I have written about Test-DbaLastBackup in posts here, here and here. They have been Windows only posts.
With SQL Server vNext CTP 1.4 now available and providing SQL Agent capability on Linux, I wrote here about using Ola Hallengrens scripts on Linux SQL Servers so can Test-DbaLastBackup work with Linux?

Yes it does!!
and I caught the database being restored in SSMS as well

Happy Automating
