Function NewForTesting

ethereum/ethash/ethash.go:512–518

NewForTesting creates a proof of work for use in unit tests. It uses a smaller DAG and cache size to keep test times low. DAG files are stored in a temporary directory. Nonces found by a testing instance are not verifiable with a regular-size cache.
