Delta Debugging

Delta Debugging automates the scientific method of debugging. The Delta Debugging algorithm isolates failure causes automatically - by systematically narrowing down failure-inducing circumstances until a minimal set remains. Delta Debugging has been applied to isolate failure-inducing program input (e.g. an HTML page that makes a Web browser fail), failure-inducing user interaction (e.g. the keystrokes that make a program crash), or failure-inducing changes to the program code (e.g. after a failing regression test).
