This has been verified locally on a windows machine by Aarathy.

Need to investigate!

OK so reading into the error messages more, and reading what future docs say...

The error message on windows is:

Error in makeForkCluster(nnodes = spec, ...): fork clusters are not supported on Windows

Which happens with this code in test_future.R

cl <- parallel::makeCluster(2L, type = "FORK")

That is what is causing the first error, so I can skip that test on windows...let's see how that goes.
