Developers often use crash reports to understand the root cause of bugs. However, locating the buggy source code snippet from such information is a challenging task, mainly when the log database contains many crash reports. To mitigate this issue, recent ...

In the computing education community, discussion is growing about the benefits of teaching programming by explicitly using notional machines to help students. To-date most work is largely theoretical and little work addresses actually using them in a ...

Context: Software development projects increasingly adopt unit testing as a way to identify and correct program faults early in the construction process. Code that is unit tested should therefore have fewer failures associated with it. Objective: ...

The term "the machine" is commonly used to refer to the complicated physical hardware running similarly complex software that ultimately executes programs. The idea that programmers write programs for a notional machine - an abstract model of an ...

Proactive security reviews and test efforts are a necessary component of the software development lifecycle. Resource limitations often preclude reviewing the entire code base. Making informed decisions on what code to review can improve a team's ...

During the evolution of a software system, a large number of bug reports are submitted. Locating the source code files that need to be fixed to resolve the bugs is a challenging problem. Thus, there is a need for a technique that can automatically ...

Security requirements around software systems have become more stringent as society becomes more interconnected via the Internet. New ways of prioritizing security efforts are needed so security professionals can use their time effectively to find ...

Proactive security review and test efforts are a necessary component of the software development lifecycle. Since resource limitations often preclude reviewing, testing and fortifying the entire code base, prioritizing what code to review/test can ...

Security testing and reviewing efforts are a necessity for software projects, but are time-consuming and expensive to apply. Identifying vulnerable code supports decision-making during all phases of software development. An approach for identifying ...

Many bug localization techniques rely on Text Retrieval (TR) models. The most successful approaches have been proven to be the ones combining TR techniques with static analysis, dynamic analysis, and/or software repositories information. Dynamic ...

Modern programs require useful and robust APIs to guarantee applications' responsiveness. Given that large APIs can be used by novice developers and that not all experts are infallible, a well-designed API should inform developers about all the possible ...

Modern programs rely on large application programming interfaces (APIs). The Android framework comprises 231 core APIs, and is used by countless developers. We examine a sample of 4,900 distinct crash stack traces from 1,800 different Android ...

Program debugging is an important process to improve the quality of software. Runtime exception can occur often and can be difficult to debug. In this paper, we present a new approach for locating faults that cause runtime exceptions in Java programs ...

In software engineering experiments, the description of bug reports is typically treated as natural language text, although it often contains stack traces, source code, and patches. Neglecting such structural elements is a loss of valuable information; ...
