Part IV: Reducing Failure Causes

In this part, we show how to narrow down failures by systematic experimentation.

• Reducing Failure-Inducing Inputs introduces delta debugging, a technique to automatically reduce a failure-inducing input to a minimum.

• Isolating Failure-Inducing Changes shows how to identify changes that cause failures - manually and automatically.

• In Debugging Concurrent Programs, we show how to detect and debug concurrency issues.
