pip install pytest-ethereum
If you would like to hack on pytest-ethereum, please check out the Ethereum Development Tactical Manual for information on how we do:
You can set up your dev environment with:
git clone git@github.com:ethereum/pytest-ethereum.git
cd pytest-ethereum
virtualenv -p python3 venv
. venv/bin/activate
pip install -e .[dev]
During development, you might like to have tests run on every file save.
Show flake8 errors on file change:
# Test flake8
when-changed -v -s -r -1 pytest_ethereum/ tests/ -c "clear; flake8 pytest_ethereum tests && echo 'flake8 success' || echo 'error'"
Run multi-process tests in one command, but without color:
# in the project root:
pytest --numprocesses=4 --looponfail --maxfail=1
# the same thing, succinctly:
pytest -n 4 -f --maxfail=1
Run in one thread, with color and desktop notifications:
cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on pytest-ethereum failed'" ../tests ../pytest_ethereum
For Debian-like systems:
apt install pandoc
To release a new version:
make release bump=$$VERSION_PART_TO_BUMP$$
The version format for this repo is {major}.{minor}.{patch}
for stable, and
{major}.{minor}.{patch}-{stage}.{devnum}
for unstable (stage
can be alpha or beta).
To issue the next version in line, specify which part to bump,
like make release bump=minor
or make release bump=devnum
.
If you are in a beta version, make release bump=stage
will switch to a stable.
To issue an unstable version when the current version is stable, specify the
new version explicitly, like make release bump="--new-version 4.0.0-alpha.1 devnum"
