test_slotnum_mainnet()

Documentation for tests/amsterdam/eip7843_slotnum/test_eip_mainnet.py::test_slotnum_mainnet@ffe48572.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7843_slotnum/test_eip_mainnet.py::test_slotnum_mainnet --fork Amsterdam

Test that SLOTNUM executes and pushes one stack item.

Asserts on POP(SLOTNUM) followed by a storage write rather than on the slot value itself, so the test remains valid when execute-ed against a live network, where the slot number is whatever the consensus layer transmits and cannot be controlled by the test.
