test_valid_blob_tx_combinations()

Documentation for tests/cancun/eip4844_blobs/test_blob_txs.py::test_valid_blob_tx_combinations@892e6d1e.

Generate fixtures for these test cases for Amsterdam with:

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

Test all valid blob combinations in a single block, assuming a given value of MAX_BLOBS_PER_BLOCK.

This assumes a block can include from 1 and up to MAX_BLOBS_PER_BLOCK transactions where all transactions contain at least 1 blob, and the sum of all blobs in a block is at most MAX_BLOBS_PER_BLOCK.

This test is parametrized with all valid blob transaction combinations for a given block, and therefore if value of MAX_BLOBS_PER_BLOCK changes, this test is automatically updated.
