Benchmark Tests

Contains consolidated blockchain tests that can be used for benchmarking, as well as the original state_tests, blockchain_tests and blockchain_tests_engine.

The included file fixtures_benchmark.tar.gz contains all different benchmark test files for multiple gas limits: 1M, 10M, 30M, 45M, 60M, 90M, and 120M.

To select a test for a given gas limit, the IDs of the tests have been expanded to contain benchmark-gas-value_XM, where X can be any of the aforementioned values (e.g. benchmark-gas-value_1M, benchmark-gas-value_10M, and so on).

For more information on the new format see Blockchain Engine X Tests in the EEST documentation.

Forks Included

• Cancun
• Prague

Note: Osaka is still not supported for benchmarks, but will be in a future release.
