Used for testing all maner of Ethereum JSON-RPC interactions.

Ethereum Test RPC server

Ethereum Test RPC

Limited RPC client intended for use with automated testing. Uses pythereum to run an Ethereum client behind the scenes without the need for mining or networking. The result is an Ethereum client that provides instant results and quick feedback during development.

Install

Installing is easy, through pip:

$ pip install eth-testrpc

Or, to upgrade:

pip install eth-testrpc --upgrade

Or, to install with gevent threads

pip install eth-testrpc[gevent]

And then set the environment variable TESTRPC_THREADING_BACKEND=gevent

Run

Installing through pip will make the testrpc-py command available on your machine:

$ testrpc

This will run testrpc on localhost:8545. You can pass through a different port (-p, --port) or domain (-d, --domain).

Implemented methods

The RPC methods currently implemented are:

• eth_coinbase
• eth_accounts
• eth_gasPrice
• eth_blockNumber
• eth_sendTransaction
• eth_sendRawTransaction
• eth_call
• eth_getCompilers
• eth_compileSolidity
• eth_getCode (only supports block number “latest”)
• eth_getBalance
• eth_getTransactionCount
• eth_getTransactionByHash
• eth_getTransactionReceipt
• eth_newBlockFilter (temporarily removed until implemented in underlying library)
• eth_newFilter (temporarily removed until implemented in underlying library)
• eth_getFilterChanges (temporarily removed until implemented in underlying library)
• eth_uninstallFilter (temporarily removed until implemented in underlying library)
• eth_protocolVersion ( see rpc_configure)
• eth_syncing ( see rpc_configure)
• eth_mining ( see rpc_configure)
• web3_sha3
• web3_clientVersion
• net_version (see rpc_configure)
• net_listening (see rpc_configure)
• net_peerCount (see rpc_configure)

There’s also special non-standard methods that aren’t included within the original RPC specification:

• evm_reset : No params, no return value.
• evm_snapshot : No params. Returns the integer id of the snapshot created.
• evm_revert : One optional param. Reverts to the snapshot id passed, or the latest snapshot.

When calling evm_reset, the testrpc will revert the state of its internal chain back to the genesis block and it will act as if no processing of transactions has taken place. Similarly, you can use evm_snapshot and evm_revert methods to save and restore the evm state as desired. Example use cases for these methods are as follows:

• evm_reset : Run once at the beginning of your test suite.
• evm_snapshot : Run at the beginning of each test, snapshotting the state of the evm.
• evm_revert : Run at the end of each test, reverting back to a known clean state.

TestRPC also exposes the evm_mine method for advancing the test evm by some number of blocks.

• evm_mine : Optionally supply an integer for the number of blocks to mine. Default is 1 block. No return value.

TestRPC exposes the testing_timeTravel method for fast-forwarding to a future timestamp.

• testing_timeTravel : Takes an integer timestamp that must be greater than the timestamp of the current latest block.

TestRPC exposes the rpc_configure method which can be used to modify the static values returned by the following endpoints.

• eth_protocolVersion (default 63)
• eth_syncing (default False)
• eth_mining (default True)
• net_version (default 1)
• net_listening (default False)
• net_peerCount (default 0)
• homestead_block_number (default 0)
• dao_fork_block_number (default 0)
• anti_dos_fork_block_number (default 0)
• clearing_fork_block_number (default 0)

The rpc_configure takes two parameters.

• key: string representing the rpc method on which you want to change the return value.
• value: the value that should be returned by the endpoint.

The homestead, dao, anti_dos and clearing fork configurations determine which block number the respective fork rules should come into effect. All default to 0.

TestRPC uses a default gas limit of 4000000. To change this set the environment variable TESTRPC_GAS_LIMIT to the desired value.

Releasing a new version (for eth-testrpc developers)

• Bump version number in setup.py
• Add entry to CHANGES.txt

eth-testrpc's Issues

eth_getTransactionReceipt logs

as of testrpc 0.1.17 logs are missing from eth_getTransactionReceipt

mark as deprecated?

README needs to mention solc

The README should mention that eth-testrpc depends on solc to compile Solidity contracts. These are the instructions to install solc: https://github.com/ethereum/cpp-ethereum/wiki/Installing-clients .

eth-testrpc 1.3.5 has requirement rlp<=0.6.0,>=0.4.7 but you'll have rlp 1.0.3

• versions: web3 4.7.2, testrpc 1.3.5, python 3.5.3
• OS: linux

What was wrong?

virtualenv -p python3 env/py3eth
source env/py3eth/bin/activate

pip3 install rlp eth-testrpc

results in a red line

...
eth-testrpc 1.3.5 has requirement rlp<=0.6.0,>=0.4.7, but you'll have rlp 1.0.3 which is incompatible.

