VVP provides the functionality to validate that a VNF Heat package is compliant with the ONAP VNF Heat Template Requirements from the ONAP VNFRQTS project. The ONAP VNF Heat Template Requirements are a set of restrictions and guidelines that a heat-based VNF must adhere to for ONAP compliance. ONAP compliance ensures a VNF can be properly modeled, instantiated, and inventoried by the ONAP platform.

The VVP validation-scripts is a set of python-based tests and are invoked by using pytest. Each test is marked with a specific requirement(s) from the VNFRQTS project. After executing the validation scripts, a validation report is constructed and provided to the user with details about each violation (if any). These details include the template the violation was found in, the test and module name, and the requirement number and text from the ONAP VNF Heat Template Requirements.
