You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fevm_test.go
    path of file: ./repos/lotus/itests
    
    the code of the file until where you have to start completion: package itests

import (
	"bytes"
	"context"

    
func TestFEVMDeployWithValue(t *testing.T) {
	ctx, cancel, client := kit.SetupFEVMTest(t)
	defer cancel()

	//testValue is the amount sent when the contract is created
	//at the end we check that the new contract has a balance of testValue
	testValue := big.NewInt(20)

	// deploy DeployValueTest which creates NewContract
	// testValue is sent to DeployValueTest and that amount is
	// also sent to NewContract
	filenameActor := "contracts/DeployValueTest.hex"
	fromAddr, idAddr := client.EVM().DeployContractFromFilenameWithValue(ctx, filenameActor, testValue)

	//call getNewContractBalance to find the value of NewContract
	ret, _, err := client.EVM().InvokeContractByFuncName(ctx, fromAddr, idAddr, "getNewContractBalance()", []byte{})
	require.NoError(t, err)

	contractBalance, err := decodeOutputToUint64(ret)
	require.NoError(t, err)

	//require balance of NewContract is testValue
	require.Equal(t, testValue.Uint64(), contractBalance)
}
