Is there a recommended way of using mount in multithreaded scenarios? For e.g. let us say I hold some config data in a state, and I want to run a number of tests in parallel each with different config. Is the state thread local by default?

nope, the state is a normal Var

Maybe https://github.com/tolitius/yurt can help you, @rkaippully

I usually just redef stuff in my tests

but then I'm not very civilized anyway

Yurt looks interesting. I’ll take a look. Thanks
