Adds type tests to runtime test framework

These tests were originally created when the suite was in the examples
repository, this change updates them to the current location, adds
required file headers and also generated a test snapshot with the
results.

It is important to note that one test case is not 100% in synch with the
current implementation, that is cleanly marked in the code (and their
results ignored).

VIATRA

The Eclipse VIATRA framework is a model and data transformation tool that helps move information back and forth in the most efficient way. The platform focuses specifically on event-driven and reactive transformations, which happen on-the-fly as the models change.

VIATRA is a long-running project that incorporates the results of over 15 years of active research and development. VIATRA offers

  • a domain-specific language for graph queries and reactive transformations
  • a Java runtime library which is scalable and easy to embed.

VIATRA primarily targets model-driven engineering tools based on the industry-standard Eclipse Modeling Framework, though it can be used in other contexts as well. VIATRA is an enabling technology and its biggest benefit is the power it gives you to close abstraction gaps. These exist in every data-driven application where structured data needs to be moved across various languages or representation formats.

VIATRA helps you create model transformations that convert objects between languages. Trivial transformations (i.e. copying pieces of data from one document to another) are easy with any general purpose programming language such as Java. In contrast, VIATRA gives you easy-to-use and reusable programming patterns to address non-trivial transformations, such as

  • Changing of structure, i.e. converting a UML model to a source code.
  • Derived data and abstractions: manipulating data during conversion, e.g. filtering information for creating ‘abstract views’
  • Combining multiple sources of information in a significant way to produce a new result, e.g. when creating data streams for dashboards
  • Changing structure: projection of data containing only relevant information during the conversion phrase
