Model-Based Software Testing and Analysis with C#: A Model-based Approach using SpecExplorer
This book teaches new methods for specifying, analyzing, and testing software; essentials for creating high-quality software. These methods increase the automation in each of these steps, making them more timely, more thorough, and more effective. The authors work through several realistic case studies in-depth and detail, using a toolkit built on the C# language and the .NET framework. Readers can also apply the methods in analyzing and testing systems in many other languages and frameworks....
