tSQLt test problem for some DDL queries

I am a SQL Server DBA. To automate some of my daily tasks, I need to write stored procedures. Creating functionality without testing does not make sense to me. For creating and running my tests, I used the tSQLt Framework. I had to create a database during the test. "CREATE DATABASE" is not permitted inside a multi-statement transaction, but all tests are automatically run inside a transaction within tSQLt Framework. Naturally, I can set up a test database manually before running the test, but the test cannot depend on the environment in which it will be executed. How should this be approached?
