test_insufficient_balance_blob_tx()

Documentation for tests/cancun/eip4844_blobs/test_blob_txs.py::test_insufficient_balance_blob_tx@20373115.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_blob_txs.py::test_insufficient_balance_blob_tx --fork Amsterdam

Reject blocks where user cannot afford the blob gas specified (but max_fee_per_gas would be enough for current block).

• Transactions with max fee equal or higher than current block base fee
• Transactions with and without priority fee
• Transactions with and without value
• Transactions with and without calldata
• Transactions with max fee per blob gas lower or higher than the priority fee
