const RandString = "i_am_random_____i_am_random_____"

This is set to match the test vector default randomness value. If set differently it will cause all generated conformance tests over randomness syscalls to fail. https://github.com/filecoin-project/test-vectors/blob/master/schema/schema_randomness.go#L76

VM is a simplified message execution framework for the purposes of testing inter-actor communication. The VM maintains actor state and can be used to simulate message validation for a single block or tipset. The VM does not track gas charges, provide working syscalls, validate message nonces and many other things that a compliant VM needs to do.

func AdvanceByDeadline 

func AdvanceByDeadline(t *testing.T, v *VM, minerIDAddr address.Address, predicate advanceDeadlinePredicate) (*VM, *dline.Info)

Advances by deadline until the deadline index matches the given index. The vm returned will be set to the close epoch of the previous deadline.
