func DefaultGenesisState 

func DefaultGenesisState(fundedAccounts ...string) (map[string]json.RawMessage, keyring.Keyring, error)

DefaultGenesisState returns a default genesis state and a keyring with accounts that have coins. It adds a default "validator" account that is funded and used for the valop address of the single validator. The keyring accounts are based on the fundedAccounts parameter.

func DefaultParams

func DefaultTendermintConfig 

func DefaultTendermintConfig() *config.Config

func GetFreePort 

func GetFreePort() int

func QueryTx 

func QueryTx(clientCtx client.Context, hashHexStr string, prove bool) (*rpctypes.ResultTx, error)

func ReadBlockHeights 

func ReadBlockHeights(ctx context.Context, rpcAddress string, fromHeight, toHeight int64) ([]*types.Block, error)

func ReadBlockchain 

func ReadBlockchain(ctx context.Context, rpcAddress string) ([]*types.Block, error)

func ReadRecentBlocks 

func ReadRecentBlocks(ctx context.Context, rpcAddress string, blocks int64) ([]*types.Block, error)

func SignAndBroadcastTx 

func SignAndBroadcastTx(encCfg encoding.Config, c client.Context, account string, msg ...sdk.Msg) (res *sdk.TxResponse, err error)

SignAndBroadcastTx signs a transaction using the provided account and keyring inside the client.Context, then broadcasts it synchronously.

Types

type Context 

type Context struct {
	client.Context
	// contains filtered or unexported fields
}

func DefaultNetwork 

func DefaultNetwork(t *testing.T) (accounts []string, cctx Context)

DefaultNetwork starts a single valiator celestia-app network using test friendly defaults. These defaults include all default values and genesis params, modified for fast block times and 300 funded accounts. The returned client.Context has a keyring with all of the funded keys stored in it, which can be accessed using the returned accounts.

func New 

func New(
	t testing.TB,
	cparams *tmproto.ConsensusParams,
	tmCfg *config.Config,
	supressLog bool,
	genState map[string]json.RawMessage,
	kr keyring.Keyring,
	chainID string,
) (*node.Node, srvtypes.Application, Context, error)

New creates a ready to use tendermint node that operates a single validator celestia-app network using the provided genesis state. The provided keyring is stored in the client.Context that is returned.

NOTE: the forced delay between blocks, TimeIotaMs in the consensus parameters, is set to the lowest possible value (1ms).

func NewNetwork 

func NewNetwork(
	t testing.TB,
	cparams *tmproto.ConsensusParams,
	tmCfg *config.Config,
	appCfg *srvconfig.Config,
	accounts []string,
	genesisOpts ...GenesisOption,
) (cctx Context, rpcAddr, grpcAddr string)

NewNetwork starts a single valiator celestia-app network using the provided configurations. Provided accounts will be funded and their keys can be accessed in keyring returned client.Context. All rpc, p2p, and grpc addresses in the provided configs are overwritten to use open ports. The node can be accessed via the returned client.Context or via the returned rpc and grpc addresses. Provided genesis options will be applied after all accounts have been initialized.

func StartGRPCServer 

func StartGRPCServer(app srvtypes.Application, appCfg *srvconfig.Config, cctx Context) (Context, func() error, error)

StartGRPCServer starts the grpc server using the provided application and config. A grpc client connection to that server is also added to the client context. The returned function should be used to shutdown the server.

func StartNode 

func StartNode(tmNode *node.Node, cctx Context) (Context, func() error, error)

StartNode starts the tendermint node along with a local core rpc client. The rpc is returned via the client.Context. The function returned should be called during cleanup to teardown the node, core client, along with canceling the internal context.Context in the returned Context.

func (*Context) FillBlock 

func (c *Context) FillBlock(squareSize int, accounts []string, broadcastMode string) (*sdk.TxResponse, error)

FillBlock creates and submits a single transaction that is large enough to create a square of the desired size. broadcast mode indicates if the tx should be submitted async, sync, or block. (see flags.BroadcastModeSync). If broadcast mode is the string zero value, then it will be set to block.

func (*Context) GenesisTime 

func (c *Context) GenesisTime() (time.Time, error)

GenesisTime returns the genesis block time.

func (*Context) GoContext 

func (c *Context) GoContext() context.Context

func (*Context) HeightForTimestamp 

func (c *Context) HeightForTimestamp(timestamp time.Time) (int64, error)

HeightForTimestamp returns the block height for the first block after a given timestamp.

func (*Context) LatestHeight 

func (c *Context) LatestHeight() (int64, error)

LatestHeight returns the latest height of the network or an error if the query fails.

func (*Context) LatestTimestamp 

func (c *Context) LatestTimestamp() (time.Time, error)

LatestTimestamp returns the latest timestamp of the network or an error if the query fails.

func (*Context) PostData 

func (c *Context) PostData(account, broadcastMode string, ns appns.Namespace, blobData []byte) (*sdk.TxResponse, error)

PostData will create and submit PFB transaction containing the namespace and blobData. This function blocks until the PFB has been included in a block and returns an error if the transaction is invalid or is rejected by the mempool.

func (*Context) WaitForBlocks 

func (c *Context) WaitForBlocks(n int64) error

WaitForBlocks waits until n blocks have been committed, returning an error upon failure.

func (*Context) WaitForHeight 

func (c *Context) WaitForHeight(h int64) (int64, error)

WaitForHeight performs a blocking check where it waits for a block to be committed after a given block. If that height is not reached within a timeout, an error is returned. Regardless, the latest height queried is returned.

func (*Context) WaitForHeightWithTimeout 

func (c *Context) WaitForHeightWithTimeout(h int64, t time.Duration) (int64, error)

WaitForHeightWithTimeout is the same as WaitForHeight except the caller can provide a custom timeout.

func (*Context) WaitForNextBlock 

func (c *Context) WaitForNextBlock() error

WaitForNextBlock waits for the next block to be committed, returning an error upon failure.

func (*Context) WaitForTimestamp 

func (c *Context) WaitForTimestamp(t time.Time) (time.Time, error)

WaitForTimestamp performs a blocking check where it waits for a block to be committed after a given timestamp. If that height is not reached within a timeout, an error is returned. Regardless, the latest timestamp queried is returned.

func (*Context) WaitForTimestampWithTimeout 

func (c *Context) WaitForTimestampWithTimeout(t time.Time, d time.Duration) (time.Time, error)

WaitForTimestampWithTimeout waits for a block with a timestamp greater than t.

func (*Context) WaitForTx 

func (c *Context) WaitForTx(hashHexStr string, blocks int) (*rpctypes.ResultTx, error)

type GenesisOption 

type GenesisOption func(state map[string]json.RawMessage) map[string]json.RawMessage

GenesisOption allows for arbitrary changes to be made on the genesis state after initial accounts have been added. It accepts the genesis state as input and is expected to return the modifed genesis as output.

func ImmediateProposals 

func ImmediateProposals(codec codec.Codec) GenesisOption

ImmediateProposals sets the thresholds for getting a gov proposal to very low levels.

func SetBlobParams 

func SetBlobParams(codec codec.Codec, params blobtypes.Params) GenesisOption

SetBlobParams will set the provided blob params as genesis state.