Don't know how to run it anymore.

Error: Method net_listening not supported.

Greetings,

I'm running testrpc which seems to work fine.

I go to http://meteor-dapp-cosmo.meteor.com/ and I plug it in to localhost:8545 and I get this error:

Web3 Connected! HTTPProvider -> http://localhost:8545
Error: Method net_listening not supported.

Invalid block timestamp

• eth-testrpc Version 1.3.3
• py-geth Version: 2.0.0
• go-ethereum Version: 1.7.3
• Python Version: 3.6.4
• OS: linux

What was wrong?

block.timestamp in solidity returns wrong time, somewhere between 1400000000 and 1500000000.

There is similar old issue: #25

Support for Ethereum 2.x

There is something that prevents support for ethereum==2.x ?

Thanks in advance 🚀

Filters from "latest" to "latest" always return empty list

Package versions:
eth-testrpc: 0.8.7
ethereum-tester-client: 1.2.5
geth: 1.5.3, 1.5.4

What was wrong?

When using filters, if filter has {"fromBlock": "latest", "toBlock": "latest"} (to retrieve logs from the most recently mined transaction), testrpc returns an empty list, while geth returns a correct log.
A minimal example which shows the current behaviour:

import pytest
from eth_tester_client.utils import encode_address
from ethereum import tester


@pytest.fixture(params=[
    'testrpc',
    'temp',
])
def chain(project, request):
    with project.get_chain(request.param) as chain:
        if request.param == 'temp':
            address = chain.web3.personal.importRawKey(tester.keys[0], "")
            assert address == encode_address(tester.accounts[0])
            chain.web3.personal.unlockAccount(address, "", duration=0)
            chain.wait.for_unlock(address)
        yield chain


def deploy(chain, contract_name):
    contract_factory = chain.get_contract_factory(contract_name)
    deploy_txn_hash = contract_factory.deploy()
    deploy_address = chain.wait.for_contract_address(deploy_txn_hash, timeout=120)
    return contract_factory(address=deploy_address)


def test_latest_logs(chain):
    contract = deploy(chain, 'TestContract')
    event_filter = contract.pastEvents('TestEvent', {"fromBlock": "latest",
                                                     "toBlock": "latest"})
    txn_hash = contract.transact().do_action(1234)
    chain.wait.for_receipt(txn_hash)
    event_logs = event_filter.get()
    assert event_logs
    event_logs = filter(lambda log: log["transactionHash"] == txn_hash, event_logs)
    assert len([e["args"] for e in event_logs]) > 0

and the TestContract.sol:

contract TestContract {
    event TestEvent(uint value);
    function do_action(uint value){
        TestEvent(value);
    }
}

When running, I get:

____ test_latest_logs[testrpc] ____

chain = <populus.chain.TestRPCChain object at 0x7fa413aa0f50>

    def test_latest_logs(chain):
        contract = deploy(chain, 'TestContract')
        event_filter = contract.pastEvents('TestEvent', {"fromBlock": "latest",
                                                         "toBlock": "latest"})
        txn_hash = contract.transact().do_action(1234)
        chain.wait.for_receipt(txn_hash)
        event_logs = event_filter.get()

truffle deploy throws error even when deploying an empty contract

I got "Error: The contract code couldn't be stored, please check your gas amount." when deploy an empty contract against testrpc

testrpc.py", line 294, in eth_compileSolidity

Hi,

I get an error in testrpc.py performing the truffle deploy:

Docker Support?

• py-geth Version: x.x.x
• go-ethereum Version: x.x.x
• Python Version: x.x.x
• OS: osx/linux/win

What was wrong?

Nothing wrong, but it would be convenient to have a docker container for easier developer env setup. For example, I am running web3.py locally but I need a testrpc running to test with. Since I'm also running web3.py in docker, I could simply add a eth-testrpc docker image to the docker-compose.yml file and the web3.py docker container would have access to the test port 8545.

ok I'm trying to run my tests on a machine I used 6 months ago, so I might have messed up with deps, but this seems so weird to me that nobody got this error yet, it seems like it's downstream in ethereum/tester.py
while I can definitely understand that the print should have parenthesis for python3, I don't know how to fix in my install,
that serpent.py file, where does it come from ?

