ETH 2.0 PySpec
The Python executable spec is built from the ETH 2.0 specification, complemented with the necessary helper functions for hashing, BLS, and more.
With this executable spec, test-generators can easily create test-vectors for client implementations, and the spec itself can be verified to be consistent and coherent, through sanity tests implemented with pytest.
Building
All the dynamic parts of the spec can be build at once with make pyspec.
Alternatively, you can build a sub-set of the pyspec: make phase0.
Or, to build a single file, specify the path, e.g. make test_libs/pyspec/eth2spec/phase0/spec.py
Py-tests
After building, you can install the dependencies for running the pyspec tests with make install_test
These tests are not intended for client-consumption. These tests are sanity tests, to verify if the spec itself is consistent.
How to run tests
Automated
Run make test from the root of the spec repository.
Manual
From within the pyspec folder:
Install dependencies:
python3 -m venv venv
. venv/bin/activate
pip3 install -e .[dev]
Note: make sure to run make -B pyspec from the root of the specs repository,
to build the parts of the pyspec module derived from the markdown specs.
The -B flag may be helpful to force-overwrite the pyspec output after you made a change to the markdown source files.
Run the tests:
pytest --config=minimal
Contributing
Contributions are welcome, but consider implementing your idea as part of the spec itself first. The pyspec is not a replacement.
License
Same as the spec itself, see LICENSE file in spec repository root.
