test_invalid_gas_g2msm()

Documentation for tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py::test_invalid_gas_g2msm@20373115.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/prague/eip2537_bls_12_381_precompiles/test_bls12_variable_length_input_contracts.py::test_invalid_gas_g2msm --fork Amsterdam

Test the BLS12_G2MSM discount gas table in full, by expecting the call to fail for all possible input lengths because the appropriate amount of gas is not provided.

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