Out of gas error when using constructors

The following contract

contract TestContract {

    address public creator;
    address[] public array1;
    address[] public array2;

    function TestContract(bytes2 someStuff,
              bytes32 moreStuff,
              address[] _array1,
              bytes32[] _array2,
              uint _additionalStuff) {

    creator = msg.sender;             
    array1 = _array1;

    }    
}

with the following test in truffle:

contract 'TestContract', (accounts) ->

  it "should construct and populate ", (done) ->
    stuff = "0x1220"
    stuff2 = "0x1c8aff950685c2ed4bc3174f3472287b56d9517b9c948127319a09a7a36deac8"
    array2 = ["0x416c696365", "0x426f62"]
    array1 = [accounts[0], accounts[1]]
    num = 2
    TestContract.new(stuff, stuff2, array1, array2, num, {gasLimit: 3000000}).then (ctr) ->
      ctr.creator.call(0).then (creator) ->
        assert.strictEqual(creator, accounts[0], "Wrong creator!")
        done()
      .catch (err) ->
        done(err)

gives out-of-gas error in the testrpc. If any of the inputs are commented out it succeeds and it also succeeds if the line array1 = _array1; is commented out. 3000000 gasLimit should be enough here I think.

debug_traceTransaction integration

{"jsonrpc":"2.0","id":331,"method":"debug_traceTransaction","params":["0x9cda11aa741ebc2b737a1844e33d82b5a40e05f442c2f84667445c96dca93a9b",{"disableStorage":true,"disableMemory":false,"disableStack":false,"fullStorage":false}]}

Answer: Method not found

It would be really awesome if with the testrpc-py could we debug the transactions using remix!

log0 in a contract's constructor fails if the creator has not sent a transaction.

Take the following code on a FRESH testrpc:

logtest = "contract logtest { function logtest() { log0(\"A\"); } }"
compiled = web3.eth.compile.solidity(logtest)
web3.eth.sendTransaction(compiled.logtest.code)

It will complain

Error: Server error:   File "/home/xxx/.virtualenvs/truffle/local/lib/python2.7/site-packages/testrpc/testrpc.py", line 169, in __call__ | AttributeError: state instance has no attribute 'last_tx'

However, if you send a non-contract transaction before that, it will work.

Adding more accounts to testrpc-py

• OS: Linux Lubuntu 16.04

I am using testrpc-py for research purposes, and in that regard it would be perfect to add more accounts. In the js testrpc this is simply done by initialise testrpc --accounts "number"
However, I have not found a simple manner of increasing the amount for testrpc-py. Is there a command for this, or could I implement it another way?

eth-testrpc doesn't install cleanly from PyPI

Installing eth-testrpc from PyPI is not clean. Despite the fact that jsonrpclib and ethereum are listed as dependencies in setup.py, they need to be installed manually before running pip install eth-testrpc.

To reproduce this issue, make sure to use an empty virtual env.

New release on PyPi

Can you make a new release on PyPi? Quite a lot of changes has happened since v0.8.7. Would be nice if that could be included in a new release. If the code base is ready to be release that is, of course.

This code gives a TransactionFailed. If I change value to 0, it works, but then I can't actually have contracts use send/transfer. It also doesn't work to do a send transaction with the to being the contractAddress.

from testrpc.client import EthTesterClient
from solc import *
from solc.exceptions import SolcError

c = EthTesterClient()

ac = sorted(c.get_accounts())

contract = """
contract c {

function f() returns (int) {
  return 10;
}

}
"""

bin = compile_source(contract,optimize=True).values()[0]['bin']

txnHash = c.send_transaction(_from = ac[0], data = bytes(bin), value=1000)

txnReceipt = c.get_transaction_receipt(txnHash)
contractAddress = txnReceipt['contractAddress']

print (contractAddress), c.get_balance(contractAddress)

Cannot run: import error (set_logging_level)

• Python Version: 2.7.11+
• OS: linux
• pyethereum version: 1.3.6
• eth-testrpc version: 0.3.2

What was wrong?

When trying to run testrpc (without any additional arguments), I get the following error:

⇒ testrpc                          
Traceback (most recent call last):

Change JSON-RPC libraries?

I'm trying to use Test RPC in conjunction with my gulp-ethertest tool, but it looks like jsonrpclib is pretty easily brought to its knees by simple test cases. In particular, jsonrpclib seems to have a request-prioritization problem that leads to early requests for filter logs to be drowned out by block filter watchers. In a private testing environment, requests would ideally be handled in a more-or-less-FIFO order. (Which is to be expected in a multi-threaded server, of course, but parallel request processing is really not a positive in this case.)

Alternatively, introducing an optional delay between mining blocks might help.

Can't install eth-testrpc

• Python Version: 2.7.6
• OS: linuxmint 17.03

What was wrong?

Feature: Ability to persist blockchains across runs.

It would be very useful to be able to save/snapshot the blockchain across runs via some sort of save-to-file, load-from-file method.

No Byzantium-like `status` field present in receipts

What was wrong?

The receipts generated by eth-testrpc still do not contain the status field introduced by Byzantium. This makes it impossible to test code relying on this field.

