FuzzWinForms

Random UI Fuzzer (Monkey-Fuzzer) for finding bugs in Windows Forms

Features:

Random input of x number of actions using User32 API

Each input has a configurable chance of occurring

• Mouse click events
  • Left click
  • Right click
  • Middle Click
  • Click and Drag
• Keyboard events
  • Most keys on keyboard with chance of modifiers being active (SHIFT/CTRL/ALT)
  • A dictionary of 'evil' strings which it may use

Action recording and replay functionality

Replay minimizer based on Lithium (most replays go down to <10 actions)

Application Event log capture with filters

Interruption detection, so it doesn't take control over your session

Pre/Post-Test actions, so you can (restore databases/config files/etc to) ensure a consistent test

Distance comparison on errors, so the minimizer will work if the error doesnt match 100%

Warning: This tool has no idea what it is doing - and does a lot - so use it at your own risk, preferably in a snapshotted VM with no network connectivity.

TO DO:

• Add a log file reader class and add it to data collected during the test
• Add a db of previously seen error
• Further automate the workflow
• Add email option to raise errors in support system
