Functions

func DefaultGenesis 

func DefaultGenesis() (genesis types.GenesisDoc)

DefaultGenesis returns a genesis doc using configuration from the local net with a genesis time equivalent to unix epoch + 1 nanosecond. We specifically use non-zero because stateful orders validate that block time is non-zero (https://github.com/dydxprotocol/v4-chain/protocol/blob/ 84a046554ab1b4725475500d94a0b3179fdd18c2/x/clob/keeper/stateful_order_state.go#L237).

func DefaultTestApp 

func DefaultTestApp(customFlags map[string]interface{}) *app.App

Create an instance of app.App with default settings, suitable for unit testing, with the option to override specific flags.

func MustMakeCheckTx 

func MustMakeCheckTx(
	ctx sdk.Context,
	app *app.App,
	options MustMakeCheckTxOptions,
	messages ...sdk.Msg,
) abcitypes.RequestCheckTx

MustMakeCheckTx creates a signed RequestCheckTx for the provided message. The message must use one of the hard-coded well known subaccount owners otherwise this will panic.

func MustMakeCheckTxWithPrivKeySupplier 

func MustMakeCheckTxWithPrivKeySupplier(
	ctx sdk.Context,
	app *app.App,
	options MustMakeCheckTxOptions,
	privKeySupplier func(accAddress string) cryptotypes.PrivKey,
	messages ...sdk.Msg,
) abcitypes.RequestCheckTx

MustMakeCheckTxWithPrivKeySupplier creates a signed RequestCheckTx for the provided message. The `privKeySupplier` must provide a valid private key that matches the supplied account address.

func MustMakeCheckTxsWithClobMsg 

func MustMakeCheckTxsWithClobMsg[T clobtypes.MsgPlaceOrder | clobtypes.MsgCancelOrder](
	ctx sdk.Context,
	app *app.App,
	messages ...T,
) []abcitypes.RequestCheckTx

MustMakeCheckTxsWithClobMsg creates one signed RequestCheckTx for each msg passed in. The messsage must use one of the hard-coded well known subaccount owners otherwise this will panic.

func MustMakeCheckTxsWithSdkMsg 

func MustMakeCheckTxsWithSdkMsg(
	ctx sdk.Context,
	app *app.App,
	options MustMakeCheckTxOptions,
	messages ...sdk.Msg,
) (checkTxs []abcitypes.RequestCheckTx)

MustMakeCheckTxsWithSdkMsg creates one signed RequestCheckTx for each msg passed in. The messsage must use one of the hard-coded well known subaccount owners otherwise this will panic.

func UpdateGenesisDocWithAppStateForModule 

func UpdateGenesisDocWithAppStateForModule[T GenesisStates](genesisDoc *types.GenesisDoc, fn func(genesisState *T))

UpdateGenesisDocWithAppStateForModule updates the supplied genesis doc using the provided function. The function type (any one of the well known GenesisStates) is used to derive which module will be updated. Will panic if there is an error in marshalling or unmarshalling the app state.

Types

type AdvanceToBlockOptions 

type AdvanceToBlockOptions struct {
	// The time associated with the block. If left at the default value then block time will be left unchanged.
	BlockTime time.Time

	// RequestPrepareProposalTxsOverride allows overriding the txs that gets passed into the
	// PrepareProposalHandler. This is useful for testing scenarios where unintended msg txs
	// end up in the mempool (i.e. CheckTx failed to filter bad msg txs out).
	RequestPrepareProposalTxsOverride [][]byte

	// RequestProcessProposalTxsOverride allows overriding the txs that gets passed into the
	// ProcessProposalHandler. This is useful for testing scenarios where bad validators end
	// up proposing an invalid block proposal.
	RequestProcessProposalTxsOverride [][]byte

	// DeliverTxsOverride allows overriding the TestApp from being the block proposer and
	// allows simulating transactions that were agreed to upon consensus to be delivered.
	// This skips the PrepareProposal and ProcessProposal phase.
	DeliverTxsOverride [][]byte

	ValidateRespPrepare ValidateResponsePrepareProposalFn
	ValidateRespProcess ValidateResponseProcessProposalFn
	ValidateDeliverTxs  ValidateDeliverTxsFn
}

AdvanceToBlockOptions is a struct containing options for AdvanceToBlock.* functions.

type AppCreatorFn 

type AppCreatorFn func() *app.App

Used to instantiate new instances of the App.

func DefaultTestAppCreatorFn 

func DefaultTestAppCreatorFn(customFlags map[string]interface{}) AppCreatorFn

DefaultTestAppCreatorFn is a wrapper function around DefaultTestApp using the specified custom flags.

type ExecuteCheckTxs 

type ExecuteCheckTxs func(ctx sdk.Context, app *app.App) (stop bool)

