Generating and maintaining REST API documentation with usage examples can be a time consuming and expensive process for evolving APIs. Most REST API documentation tools focus on automating the documentation of the API objects, but require manual effort for capturing usage examples. Consequently, REST API developers need to know the cost vs. benefit of providing usage examples in the documentation...
Block-based programming environments are typically designed for desktop machines or mobile devices. Desktops and mobiles are generally designed for single users to interact with, which makes it hard for multiple users to collaborate effectively. In this paper we explore the possibilities of digital multi-touch tabletops to foster collaborative programming in a block-based paradigm. We note both the...
Gamification of software engineering tasks improve developer engagement, but has been limited to mechanisms such as points and badges. We believe that a tool that provides developers an interface analogous to computer games can represent the gamification of software engineering tasks more effectively via software visualization. We introduce CityVR – an interactive software visualization tool that...
Many visualizations have proven to be effective in supporting various software related tasks. Although multiple media can be used to display a visualization, the standard computer screen is used the most. We hypothesize that the medium has a role in their effectiveness. We investigate our hypotheses by conducting a controlled user experiment. In the experiment we focus on the 3D city visualization...
Generating and maintaining an up-to-date API documentation is a challenging problem for evolving REST APIs. At Cisco, we've used SpyREST, an automated REST API documentation tool, via our functional tests to solve this problem with one of our APIs for a cyber security application over the past eighteen months. Using this approach, we've avoided the need for extensive manual effort by leveraging our...
Developing a usable Application Programming Interface (API) is a complex and expensive task. Two major factors play important roles on the usability of an API: the design and resources (e.g. documentation, tutorials). API Developers typically evaluate the usability of an API after implementation that results in refactoring tasks if an API lacks usability after development. This refactoring could be...
RESTful API documentation is expensive to produce and maintain due to the lack of reusable tools and automated solutions. Most RESTful APIs are documented manually and the API developers are responsible for keeping the documentation up to date as the API evolves making the process both costly and error-prone. In this paper we introduce a novel technique using an HTTP proxy server that can be used...
RESTful APIs are often manually documented. As a result, the process of maintaining the documentation of RESTful APIs is both expensive and error-prone. In this demonstration paper, we present SpyREST as an automated software as a service tool that can be used to document RESTful APIs. SpyREST leverages an HTTP Proxy server to intercept real API calls to automatically collect and generate RESTful...
Large codebases — in the order of millions of lines of code (MLOC) — are incredibly complex. Whether fixing a fault, or implementing a new feature, changes to such systems often have unanticipated effects, as it is impossible for a developer to maintain a complete understanding of the code in their head.
When applications are integrated using web APIs, changes on a web API may break the dependent applications. This problem exists because old versions of the APIs may no longer be supported, a lack of adequate documentation to upgrade to a newer version, and insufficient communication of changes. In this paper we conducted a case study of evolving Web APIs to investigate what changes are made between...
This paper presents our approach for solving the IEEE VAST 2014 Mini Challenge 1. To solve this challenge we performed different tasks related to data processing and utilized different visualization techniques to explore the data. In this paper we present our application VACI: Visual Analytics for Criminal Investigation and discuss the design and the features.
Understanding information about software artifacts is key to successful Agile software development projects, however, sharing information about artifacts is difficult to achieve amongst team members. There are many information visualization techniques used to help address the difficulties of knowledge sharing, but it is not clear what is the most effective technique. This paper presents the results...
Most software visualization systems and tools for maintenance are designed from a single-user perspective and are bound to the desktop and IDEs. These design decisions do not allow developers to analyze software collaboratively or to easily interact and navigate visualizations within a co-located environment. In my PhD thesis I conducted an exploratory study of how 44 pairs of professional software...
Most software development tools and applications are designed from a single-user perspective and are bound to the desktop and Integrated Development Environments (IDEs). These tools and applications make it hard for developers to analyse and interact with software artifacts collaboratively. We present SourceVisa multi-user collaborative software visualization application for use on large multi-touch...
