Automating Acceptance Tests For Mobile Apps

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.

What is Cognitive Overhead in Design and How to Reduce it?

Taking in more information than what we can process slows us down. Be it a computer or human, no one can process beyond a specified level. If you open hundreds of apps in a computer, at same point of time it will stop working, slow down, or even crash. Same is with humans, every human has a defined cognitive load that the memory can process. Making anyone process more information than defined will result in cognitive overloading.

Top 10 Books Every Tester Should Read

While recently cleaning out my bookshelf, I dusted off my old copy of Testing Computer Software written by Cem Kaner, Hung Q Nguyen, and Jack Falk. I was given this book back in 2003 by my first computer science teacher as a present for a project well done. This brought back some memories and got me thinking how much books affect our lives even in this modern blog and youtube age. There are courses for everything, tutorials for everything, and a blog about it somewhere on medium. However nothing compares to a hardcore information download you can get from a well written book by truly legendary experts of a field.
