Code Comprehension task (Java Developers)

We are a research group at Polytechnique de Montreal and we are performing an empirical study on software anti-patterns and design quality. Your task consists of answering some comprehension questions about two open-source systems. The questions are grouped in three categories: (1) finding a focus point in some subset of classes and interfaces of some code fragments relevant to a comprehension task; (2) focusing on a particular class believed to be related to some task or classes; (3) understanding a set of classes and their relations between different code fragments. In each category you have to answer only two questions using a web surveying system. To answer the questions, you should open the source code (indicated in each system’s task) in Eclipse. We ask you to record your exploration activities using a google chrome extension. After finalizing the two comprehension task, we ask you to fill a survey about 5 diff files (patches) from open source systems and your job consist in identifying if they were generated by developer or by software, and to rank them according to their quality. Thanks for participating in our study!
