EOS_EVM Test Tool

Description

This project provides a light, standalone eos-vm testing environment, which can be used for contracts testing without deploying on a testnet. For now this tool is designated for the challenge, to execute evm transactions. See 1 for more deails.

Dependency

1. jsoncpp

Linux:

sudo apt-get install libjsoncpp-dev

Mac OS:

brew install jsoncpp

2. OpenSSL

Linux:

sudo apt-get install libssl-dev

Mac OS:

brew install openssl

3. eos-vm

4. evmc

5. secp256k1

Usage

Building from source

1. Clone the repo and create a build directory:

git clone --recursive https://github.com/eosiosg/vm-test
cd vm-test
mkdir build
cd build

2. Build the source:

cmake ..
cmake --build . -- -j

3. Include the library in other evmc compatible test schemes:

Linux:

lib/libeosevm.so  

Mac OS:`

lib/libeosevm.dylib

example: using testeth from aleth: testeth -t VMTests -- --all --vm /path_to_build/lib/libeosevm.dylib

4. Run supplementary tests:

test/EOSEVMTest  

supplementary tests cover cases that require states check, which are likely to fail on some eth tests. Therefore, these cases were integrated explicitly in this project.
5. Run custom eos contract tests: refer to test/eosio_token_test.cpp to write custom tests.
