I was emailing a service about their documentation and while their doc was good, about one particularly tricky concept they told me that once you use it for a while, that’s when you’ll understand it. In other words: you’ll only understand it after you understand it. I didn’t like that response. I want documentation that takes me from an unproductive newbie to a somewhat functioning journeyperson.

In exploratory testing, testers check a system without a plan in mind to discover bugs that users may face when navigating a website or app. It tries to mimic the personal freedom and choices of individual end-users. It is a simultaneous process in which testers go through the software of their own accord to understand the quality of the user experience it provides.
