) (abci.ResponseDeliverTx, error)

Delegate delivers a delegate tx

func DeliverEthTx 

func DeliverEthTx(
	appEvmos *app.Evmos,
	priv cryptotypes.PrivKey,
	msgs ...sdk.Msg,
) (abci.ResponseDeliverTx, error)

DeliverEthTx generates and broadcasts a Cosmos Tx populated with MsgEthereumTx messages. If a private key is provided, it will attempt to sign all messages with the given private key, otherwise, it will assume the messages have already been signed.

func DeliverTx 

func DeliverTx(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	priv cryptotypes.PrivKey,
	gasPrice *sdkmath.Int,
	msgs ...sdk.Msg,
) (abci.ResponseDeliverTx, error)

DeliverTx delivers a cosmos tx for a given set of msgs

func DeployContract 

func DeployContract(
	ctx sdk.Context,
	evmosApp *app.Evmos,
	priv cryptotypes.PrivKey,
	queryClientEvm evm.QueryClient,
	contract evm.CompiledContract,
	constructorArgs ...interface{},
) (common.Address, error)

DeployContract deploys a contract with the provided private key, compiled contract data and constructor arguments

func DeployContractWithFactory 

func DeployContractWithFactory(
	ctx sdk.Context,
	evmosApp *app.Evmos,
	priv cryptotypes.PrivKey,
	factoryAddress common.Address,
) (common.Address, abci.ResponseDeliverTx, error)

DeployContractWithFactory deploys a contract using a contract factory with the provided factoryAddress

func FundAccount 

func FundAccount(ctx sdk.Context, bankKeeper bankkeeper.Keeper, addr sdk.AccAddress, amounts sdk.Coins) error

FundAccount is a utility function that funds an account by minting and sending the coins to the address.

func FundAccountWithBaseDenom 

func FundAccountWithBaseDenom(ctx sdk.Context, bankKeeper bankkeeper.Keeper, addr sdk.AccAddress, amount int64) error

FundAccountWithBaseDenom is a utility function that uses the FundAccount function to fund an account with the default Evmos denomination.

func FundModuleAccount 

func FundModuleAccount(ctx sdk.Context, bankKeeper bankkeeper.Keeper, recipientMod string, amounts sdk.Coins) error

FundModuleAccount is a utility function that funds a module account by minting and sending the coins to the address.

func GetTotalDelegationRewards 

func GetTotalDelegationRewards(ctx sdk.Context, distributionKeeper distributionkeeper.Keeper, addr sdk.AccAddress) (sdk.DecCoins, error)

GetTotalDelegationRewards returns the total delegation rewards that are currently outstanding for the given address.

func NewHeader 

func NewHeader(
	height int64,
	blockTime time.Time,
	chainID string,
	proposer sdk.ConsAddress,
	appHash,
	validatorHash []byte,
) tmproto.Header

NewHeader creates a new Tendermint header for testing purposes.

func NewStateDB 

func NewStateDB(ctx sdk.Context, evmKeeper evm.EVMKeeper) *statedb.StateDB

NewStateDB returns a new StateDB for testing purposes.

func NextFn 

func NextFn(ctx sdk.Context, _ sdk.Tx, _ bool) (sdk.Context, error)

NextFn is a no-op function that returns the context and no error in order to mock the next function in the AnteHandler chain.

It can be used in unit tests when calling a decorator's AnteHandle method, e.g. `dec.AnteHandle(ctx, tx, false, NextFn)`

func PrepareAccountsForDelegationRewards 

func PrepareAccountsForDelegationRewards(t *testing.T, ctx sdk.Context, app *app.Evmos, addr sdk.AccAddress, balance sdkmath.Int, rewards ...sdkmath.Int) (sdk.Context, error)

PrepareAccountsForDelegationRewards prepares the test suite for testing to withdraw delegation rewards.

Balance is the amount of tokens that will be left in the account after the setup is done. For each defined reward, a validator is created and tokens are allocated to it using the distribution keeper, such that the given amount of tokens is outstanding as a staking reward for the account.

The setup is done in the following way:

  • Fund the account with the given address with the given balance.
  • If the given balance is zero, the account will be created with zero balance.

For every reward defined in the rewards argument, the following steps are executed:

  • Set up a validator with zero commission and delegate to it -> the account delegation will be 50% of the total delegation.
  • Allocate rewards to the validator.

The function returns the updated context along with a potential error.

func SubmitProposal 

func SubmitProposal(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	pk *ethsecp256k1.PrivKey,
	content govv1beta1.Content,
	eventNum int,
) (id uint64, err error)

SubmitProposal delivers a submit proposal tx for a given gov content. Depending on the content type, the eventNum needs to specify submit_proposal event.

func ValidateAnteForMsgs 

func ValidateAnteForMsgs(ctx sdk.Context, dec sdk.AnteDecorator, msgs ...sdk.Msg) error

ValidateAnteForMsgs is a helper function, which takes in an AnteDecorator as well as 1 or more messages, builds a transaction containing these messages, and returns any error that the AnteHandler might return.

func Vote 

func Vote(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	priv *ethsecp256k1.PrivKey,
	proposalID uint64,
	voteOption govv1beta1.VoteOption,
) (abci.ResponseDeliverTx, error)

Vote delivers a vote tx with the VoteOption "yes"
