Exploratory Testing is all about exploring the software by navigating random paths and discovering what it can do and what it can’t. Planning and Test Case execution are on least priority in this type of testing as there are no pre-defined steps. In exploratory testing we try to verify how well system reacts to special/invalid inputs and edge cases.

A rich test data set including both valid and invalid inputs is required to perform exploratory testing effectively. In this article, I will share with you a super cool google chrome extension named “Bug Magnet” which will help you configure Data validations and variety input scenarios likely to cause issues.
