Running Tests

The testing scripts require Python 3.6+, web3.py 4.0.0+, py-solc 2.1.0+, and eth-utils 1.0.0+. To install these dependencies, ensure that python is up to date and run:

pip3 install -r requirements.txt

In addition solc 0.4.24+ must be installed. The test suite uses ganache 6.1.0+ for execution speed, state snapshots, and time fast-forwarding. It can be installed from the node package manager with:

npm install ganache-cli

Run the test suite as follows:

python3 run_tests.py
