A Testing Environment for Continuous Colormaps [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2021
Many computer science disciplines (e.g., combinatorial optimization, natural language processing, and information retrieval) use standard or established test suites for evaluating algorithms. In visualization, similar approaches have been adopted in some areas (e.g., volume visualization), while user testimonies and empirical studies have been the ...

Functional Testing in the Focal Environment [PDF]

, 2008
This article presents the generation and test case execution under the framework Focal. In the programming language Focal, all properties of the program are written within the source code. These properties are considered, here, as the program specification. We are interested in testing the code against these properties.
