# Ethereum Test RPC server
[](https://gitter.im/pipermerriam/eth-testrpc?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
## Ethereum Test RPC
Limited RPC client intended for use with automated testing. Uses
[pythereum](https://github.com/ethereum/pyethereum) 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`
* Tag the release.
```
git tag -s -m "X.X.X Release" vX.X.X
git push --tags
```
* Go make the release on github for the tag you just pushed
* Build and push release to PyPI
```
make release
```
