Functions

func GenerateBlocksOfSize 

func GenerateBlocksOfSize(n int, size int64) []blocks.Block

GenerateBlocksOfSize generates a series of blocks of the given byte size

func GenerateCid 

func GenerateCid() cid.Cid

GenerateCid produces a content identifier.

func GenerateCids 

func GenerateCids(n int) []cid.Cid

GenerateCids produces n content identifiers.

func GenerateMultiaddr added in v0.10.0 

func GenerateMultiaddr() multiaddr.Multiaddr

func GenerateNoDupes added in v0.11.1 

func GenerateNoDupes(gen func() unixfs.DirEntry) unixfs.DirEntry

GenerateNoDupes runs the unixfsnode/testutil generator function repeatedly until it produces a DAG with strictly no duplicate CIDs.

func GeneratePeers 

func GeneratePeers(t *testing.T, n int) []peer.ID

GeneratePeers creates n peer ids.

func GenerateRetrievalCandidates 

func GenerateRetrievalCandidates(t *testing.T, n int, protocols ...metadata.Protocol) []types.RetrievalCandidate

GenerateRetrievalCandidates produces n retrieval candidates

func GenerateRetrievalCandidatesForCID added in v0.8.1 

func GenerateRetrievalCandidatesForCID(t *testing.T, n int, c cid.Cid, protocols ...metadata.Protocol) []types.RetrievalCandidate

GenerateRetrievalCandidates produces n retrieval candidates

func GenerateRetrievalIDs 

func GenerateRetrievalIDs(t *testing.T, n int) []types.RetrievalID

func GenerateRetrievalRequests added in v0.6.0 

func GenerateRetrievalRequests(t *testing.T, n int) []types.RetrievalRequest

func GenerateStrictlyNestedShardedDir added in v0.14.0 

func GenerateStrictlyNestedShardedDir(t *testing.T, linkSys *linking.LinkSystem, randReader io.Reader, targetSize int) unixfs.DirEntry

GenerateStrictlyNestedShardedDir is a wrapper around unixfsnode/testutil.GenerateDirectory that uses dark magic to repeatedly generate a sharded directory until it produces one that is strictly nested. That is, it produces a sharded directory structure with strictly at least one level of sharding with at least two child shards.

Since it is possible to produce a sharded directory that is contained in a single block, this function provides a way to generate a sharded directory for cases where we need to test multi-level sharding.

func RandomBytes(n int64) []byte

RandomBytes returns a byte array of the given size with random values.
