Visual programming languages employ visual representation to make programming easier and make programs more reliable and more accessible. Visual program testing becomes increasingly important as more and more visual programming languages and visual programming environments come into real use. In this work, we focus on one important class of visual...
Like other scientific fields, computer science is in great need of experimentation to support, improve, disprove and even establish theories. One area in which experimental results are highly desired involves regression testing, which is performed on modified software to provide confidence that the software behaves correctly and that modifications have...
Visualization is a useful method to teach classes in algorithms and data structures. Many animation systems of algorithms and data structures have been implemented. In these systems, students can set initial conditions, run algorithms and view the result graphically. In this project, a small visualization tool library is implemented using...
Prioritization techniques are used to schedule test cases to execute in a specific order to maximize some objective function. There are a variety of possible objective functions, such as a function that measures how quickly faults can be detected within the testing process, or a function that measures how fast...
The project aims at building an application that would simulate a transparency that can either be overlaid on top of the graphical display of another application or used as a stand-alone by accepting input from a keyboard or a mouse to enhance a presentation. The project provides an environment to...
Software maintenance is an expensive part of the software lifecycle: estimates put its cost at up to two-thirds of the entire cost of software. Regression testing, which tests software after it has been modified to help assess and increase its reliability, is responsible for a large part of this cost....
Forms are an easy-to-use interface to access a database, including a remote database on the Internet. An entity-relationship (ER} diagram, which is a pictorial representation of a database schema, is widely used in designing a database. A class diagram, which shows set of classes, relationships among them, and associations, are...
Test case generation in software testing is a process of developing a set of test data that satisfies a particular test adequacy criterion. It is desirable to automate this process since doing it manually is not only technically difficult but also tedious and time-consuming. Although there has been considerable research...
Researchers have hypothesized that if we could estimate the probability that a fault in a code component will a cause a failure, we could use this estimate to improve the fault-detection effectiveness of code-coverage-based testing. If this hypothesis could be supported, it would motivate further research in this area and...
Graphics resource allocation has often existed on the periphery of graphics research, taking second place to faster or more realistic algorithms for global illumination and modeling. Most research has focused on generating sets of images that best match the effects one might see in photographs. While this approach works well...
