Bug Magnet is an exploratory testing assistant for Chrome developed by Gojko Adzic. This free add-on provides convenient access to common boundaries and edge cases for exploratory testing. With Bug Magnet, you can easily add problematic values and edge cases to the right-click context menu of editable elements, making them readily accessible during testing sessions.

One of the key features of Bug Magnet is its ability to extend easily with your own config files. This allows you to customize the values and edge cases that are available in the context menu, making it even more tailored to your specific testing needs. Bug Magnet works on input fields, text areas, and content editable DIVs, providing a wide range of options for testing different types of elements.

Bug Magnet is designed to have a minimal impact on your web app execution. With a tiny overhead of less than 1k per page and no 3rd party library dependencies, it runs completely passively in the background, ensuring that it does not interfere with your testing process. It also works on multi-frame pages, as long as they are from the same domain.

Bug Magnet is a valuable tool for exploratory testing in Chrome, offering quick access to common problematic values and edge cases. Its flexibility, ease of use, and customizability make it a must-have for testers looking to enhance their testing capabilities.
