Ethereum Consensus Tests

Common tests for all clients to test against. Test execution tool: https://github.com/ethereum/retesteth

Test Formats

Maintained tests:

/BasicTests
/BlockchainTests
/GeneralStateTests
/TransactionTests
/RLPTest
/src

See descriptions of the different test formats in the official documentation at http://ethereum-tests.readthedocs.io/.

Note:
The format of BlockchainTests recently changed with the introduction of a new field sealEngine (values: NoProof | Ethash), see related JSON Schema change or BlockchainTest format docs for reference.

This means that you can skip PoW validation for NoProof tests but also has the consequence that it is not possible to rely on/check PoW related block parameters for these tests any more.

Clients using the library

The following clients make use of the tests from this library. You can use these implementations for inspiration on how to integrate. If your client is missing, please submit a PR (requirement: at least some minimal test documentation)!

Using the Tests

We do versioned tag releases for tests and you should aim to run your client libraries against the latest repository snapshot tagged.

Generally the develop branch in ethereum/tests is always meant to be stable and you should be able to run your test against.

If you want to follow up with current tasks and what is currently in the works, have a look at the issues

Currently the C++ Aleth client is the reference client for generating tests. Have a look at issues and PRs tagged with testeth to get an idea what is currently being worked on regarding the test generation process.
