内容紹介

In recent years, software development costs have increased, and the debugging costs, which account for half of software development costs, have also increased accordingly. Then, many debugging techniques have been proposed to reduce debugging costs. In this lecture, I introduce typical debugging techniques and our proposed debugging technique. We proposed Near-Omniscient Debugging which monitored a Java program's execution within limited storage space. We confirmed the usefulness of Near-Omniscient Debugging by measuring the data dependencies' accuracy of the execution traces, the amount of execution traces, and the percentage of bugs whose bug-related instructions were completely recorded. Using this debugging method, we have implemented a tool named NOD4J which annotates the source code with observed values in an HTML format. We show two examples that our tool can debug defects using incomplete execution traces.
