Bug Magnet: A Free Exploratory Testing Tool

Bug Magnet: A Free Exploratory Testing Tool

I want to quickly share with you a cool little Chrome extension named Bug Magnet that will help you automate some data validation input scenarios that are commonly known to cause issues.

Once you have Bug Magnet installed, you can right click on any field in a Chrome or FireFox browser and choose some of the most common problematic values and edge cases from its Menu option.

This is awesome because it will save you a bunch of time as well as remind you of some of the more common data input issues that are sure to find bugs in your application.

Bug Magnet is also open-source and customizable, so you can download and modify the source code from its GitHub location. For Firefox implementation check out Brian D Goad’s GitHub project.

Install Bug Magnet

Let’s take a quick look at Bug Magnet in action:


  • Click on the FREE button
  • Click on the Add button from the Confirm New Extension popup


Cool! Once it’s installed, let’s explore some of its options:

Bug Magnet Menu Options

  • Navigate to http://www.orbitz.com/
  • Right click on the Check-In field and select the Bug Magnet menu option
  • Currently there are seven main options:
  • Lorems – allows you to add filler text in Latin, Cyrillic, Arabic, Chinese and Mixed charsets
  • Text size – allows you to add text strings that are certain lengths, with and without spaces
  • Names – Different name options like O’Grady, NULL and other tricky names
  • E-mail addresses – Valid and Invalid examples, like missing @ and 2 @@
  • Numbers – Different boundary number options like 0, -1
  • Whitespace – Tabs and Newline and Leading spaces
  • Format exploits like SQL injection and HTML parsing


Exploratory Testing Buddy

In my opinion, this is a great little tool to help you with exploratory testing, and is a great reminder of the type of problem user-input issues you should be trying against your application.

Using Bug Magnet when doing exploratory testing should help uncover issues with your application like error handling, boundary-related errors, and security issues.

Also, if you have ever found yourself doing exploratory testing and wondering what values you should try when testing, say, a text box that should only allow integer values, Bug Magnet is helpful in that it gives you an idea of some standard problematic values to start with.

Even if your application doesn’t work in Chrome or is a thick client application, you can use this as a kind of checklist of things to try when performing your exploratory testing.
