Specification by Example: Writing Valuable Specs
Utrecht
di 30 jun. 2026
en 1 andere data
With Specification by Example, functional requirements, specifications, and acceptance tests become the same thing
Specification by Example is an approach to software development based on specifications that are enhanced with realistic examples. Using this approach, teams bridge the communication gap that often lies between stakeholders and developers.
Applying Specification by Example provides important benefits:
- a greater chance that software development teams deliver software that enable the stakeholders to effectively achieve its goals
- concrete and efficiently validated requirements
- reduction of the amount of rework
- reliable “living” system documentation
Target audience: Members of agile working teams.
The basis for the training is formed by the work of Gojko Adzic the author of Specification by Example.
The emphasis of the training lies on practical exercises.
After completing this course you will have
- More understanding of the concepts that form the basis of Specification by Example and Acceptance Test Driven Development
- Practical experience in extending specifications with examples
- More understanding in the way which you can use examples as functional acceptance tests
- Insight into the way you can further develop the combination of specification…

TypeScript: From Zero to Hero
Veenendaal
ma 17 aug. 2026
Learn to develop maintainable JavaScript applications with TypeScript
Learn to develop maintainable JavaScript applications with TypeScript.
We develop ever larger JavaScript applications today. Unfortunately this language is not well-suited for this purpose. That's why we use TypeScript. TypeScript helps by expanding the JavaScript syntax with a type system. As a result, you can detect errors earlier and enjoy better tooling support. This all leads to higher efficiency and code quality.
In this training you start by learning the basics of TypeScript, including primitive types and functions. Then you'll be introduced to more advanced concepts, like literal types, interfaces, and generics. In the end you will master the principle of structural typing with mapped types and conditional types.
There is plenty of time to practice, as you will implement these concepts in an application you build from the ground up.
Did you know that:
- false === true is a compile error?
- interfaces don't exist in JavaScript?
- public and private are a myth?
- a class can implement another class?
- an interface can extend a class?
- defining a class does two things?
- TypeScript is not a typesafe language?
- there exists a type called never?
- TypeS…

UML Essentials: From Use Cases to Class Diagrams
An overview of Object Technology and Terminology with UML for Technical Managers, users and non-developers
This course has been designed for technical managers, users and other non-development staff who need an understanding and reading knowledge of the UML. It introduces the principles and benefits of object technology, and provides an overview of the terminology and the graphical notation of UML. In addition, it introduces the issues involved in managing Unified projects, and in managing object technology in general within an organisation.
Although attending the course is an ideal way to learn about and evaluate the UML, the course does not enable delegates to use the approach for development. Developers require our Object-Oriented Analysis and Design using the Unified Modelling Language course (OOUML), which includes the much greater detail required.
On Completion, Delegates will be able to
- Explain what object technology is
- Understand the principal terminology involved in object technology and UML
- Read the UML graphical notation
- Understand the issues involved in object-oriented project management
Overview
• Analysis and design
• Object orientation
• UML
Diagrams
• Business processes
• Use case diagram
• Activity diagram
• Class diagram
