test_invalid_gas_pairing()

Documentation for tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py::test_invalid_gas_pairing@0fdd974b.

Generate fixtures for these test cases for Osaka with:

fill -v tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py::test_invalid_gas_pairing --fork Osaka

Test the BLS12_PAIRING precompile, by expecting the call to fail for all possible input lengths (up to k == PAIRINGS_TO_TEST) because the appropriate amount of gas is not provided.

If any of the calls succeeds, the test will fail.
