A Guide to Using and Creating Domain Specific Languages for Testing

Domain-specific languages as a technology are unexceptional: they’ve been around for a while, and there are many of them. What is intriguing, is taking a look at how we can use domain-specific language as a tool.

In this talk, we will look at the benefits of using DSLs, how you might go about designing your own, what you might encounter in the process, and lessons learned. This discussion will Include what you’d need to build, and what is available open source, we’ll look at DSLs in action, and where you can go to learn more.

Gherkin, which we’ll build upon as a core language, is often associated with Business Driven Development. BDD is a methodology, it focuses on the “how”, when compared to food it is like eating paleo-locavore. Gherkin, on the other hand, is a tool, like a frying pan. You can use a frying pan to cook, even if you don’t eat paleo; similarly, Gherkin is a functional tool even when not using the BDD methodology, while in no way diminishing the value to BDD.

We will look at some reasons you might want to implement your own DSLs:
- Reduce the barrier to entry into test automation and BDD;
- Improve trust with customers as testing becomes transparent;
- Create an entry point of Domain Driven Design for existing architectures (it covers Ubiquitous Language, Model-Driven Design, Entities, Repositories, Bounded Context, Context Map, Anti-corruption Layer); and,
- Speed up test creation.
