# SMS test environments

Descriptions and links for the NHS Digital SMS test environments.

## Opentest (Non-N3 / HSCN using VPN)

The Opentest system is a platform based on Spine 2 Core, to which healthcare applications developers can connect their systems. Unlike the formal “path-to-live” environments there are very few pre-conditions (you do not even have to have a working system yet). Environments based on the platform are hosted off the NHS “N3 ” network (or its successor – HSCN) therefore the Information Governance Statement of Conformance (IGSoC) is not required before use.

## Path-to-Live formal development and integration environments (N3 / HSCN )

The formal path-to-live environments are hosted on N3/HSCN and as such the Information Governance Statement of Conformance (IGSoC) is required before use, as this is a predicate to connecting to N3/HSCN.
