360 instruction test suite / unit tests?

Is there a test suite to verify that all the S/360 instructions are operating correctly, either original IBM diagnostics or unit tests that are part of Hercules?
 

 The reason I ask is I'm writing an IBM S/360 Model 50 emulator running at the Microcode level, and I figured if there are pre-existing tests available, I could stop writing so many unit tests to test each instruction. I looked at the Hercules source code, but couldn't find tests.
 

 Thanks,
 Ken
