+        This test is specifically for SQL Server 2017 where the encryption key
+        operations have issues after removing encrypted information.
+
+        This test runs Set-SqlDscRSDatabaseConnection to re-establish the database
+        connection after Post.EncryptedInformation.RS.Integration.Tests.ps1 has
+        removed encrypted information.
+
+        This test runs after Post.EncryptedInformation.RS.Integration.Tests.ps1 and
