`test_invalid_block_blob_count()`¶

Documentation for tests/cancun/eip4844_blobs/test_blob_txs.py::test_invalid_block_blob_count@ffe48572.

Generate fixtures for these test cases for Bogota with:

fill -v tests/cancun/eip4844_blobs/test_blob_txs.py::test_invalid_block_blob_count --fork Bogota

Test all invalid blob combinations in a single block, where the sum of all blobs in a block is at MAX_BLOBS_PER_BLOCK + 1.

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