System diagram procedures are currently included in the code coverage results

The system diagram procedures are currently included in the code coverage results.
These shoudn't be included as they are system procedures so we shouldn't need to write tests for them, and it negatively impacts the total coverage %.

I believe they can be recognised by either their name (sp_%diagram) or by the extended property microsoft_database_tools_support.


I am currently using Code Coverage as part of the RedGate SQLTest plugin.
I had approached RedGate about this and they pointed me to here :)

@GoEddie

Start by locating the code that identifies stored procedures and assembles code coverage results; the issue suggests matching sp_%diagram names or the microsoft_database_tools_support extended property. Verify that system diagram procedures are excluded from coverage while ordinary procedures remain included, and add or update the relevant coverage tests if the repository provides them.
