The 5G EVE Experimentation Portal is the main visible component available for experimenters willing to run their experiments on top of 5G EVE infrastructure. All the direct interaction will be done through the Portal, but the Portal is just the front-end of the Testing-as-a-Service environment that 5G EVE is creating. In particular, the testing and validation procedures are not governed by the Portal, but by the WP5 modules conforming the Testing and Validation framework to which this Deliverable is dedicated. Deliverable D5.2 – Model-based testing framework – represents the main outcome of Task 5.1 – Overall methodology framework for model-based testing –, and specifies a testing and validation architecture capable of providing the Testing-as-a-Service (TaaS) offer expected from the 5G EVE platform and site facilities.
