How to unit Test for Xtext

Question

I have to test my grammar (written with Xtext). I've see it is possible with use of unit test, but I can't find a good tutorial about it.

Can you help me?

A unit test verifies that some unit of code is compliant with the specification, usually beyond plain compiletime errors. What exactly do you want to unit test? – Stamey

Answer 1

There are several links about this.

• The official tutorials have chapter about special Xtext/Junit support: Unit Testing the Language

• Xtext-Utils has some tools

• Xpect provides a DSL for unittesting DSLs. Slides here (Looks interesting)

• The slides of Markus Voelter "Testing DSLs" explain stuff.
