Run the test filler to generate consensus layer test fixtures.
Default Usage
uv run fill --fork=Lstar --clean -n auto
Options
Pass additional arguments after --:
/fill -- --scheme=prod- Use production signature scheme (slower)/fill -- --fork=<other>- Generate for a different fork/fill -- path/to/test.py- Generate fixtures for specific test file
What It Does
- Discovers tests in
tests/consensus/ - Executes spec tests to generate fixtures
- Outputs JSON fixtures to
fixtures/consensus/
The just fill-ci recipe wraps the same command for CI; contributors should
invoke uv run fill directly so flags like --fork and --clean stay visible.
