End-to-End Sandbox
The MHHS Programme published the End-to-End (E2E) Sandbox Test Data Approach & Plan for industry consultation.
This consultation closed on Friday 6 June 2025. Thank you to everyone who responded.
The End-to-End Sandbox Test Data Approach & Plan document aims to define a test data approach and provides a view of specific data requirements that will support Sandbox Testing using the User Integration Testing (UIT) environment.
Sandbox testing in the UIT environment is provided on the basis of being supported by the same Test Harnesses used for Non-Systems Integration Testing (Non-SIT) Qualification Testing, it therefore relies heavily on the Qualification Test Data Approach and Plan documents for both Non-SIT Licensed Distribution System Operators (LDSOs) and Non-SIT Supplier & Agents, as the process used for E2E Sandbox in the UIT environment will essentially be a repeat of the same approach as used for Qualification Testing.
This document is a child document of the E2E Sandbox Guidance document which establishes a clear scope for Sandbox Testing. So, you should read this document in conjunction with the E2E Sandbox Guidance document, which is available further down this page.
All comments were triaged and the document was presented for discussion at the Qualification Working Group (QWG) on Tuesday 10 June 2025. On Thursday 19 June 2025, the Qualification Advisory Group (QAG) formally approved the document, which you can view below:
