/*
Testing the Template Topology API should be very thin, given the following
assumptions:
- Template topology API is relying on Retry's logic.
- The templates themselves are an actual representation of the initial
state in VID's backend. This is all the knowledge that used to create
a service in the first time. So if API is fed with same state, it already
should be able to reiterate another instance.
The tests below will verify that:
- A request resulting from Cypress test on "instantiation-templates.e2e.ts"
is accepted by API endpoint
- A valid "regular" (not from template) request, yields a template that a
Cypress is able to deploy.
These two tests are, technically, cyclic.
Currently the only test below is shortcutting the both tests, by checking
that feeding a Cypress input yields a Template that is the same. This is
not perfect, but currently what we have.
