Are wormholes available on the test server?

Yes, they are. But as there are basically no active players, you can only find entrances, as exits only spawn the moment someone triggers a Wormhole. And as you usually depend on the static WH to empire space wormholes than the other way around, it´s hard to find those Empire to WH space wormholes

With the command /moveme (just send it in any chat channel), you can be teleported to one of six WH’s with one click. From there you can continue scanning, for example.
