Testing

In MPS, the language designer can implement tests targeting different language aspects. We decided to implement tests targeting primarily the Editor aspect as this should cover the user’s work complexly (typing, using different kinds of actions, intentions and so on).

We also tested the language by implementing example programs based on our base language. These tests covered the whole process of program development, i.e. writing the code utilizing the language aspects in combination, using the standard libraries and generating and running the C# source code.

How to Setup and Run Tests

Set MPS path variable project_home to your project location:

1. Go to File -> Settings -> Appearance & Behaviour -> Path Variables
2. Add a new variable or modify an already existing variable with the name project_home
3. Set its value to the project's location (e.g. c:\Users\<username>\MPSProjects\mpscs)

Run Tests

1. Right-click on the solution CsBaseLanguage.tests or on the model EditorAndStructure@tests located in the virtual folder CsBaseLanguage.tests inside tests in the solution CsBaseLanguage.tests
2. Trigger Run Tests in CsBaseLanguage.tests
