In general, software testers have a challenging job. Software testing is frequently the final significant activity undertaken prior to actually delivering a product. Since the terms “software” and “late” are nearly synonymous, it is the testers that frequently catch the ire of the whole business as they try to test the software at the end. It is the testers who are under pressure to finish faster and deem the product “release candidate” before they have had enough opportunity to be comfortable. To make matters worse, if bugs are discovered in the product after it has been released, everyone looks to the testers and says, “Why didn’t you spot those bugs?” The testers did not cause the bugs, but they must bear some of the guilt for the bugs that were disclosed.
In addition to the four values, the Agile Manifesto contains twelve principles that are used as guides for all methodologies included under the Agile movement, such as XP, Scrum, and Kanban.
While there is a huge demand and need to run Selenium Test Automation, the experts always suggest not to automate every possible test. Exhaustive Testing is not possible, and Automating everything is not sustainable.
Coaching is a term that is now being mentioned a lot more in the leadership space. Having grown successful teams I thought that I was well acquainted with this subject.