Cute Animal Picture

After i execute the cmd "testrpc ", the console echos "<generator object main at 0x7feae0364230>"

i can't find the process named testrpc ,and i can't find link which is listening 8545 port.

eth-testrpc installation errors (e.g. python)

Hi,

the installation of eth-testrpc raises several errors. Interessting is the python too:

http://pastebin.com/yKrXXMZa

The installation was done with "pip install eth-testrpc"
It seems that the installation uses a python3 library although python2.7 is needed.
If you see in the log, the library python2.7 is used in most part of the installation, but there is an error concerning the utils_py3.py library, between others

Regards
SkyDog

The `"earliest"` block identifier should return block #1

What was wrong?

Currently if you call eth_getBlockByNumber("earliest") you will get the genesis block which is block number 0. Based on the behavior of geth and parity, this should be returning block number 1.

Does this work with Python 3.5?

Hello Friends:

Does this work with Python 3.5? Sometimes the pip3 install of a package will succeed even though it is not supported. :)

Thank you!

Deprecate the `ethereum-tester-client` and vendor it into this repository.

It's dumb that these are separate projects. Lets move all of ethereum-tester-client into this codebase.

Implement `eth_sign`

The eth_sign interface hasn't been implemented.

• Don't add the secp256k1 dependency.
• Have the eth_sign function check whether secp256k1 is available and if so, execute the signing. If not, return a user friendly error message instructing them to install the dependency.

Request to implement block filter and pending transaction filter

• Python Version: 3.6
• OS: Ubuntu 17.10

Please finish implementing methods for block filter and pending transaction filter methods. Currently they are throwing NotImplementedError.

Details:
eth-testrpc/rpc.py line number: 187
Method : eth_newBlockFilter

eth-testrpc/rpc.py line number: 191
Method : eth_newPendingTransactionFilter

You can't make `eth_call` requests from an address that's not one of the ones created for you.

Importing eth_testrpc causes gevent to break stdlib

Importing eth-testrpc implicitly creates a global EthTesterClient instance which has a call to gevent.spawn().

This hangs Python interpreter

https://github.com/pipermerriam/eth-testrpc/blob/master/testrpc/testrpc.py#L29

I recommend not to have implicit calls to gevent as they tend to break Python for other software, like web servers, debuggers or schedulers.

Bad date generated for Solidity's 'now'

When my Solidity contracts store a date with now, I later get a value like 1410973360 when I query that date. This is about a year in the past (the clock on my computer is fine). Perhaps this is a pyethereum issue?

Make testrpc a module

Hi,
I think something is missing in the install instructions. I follow them and I got the error:

$ python testrpc.py
Traceback (most recent call last):

It happens only when metamask is connected

`sendTransaction` does not support `nonce` parameter

• py-geth Version: x.x.x
• go-ethereum Version: x.x.x
• Python Version: 3.6.2
• OS: osx

What was wrong?

When passing a custom nonce to web3.eth.sendTransaction, an _send_transaction() got an unexpected keyword argument 'nonce' exception is raised. It is probably because the:

    def _send_transaction(self, _from=None, to=None, gas=None, gas_price=None,
                          value=0, data=b''):

method does not have a nonce keyword argument.

If it is too complicated too implement it perfectly, maybe it should just compare the nonce passed with the next nonce available and just throw an exception if it's not equal...? I wanted to unit-test a piece of code which explicitly passes nonces in order to do some dynamic gas price manipulation, but I cannot because of the above :(

Cute Animal Picture

what is the time unit of the block timestamps in testrpc?

• versions: web3 4.7.2, testrpc 1.3.5, python 3.5.3
• OS: linux

What was wrong?

when I read
web3.eth.getBlock(blockNumber) ["timestamp"]
from two blocks
which were actually (i.e. I measured) produced at 38.8 seconds apart.

and then subtract these timestamps, I get a difference of 7945 units.

Why not 39, or 38800 or 38800000 ?
i.e. anything that remotely resembles {,milli,micro,nano}seconds.

Have a look:

I had hammered 1000 transactions at testrpc-py, which took 38.8 seconds to finish.

Cute Animal Picture

Different transaction hashes

tx_hash is differs from tx_data["hash"]

def eth_getTransactionReceipt(tx_hash):
    print "eth_getTransactionReceipt"

    global transaction_contract_addresses

    tx_data = eth_getTransactionByHash(tx_hash)
    block_data = eth_getBlockByNumber(tx_data["blockNumber"], False)

    return {
        "transactionHash": tx_data["hash"],

eth_sendTransaction invalid param gasPrice

When I run script that runs perfectly fine on geth/(js)testrpc eth-testrpc throws error with message _send_transaction() got an unexpected keyword argument 'gasPrice'.
gasPrice should be translated to internal gas_price.
