Fixes ethereum#1020 Implements minimize-tests integration to dramatically reduce json_infra test execution time from hours to minutes while maintaining full coverage. Changes: - Added minimize-tests dependency to pyproject.toml test group - Created generate_minimal_tests.py script to compute minimal test set - Added tox environment 'json_infra_min' to run minimal tests with coverage enforcement - Added tox environment 'json_infra_generate' to regenerate minimal test list - Created minimal_tests.txt placeholder for generated test IDs How it works: 1. Run all json_infra tests with --cov-context=test to track coverage per test 2. Use minimize-tests tool to solve set cover problem (find minimum tests covering all lines) 3. Run only the minimal test set with --cov-fail-under to enforce coverage threshold 4. Regenerate when coverage drops or code changes significantly Usage: tox -e json_infra_min # Run minimal tests (fast) tox -e json_infra_generate # Regenerate minimal test list tox -e json_infra # Run full suite (slow) Expected impact: 20-50x speedup for json_infra tests while maintaining same code coverage as the full test suite.

🗒️ Description
Implements the
minimize-testsapproach to dramatically reducejson_infratest execution time from hours to minutes while maintaining full code coverage.This PR adds infrastructure to generate and run a minimal subset of
json_infratests using set cover optimization. Thejson_infratests verify that EELS can execute filled JSON fixtures, so we don't need to run all fixtures.Key additions:
tox -e json_infra_generate: Generates minimal test list using minimize-tests tooltox -e json_infra_min: Runs minimal test set with coverage enforcement (fast)tox -e json_infra: Unchanged (full suite)🔗 Related Issues or PRs
Closes #1020
