准备工作比较多，以下都是在ubuntu18环境下
1、编译Testeth
最好参考2019-04-24 使用Testeth跑以太坊测试集
确保基本测试可以通过
代码语言：javascript复制git clone --recursive https://github.com/ethereum/aleth.git
cd aleth
mkdir build; cd build # Create a build directory.
cmake .. # Configure the project.
cmake --build . # Build all default targets.2、编译hera
可以参考2018-11-26 ewasm在以太坊私有链测试
代码语言：javascript复制cd ../../
git clone https://github.com/ewasm/hera --recursive
cd hera
mkdir build && cd build
cmake .. -DBUILD_SHARED_LIBS=ON
cmake --build .然后把动态库复制到testeth的目录下
代码语言：javascript复制cp src/libhera.so ../../aleth/build/test/.3、拉取ewasm测试用例
代码语言：javascript复制cd ../../
git clone https://github.com/ewasm/tests.git然后复制两个目录到testeth的目录下
代码语言：javascript复制cp tests/GeneralStateTests/stEWASMTests/* aleth/test/jsontests/GeneralStateTests/stEWASMTests/.
cp tests/src/GeneralStateTestsFiller/stEWASMTests/* aleth/test/jsontests/src/GeneralStateTestsFiller/stEWASMTests/.4、执行测试集
代码语言：javascript复制cd aleth/build/test/
./testeth -t GeneralStateTests/stEWASMTests -- --vm ./libhera.so --singlenet "Byzantium"测试单个用例：
代码语言：javascript复制./testeth -t GeneralStateTests/stEWASMTests -- --vm ./libhera.so --singletest callCode --singlenet "Byzantium"显示结果：
代码语言：javascript复制[2019-04-26 16:21:04.623418] [0x00007fc85b02fb00] [info] Loaded EVMC module: hera 0.2.3-alpha.0-3 commit.6fc7cb40 (./libhera.so)

参考# Debugging Ethereum Reference Tests
代码语言：javascript复制cd aleth/build
rm -rfd *
cmake .. -DVMTRACE=1
make
cd build/test
./testeth -t GeneralStateTests/stEWASMTests -- --vm ./libhera.so --singletest createCode --singlenet "Byzantium" --verbosity 3 --vmtrace --statediff显示：
