From October 2016 to November 2017, Android released 4 major versions and iOS released 9 major updates. Its very good for users but it is problematic for developers and absolute hell for testers. One such problem testers face because of fast release cycles is Acceptance Testing.
Recently, we started digging into Reddit and there we found out many threads which are very useful for testers. While I was going through some of the links, I found this Reddit thread which was talking about tools for the testers and I found it pretty interesting. So, we decided to make a list for you by compiling all the utility tools for the testers.
The human body is a combination of different systems most of which are independent yet, working together as one. Each system has a specific functionality of its own. All the organs with a multitude of other supporting frameworks form a fully functioning body. Now, if applied to software systems, this is the concept of a microservice architecture.
The quickest hack to build a live web design fast is to follow app design trends already set up by hugely popular SaaS companies. So before you kick-start the designing and development phase of your web app, check out some of the best SaaS design inspiration that has already helped companies succeed. But where to find those inspirations??
Browser compatibility testing is a complex problem. From chrome’s latest version 69 to the oldest one, from Firefox’s latest version 61 to the oldest one there are approximately 130 browser versions. This is just the case for two browsers, if I include every browser and browser version, they’ll add up to to hundreds of browser versions. And if I check for their combinations with different windows and mac operating system it will add up to thousands. I have still not completed ????
