test_invalid_max_blobs_per_tx()

Documentation for tests/osaka/eip7594_peerdas/test_max_blob_per_tx.py::test_invalid_max_blobs_per_tx@2867859a.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/osaka/eip7594_peerdas/test_max_blob_per_tx.py::test_invalid_max_blobs_per_tx --fork Amsterdam

Test that transactions exceeding MAX_BLOBS_PER_TX are rejected. Verifies that individual transactions cannot contain more than the maximum allowed number of blobs per transaction, even if the total would be within the block limit.
