  /*
   * Pass some system properties provided on the gradle command line to test executions for
   * convenience.
   *
   * The properties passed are:
   * - 'test.ethereum.include': allows to run a single Ethereum reference tests. For instance,
   *   running a single general state test can be done with:
   *    ./gradlew :ethereum:tech.pegasys.pantheon.ethereum.vm:test -Dtest.single=GeneralStateTest -Dtest.ethereum.include=callcodecallcallcode_101-Frontier
   *   The meaning being that will be run only the tests for which the value passed as "include"
   *   (which can be a java pattern) matches parts of the test name. Knowing that tests names for
   *   reference tests are of the form:
   *     <name>(-<milestone>([<variant>])?)?
   *   where <name> is the test name as defined in the json file (usually the name of the json file
   *   as well), <milestone> is the Ethereum milestone tested (not all test use it) and <variant>
   *   is only use in some general state tests where for the same json file and same milestone,
   *   multiple variant of that test are run. The variant is a simple number.
   * - 'test.ethereum.state.eip': for general state tests, allows to only run tests for the
   *   milestone specified by this value. So for instance,
   *    ./gradlew :ethereum:tech.pegasys.pantheon.ethereum.vm:test -Dtest.single=GeneralStateTest -Dtest.ethereum.state.eip=Frontier
   *   only run general state tests for Frontier. Note that this behavior could be achieved as well
   *   with the 'include' option above since it is a pattern, but this is a slightly more convenient
   *   option.
   * - 'root.log.level' and 'evm.log.level': allow to control the log level used during the tests.
