Create an integration test that sets integer properties on an instance of a VFC in a service, verifies the generated tosca is correct and the service can be be exported, then imported and the generated tosca for the imported service is correct.

The following should be used in the property values:

• integer value
• get_property referencing a SELF property
• get_property referencing a property of in instance property
• get_property referencing a sub property of an instance property
• get_attribute referencing a SELF property
• get_attribute referencing a property of in instance property
• get_attribute referencing a sub property of an instance property
• get_input
• yaml

Each of the following constraints shall be defined on at least one of the properties where a tosca function value is being set (to ensure the constraint is not validated when a TOSAC function value is given):

• equal
• greater_than
• greater_or_equal
• less_than
• less_or_equal
• in_range
• valid_values
