What Is Exploratory Testing?
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.
For example, developers of a shopping website know what it is meant to do. Let users select products of their choice, move it to cart, pay and confirm their order. Exploratory testing helps verify that the system is working as expected, but also that it is an easy and pleasant process for users.
