To conduct proper testing of Manufacturing Cloud, the end users need the following items:

Sandbox access: A sandbox is a copy of the production environment that allows users to test changes and features without affecting the live data. Manufacturing Cloud offers different types of sandboxes for different testing purposes, such as learning, pre-release, and base12.

Test data: Test data is a set of realistic and representative data that is used to simulate the actual business scenarios and workflows in Manufacturing Cloud. Test data can be created manually, imported from external sources, or copied from the production environment34.

Process scripts: Process scripts are step-by-step instructions that guide the users through the testing scenarios and expected outcomes. Process scripts help to ensure that the testing is consistent, comprehensive, and aligned with the business requirements . References: Create a Manufacturing Cloud Trial Org, Try Manufacturing Cloud for Free, Create Test Data for Your Full Sandbox, Import Data into Your Org, [Create a Test Plan for Your Salesforce Implementation], [Test Your Salesforce Implementation].
