test_block_full_of_ether_transfers()

Documentation for tests/benchmark/test_worst_blocks.py::test_block_full_of_ether_transfers@0f7c73a7.

Generate fixtures for these test cases for Prague with:

fill -v tests/benchmark/test_worst_blocks.py::test_block_full_of_ether_transfers --fork Prague

Single test for ether transfer scenarios.

Scenarios: - a_to_a: one sender → one sender - a_to_b: one sender → one receiver - diff_acc_to_b: multiple senders → one receiver - a_to_diff_acc: one sender → multiple receivers - diff_acc_to_diff_acc: multiple senders → multiple receivers
