Functions

func GenerateAddress 

func GenerateAddress() common.Address

GenerateAddress generates an Ethereum address.

func NewAddrKey 

func NewAddrKey() (common.Address, *ethsecp256k1.PrivKey)

NewAddrKey generates an Ethereum address and its corresponding private key.

Types

type CallType 

type CallType int

CallType indicates which type of contract call is made during the integration tests.

type ContractData 

type ContractData struct {
	Address common.Address
	ABI     abi.ABI
}

ContractData is a helper struct to hold the address and ABI for a given contract.

type ContractsData 

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

ContractsData is a helper struct to hold the addresses and ABIs for the different contract instances that are subject to testing here.

func (ContractsData) GetContractData 

func (cd ContractsData) GetContractData(callType CallType) ContractData

GetContractData is a helper function to return the contract data for a given call type.

type ExpectedBalance 

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

ExpectedBalance is a helper struct to check the balances of accounts.

type IntegrationTestSuite 

type IntegrationTestSuite struct {
	suite.Suite
	// contains filtered or unexported fields
}

func NewIntegrationTestSuite 

func NewIntegrationTestSuite(create network.CreateEvmApp, options ...network.ConfigOption) *IntegrationTestSuite

func (*IntegrationTestSuite) ExpectAllowanceForContract 

func (is *IntegrationTestSuite) ExpectAllowanceForContract(
	callType CallType, contractData ContractsData, owner, spender common.Address, expAmount *big.Int,
)

ExpectAllowanceForContract is a helper function to check that a SendAuthorization exists for a given owner and spender combination for a given amount and optionally an access list.

func (*IntegrationTestSuite) ExpectBalances 

func (is *IntegrationTestSuite) ExpectBalances(expBalances []ExpectedBalance)

ExpectBalances is a helper function to check if the balances of the given accounts are as expected.

func (*IntegrationTestSuite) ExpectBalancesForContract 

func (is *IntegrationTestSuite) ExpectBalancesForContract(callType CallType, contractData ContractsData, expBalances []ExpectedBalance)

ExpectBalancesForContract is a helper function to check expected balances for given accounts depending on the call type.

func (*IntegrationTestSuite) ExpectBalancesForERC20 

func (is *IntegrationTestSuite) ExpectBalancesForERC20(callType CallType, contractData ContractsData, expBalances []ExpectedBalance)

ExpectBalancesForERC20 is a helper function to check expected balances for given accounts when using the ERC20 contract.

func (*IntegrationTestSuite) ExpectTrueToBeReturned 

func (is *IntegrationTestSuite) ExpectTrueToBeReturned(res *evmtypes.MsgEthereumTxResponse, methodName string)

ExpectTrueToBeReturned is a helper function to check that the precompile returns true in the ethereum transaction response.

func (*IntegrationTestSuite) MintERC20 

func (is *IntegrationTestSuite) MintERC20(callType CallType, contractData ContractsData, receiver common.Address, amount *big.Int) error

MintERC20 is a helper function to mint tokens on the ERC20 contract.

NOTE: we are checking that there was a Transfer event emitted (which happens on minting).

func (*IntegrationTestSuite) SetupTest 

func (is *IntegrationTestSuite) SetupTest()

type PrecompileTestSuite 

type PrecompileTestSuite struct {
	suite.Suite
	// contains filtered or unexported fields
}

PrecompileTestSuite is the implementation of the TestSuite interface for ERC20 precompile unit tests.

func NewPrecompileTestSuite 

func NewPrecompileTestSuite(create network.CreateEvmApp, options ...network.ConfigOption) *PrecompileTestSuite

func (*PrecompileTestSuite) SetupTest 

func (s *PrecompileTestSuite) SetupTest()

func (*PrecompileTestSuite) TestAllowance 

func (s *PrecompileTestSuite) TestAllowance()

func (*PrecompileTestSuite) TestApprove 

func (s *PrecompileTestSuite) TestApprove()

func (*PrecompileTestSuite) TestBalanceOf 

func (s *PrecompileTestSuite) TestBalanceOf()

func (*PrecompileTestSuite) TestDecimals 

func (s *PrecompileTestSuite) TestDecimals()

func (*PrecompileTestSuite) TestEmitApprovalEvent 

func (s *PrecompileTestSuite) TestEmitApprovalEvent()

func (*PrecompileTestSuite) TestEmitTransferEvent 

func (s *PrecompileTestSuite) TestEmitTransferEvent()

func (*PrecompileTestSuite) TestIsTransaction 

func (s *PrecompileTestSuite) TestIsTransaction()

func (*PrecompileTestSuite) TestNameSymbol 

func (s *PrecompileTestSuite) TestNameSymbol()

TestNameSymbolDecimals tests the Name and Symbol methods of the ERC20 precompile.

NOTE: we test both methods in the same test because they need the same testcases and the same setup.

func (*PrecompileTestSuite) TestParseAllowanceArgs 

func (s *PrecompileTestSuite) TestParseAllowanceArgs()

func (*PrecompileTestSuite) TestParseApproveArgs 

func (s *PrecompileTestSuite) TestParseApproveArgs()

func (*PrecompileTestSuite) TestParseBalanceOfArgs
