### Ethereum reference tests

On top of the project proper unit tests, specific unit tests are provided to
run the Ethereum reference tests available at https://github.com/ethereum/tests
and described at http://ethereum-tests.readthedocs.io/en/latest/. Those are run
as part of the unit test suite as described above, but for debugging, it is
often convenient to run only a subset of those tests, for which a few convenience
as provided. For instance, one can run only "Frontier" general state tests with
```
./gradlew :ethereum:net.consensys.pantheon.ethereum.vm:referenceTest -Dtest.single=GeneralStateTest -Dtest.ethereum.state.eip=Frontier
```
or only the tests that match a particular pattern with something like:
```
gradle :ethereum:net.consensys.pantheon.ethereum.vm:test -Dtest.single=GeneralStateTest -Dtest.ethereum.include='^CALLCODE.*-Frontier'
```
Please see the comment on the `test` target in the top level `build.gradle`
file for more details.
