid & Advantages of Selenium Grid

Manual cross browser testing is neither efficient nor scalable as it will take ages to test on all permutations & combinations of browsers, operating systems, and their versions. Like every developer, I have also gone through that ‘I can do it all phase’. But if you are stuck validating your code changes over hundreds of browsers and OS combinations then your release window is going to look even shorter than it already is. This is why automated browser testing can be pivotal for modern-day release cycles as it speeds up the entire process of cross browser compatibility.
