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.
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
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.
Run make test from the root of the spec repository.
From within the pyspec folder:
Install dependencies:
python3 -m venv venv
. venv/bin/activate
pip3 install -r requirements-testing.txtNote: 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 eth2spec
Note the package-name, this is to locate the tests.
Contributions are welcome, but consider implementing your idea as part of the spec itself first. The pyspec is not a replacement.
Same as the spec itself, see LICENSE file in spec repository root.
