I use Kepware Server , it restarts every 2H, but for testing this is not a problem. In addition, you can connect the PLC. In Matrikon, you can also do this, but with big restrictions.

If you check out www.opcfoundation.org , you can find tools for building OPC clients and servers. I don’t remember which ones, but some of them come with "simulation servers" so you can check your code.
