[FEATURE] Provide a way to verify and test templates in CI #512
Description
Is your feature request related to a problem?
Writing a template for the Project Builder is rather easy. But with constantly evolving templates and an ever improving Project Builder who is to say that a template still works as expected?
Describe the solution you'd like
There should be a way to have templates be validated and tested against the Project Builder and against expected outcomes both locally and in the CI. That's why I'm proposing to come with such a feature.
Describe alternatives you've considered
Until now I've tested templates with the composer simulate manually. That's all good but it could be better.
