None of those by default, Pulsar tends to stick to being an editor with as much as you need but not more by default. However one good thing about forking Atom was that we kept all the packages that were published to atom.io (more than 10k of them). You can browse them the PPR (Pulsar Package Registry) which was reverse engineered from Atom's closed source backend from scratch before they took down the site - https://web.pulsar-edit.dev/.

Specifically there are a bunch of remote edit packages that work over SSH, a ton of Docker packages and there are plenty of debugging packages both generic and language specific and there are indeed test runner packages.

I won't say I guarantee all of these will work but our Discord channel in particular is rather active so people more knowledgeable than I might well be able to help out, its a friendly place. We have other social channels as well should you prefer them.
