This looks like it should work. If you want to be sure to catch any dashboard / pegasus isolation issues, you could run dashboard locally with dashboard_enable_pegasus: false and then run pegasus separately.

Out of curiosity, in which kind of tests (unit tests or ui tests) was pegasus code previously able to access Script?

[Hamms]

Oh, that's good to know! I wasn't aware it was that easy to run in isolation.

I don't think pegasus was able to access Script in any test environment; in fact, I actually wrote the test first, before moving the functionality to ScriptConstant and verified that it failed with the NameError. The context in which pegasus was able to access Script was just running the server locally, which gave me false confidence that it would just work.

makes sense, thanks for explaining. to run separately/locally, you may also have to set pegasus_port: 3001
