I'm using visual studio code with node v18. I use structuredClone in my application and it runs fine but when it comes to running a test I get

"ReferenceError: structuredClone is not defined"

I don't know how mocha works, but is it for some reason using an older version of node or is there some other dependency creating an issue?

It's probably a bug, as a turnaround to deep clone your object, you can use JSON.parse & JSON.stringify:

if (global.structuredClone)
    clonedObject = structuredClone(object)
else
    clonedObject = JSON.parse(JSON.stringify(object))
