}

ExpectInvocation is a pattern for a message invocation within the VM. The To and Method fields must be supplied. Exitcode defaults to exitcode.Ok. All other field are optional, where a nil or Undef value indicates that any value will match. SubInvocations will be matched recursively.

type VM 

type VM struct {
	ActorImpls ActorImplLookup
	// contains filtered or unexported fields
}

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)

AdvanceByDeadline creates a new VM advanced to an epoch specified by the predicate while keeping the miner state upu-to-date by running a cron at the end of each deadline period.

func AdvanceByDeadlineTillEpoch 

func AdvanceByDeadlineTillEpoch(t *testing.T, v *VM, minerIDAddr address.Address, e abi.ChainEpoch) (*VM, *dline.Info)

Advances by deadline until e is contained within the deadline period represented by the returned deadline info. The VM returned will be set to the last deadline close, not at e.

func AdvanceByDeadlineTillIndex 

func AdvanceByDeadlineTillIndex(t *testing.T, v *VM, minerIDAddr address.Address, i uint64) (*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.

func AdvanceTillProvingDeadline 

func AdvanceTillProvingDeadline(t *testing.T, v *VM, minerIDAddress address.Address, sectorNumber abi.SectorNumber) (*dline.Info, uint64, *VM)

Advance to the epoch when the sector is due to be proven. Returns the deadline info for proving deadline for sector, partition index of sector, and a VM at the opening of the deadline (ready for SubmitWindowedPoSt).

func NewVM 

func NewVM(ctx context.Context, actorImpls ActorImplLookup, store adt.Store) *VM

NewVM creates a new runtime for executing messages.
