Motivation
Closes #4190
Solution
Catch reverts with
MAGIC_ASSUME
, regenerate latest calldata and increaseassume_rejects_counter
. Once counter goes beyond configuredmax_assume_rejects
, test fails.I've changed
InvariantFuzzError
to be an enum, because we don't need data it holds right now forMaxAssumeRejects
failures.Also changed
invariant_strat
a bit, currently it always returns Vec with one element, it seemed a bit confusing at first glance, so I changed it to return just a single input.
