test_self_destructing_initcode_create_tx()

Documentation for tests/cancun/eip6780_selfdestruct/test_selfdestruct.py::test_self_destructing_initcode_create_tx@b314d18e.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip6780_selfdestruct/test_selfdestruct.py::test_self_destructing_initcode_create_tx --fork Amsterdam

Use a Create Transaction to execute a self-destructing initcode.

Behavior should be the same before and after EIP-6780.

Test using

• Different initial balances for the self-destructing contract
• Different transaction value amounts
