Installing for local development

Follow the steps to clone the repo for you to make changes to this project.

  1. Clone the repo
git clone https://github.com/vyperlang/titanoboa
cd titanoboa
  1. Setup virtual environment and install dependencies

You can learn more about activating and deactivating virtual environments here.

python -m venv venv
source venv/bin/activate
# Install dev requirements
pip install -r dev-requirements.txt
# Install prod requirements (in the pyproject.tom)
pip install .

Note: When you delete your terminal/shell, you will need to reactivate this virtual environment again each time. To exit this python virtual environment, type deactivate

  1. Create a new branch
git checkout -b <branch_name>

And start making your changes! Once you're done, you can commit your changes and push them to your forked repo.

git commit -a
git push <your_forked_github>
  1. Run the linter
make lint

Running Tests

Once you have your environment setup, you can run the tests to make sure everything is working as expected. You'll need to have your virtual environment activated to run the tests.

Unit tests

Run the following:

pytest tests/unitary -x

This will skip the integration tests, which need extra "stuff".

Integration tests

Once you have setup your virtual environment, to run integration tests, you'll need to add environment variables.

You can see the .env.unsafe.example for environment variables you'll want to use.

MAINNET_ENDPOINT=<eth_mainnet_rpc_url>
SEPOLIA_ENDPOINT=<sepolia_rpc_url>
SEPOLIA_PKEY=<sepolia_private_key> # DO NOT USE A KEY ASSSOCIATED WITH REAL FUNDS

You can optionally copy .env.unsafe.example and create a new file called .env.unsafe file and run the following command to load the environment variables.

source .env.unsafe

Then, you can just run:

pytest tests/integration/ -x
