Intense competition in the mobile apps market means it is important to maintain high levels
of app reliability to avoid losing users. Yet despite its importance, app reliability is …

Context: Developers tend to search and reuse code snippets from a large-scale codebase
when they want to implement some functions that exist in the previous projects, which can …

Abstract “App stores” are online software stores where end users may browse, purchase,

To help programmers find proper API methods and learn API usages, researchers have
proposed various code search engines. Given an API of interest, a code search engine can …

Programs often emit natural language messages, eg, in logging statements or exceptions
raised on unexpected paths. To be meaningful to users and developers, the message, ie …

Modern software systems are commonly built on top of frameworks. To accelerate the
learning process of features provided by frameworks, code samples are made available to …

Although the exception handling mechanism is critical for resolving runtime errors, bugs
inside this process can have far-reaching impacts. Therefore, researchers have proposed …

Exceptions often signal faulty or undesired behavior; hence, high-quality test suites should
also target exceptional behavior. This paper is a large-scale study of exceptional tests-which …

Runtime Exceptions (REs) are an important class of bugs that occur frequently during code
development. Traditional Automatic Program Repair (APR) tools are of limited use in this “in …

Developers build on Application Programming Interfaces (APIs) to reuse existing
functionalities of code libraries. Despite the benefits of reusing established libraries (eg, time …