ExecuteCheckTxs is invoked once per block. Returning true will halt execution. The provided context will be a new CheckTx context using the last committed block height.

type GenesisDocCreatorFn 

type GenesisDocCreatorFn func() (genesis types.GenesisDoc)

Used to instantiate new instances of the genesis doc.

type GenesisStates 

type GenesisStates interface {
	authtypes.GenesisState |
		banktypes.GenesisState |
		perptypes.GenesisState |
		feetiertypes.GenesisState |
		stattypes.GenesisState |
		vesttypes.GenesisState |
		rewardstypes.GenesisState |
		blocktimetypes.GenesisState |
		clobtypes.GenesisState |
		pricestypes.GenesisState |
		satypes.GenesisState |
		assettypes.GenesisState |
		epochstypes.GenesisState |
		sendingtypes.GenesisState |
		delaymsgtypes.GenesisState |
		bridgetypes.GenesisState
}

GenesisStates is a type constraint for all well known genesis state types.

type MustMakeCheckTxOptions 

type MustMakeCheckTxOptions struct {
	// AccAddressForSigning is the account that's used to sign the transaction.
	AccAddressForSigning string
	// AccSequenceNumberForSigning is the account sequence number that's used to sign the transaction.
	AccSequenceNumberForSigning uint64
	// Amount of Gas for the transaction.
	Gas uint64
}

MustMakeCheckTxOptions is a struct containing options for MustMakeCheckTx.* functions.

type TestApp 

type TestApp struct {
	// Should only be used to fetch read only state, all mutations should preferrably happen through Genesis state,
	// TestApp.CheckTx, and block proposals.
	// TODO(CLOB-545): Hide App and copy the pointers to keepers to be prevent incorrect usage of App.CheckTx over
	// TestApp.CheckTx.
	App *app.App
	// contains filtered or unexported fields
}

A TestApp used to executed ABCI++ flows. Note that callers should invoke `TestApp.CheckTx` over `TestApp.App.CheckTx` to ensure that the transaction is added to a "mempool" that will be considered during the Prepare/Process proposal phase.

Note that TestApp.CheckTx is thread safe. All other methods are not thread safe.

func (*TestApp) AdvanceToBlock 

func (tApp *TestApp) AdvanceToBlock(
	block uint32,
	options AdvanceToBlockOptions,
) sdk.Context

AdvanceToBlock advances the chain to the specified block and block time. If the specified block is the current block, simply returns the current context. For example, block = 10, t = 90 will advance to a block with height 10 and with a time of 90.

func (*TestApp) Builder 

func (tApp *TestApp) Builder() TestAppBuilder

func (*TestApp) CheckTx 

func (tApp *TestApp) CheckTx(req abcitypes.RequestCheckTx) abcitypes.ResponseCheckTx

CheckTx adds the transaction to a test specific "mempool" that will be used to deliver the transaction during Prepare/Process proposal. Note that this must be invoked over TestApp.App.CheckTx as the transaction will not be added to the "mempool" causing the transaction to not be supplied during the Prepare/Process proposal phase.

This method is thread-safe.

func (*TestApp) GetBlockHeight 

func (tApp *TestApp) GetBlockHeight() int64

GetBlockHeight fetches the current block height of the test app.

func (*TestApp) GetHalted 

func (tApp *TestApp) GetHalted() bool

GetHalted fetches the halted flag.

func (*TestApp) GetHeader 

func (tApp *TestApp) GetHeader() tmproto.Header

GetHeader fetches the current header of the test app.

func (*TestApp) InitChain 

func (tApp *TestApp) InitChain() sdk.Context

InitChain initializes the chain. Will panic if initialized more than once.

func (*TestApp) PrepareProposal 

func (tApp *TestApp) PrepareProposal() abcitypes.ResponsePrepareProposal

PrepareProposal creates an abci `RequestPrepareProposal` using the current state of the chain and calls the PrepareProposal handler to return an abci `ResponsePrepareProposal`.

func (*TestApp) Reset 

func (tApp *TestApp) Reset()

Reset resets the chain such that it can be initialized and executed again.

type TestAppBuilder 

type TestAppBuilder struct {
	// contains filtered or unexported fields
}

A builder containing fields necessary for the TestApp.

Note that we specifically use value receivers for the With... methods because we want to make the builder instances immutable.

func NewTestAppBuilder 

func NewTestAppBuilder() TestAppBuilder

NewTestAppBuilder returns a new builder for TestApp.

The default instance will return a builder using:

  • DefaultGenesis
  • DefaultTestAppCreatorFn with no custom flags
  • an ExecuteCheckTxs function that will stop on after the first block

	ctx sdk.Context,
	request abcitypes.RequestDeliverTx,
	response abcitypes.ResponseDeliverTx,
