An Introduction to TTCN-3
An Introduction to TTCN-3
DescriptionLooking for a solid introduction to the TTCN-3 language and its use? An Introduction to TTCN-3 is just what you need. All the important concepts and constructs of the language are explained in a tutorial style with the emphasis on extensive examples. Throughout the author also addresses the larger picture of how the testing language is related to the overall test system implementation.
- A complete tutorial reference on TTCN-3 with real-world examples and expert advice based on author’s practical industrial experience using the standard.
- Offering a unique insider perspective: Nokia has been instrumental in the development of both the language and tools associated with TTCN-3 and the author is in a unique position to document this experience to help and guide new users.
- And an associated web site that contains code samples from the book and links to the relevant standards documents.
This book provides the perfect companion to the available TTCN-3 language standards filling the gaps in areas such as style guide, structuring, and pointing out the dangers or pitfalls based on the author’s personal TTCN-3 experience from language standardization, tool implementation and applying TTCN-3 for a number of years in the real world. The style and level of the book make it suitable for both engineers learning and applying the language in the real world and students learning TTCN-3 as part of their studies.
