430 |
-- generate 500 opcodes times the number of defined opcodes, which |

431 |
-- then we pass in bulk to Python. The drawbacks to this method are |

432 |
-- two fold: we cannot control the number of generated opcodes, since |

433 |
-- HUnit assertions don't get access to the test options, and for the |

434 |
-- same reason we can't run a repeatable seed. We should probably find |

435 |
-- a better way to do this, for example by having a |

436 |
-- separately-launched Python process (if not running the tests would |

437 |
