DB4: Statistical Debugging

SUMMARY OF CONTENT:

The fourth chapter of the book “Debugging Book” describes how statistics during debugging work. The premise of the chapter is that there is a statistical correlation between specific events during coding and failures.

By collecting events from tests, exceptions can be analyzed which can be used to indicate failure. These events can be visualized on a table for statistical analysis, thus furthering connections between statistical error and connected events. This information can be collected with a tool called Collector, which works by recording events based on when they occur. After these events are recorded and organized onto a table, the statistical connections can be made.

PERSONAL REFLECTION:

This chapter introduces us to the idea of statistical debugging, and explains how statistics and errors can be traced to have their connections found.

RELEVANT ACTION ITEMS:

Utilizing statistics, we can determine when errors may be made in development for our Chasten and Conveyor tools ahead of time.
