Description
I often encounter this exception, especially when I previously ran pytest and a syntax error prevented it to run.
File "/usr/local/lib/python3.7/site-packages/random_order/plugin.py", line 60, in pytest_collection_modifyitems
INTERNALERROR> process_failed_first_last_failed(session, config, items)
INTERNALERROR> File "/usr/local/lib/python3.7/site-packages/random_order/cache.py", line 28, in process_failed_first_last_failed
INTERNALERROR> raise NotImplementedError()
INTERNALERROR> NotImplementedError

Research direction
Start by reproducing the reported failure with pytest after a syntax error, then read pytest-random-order/plugin.py around pytest_collection_modifyitems and cache.py around process_failed_first_last_failed. Trace how the cache is used during collection and define the expected behavior when the previous run could not collect tests; done means pytest no longer raises this internal NotImplementedError.
