Testing the implementation of Syzygy

[konsolas]

I'm currently implementing Syzygy tablebases.

Are there any notable test positions which engines typically need tablebases to play well in, which could be used to test the implementation of Syzygy?

First make sure that probing TB positions returns the correct results (e.g. by comparing with what SF returns when given the 'd' command).

Once that works, you could try some of the "Longest phases" positions you can find at https://syzygy-tables.info/ by setting up a position with the material you like to test on.
