### Question:
TransactionValidationParams { public static TransactionValidationParams transactionSimulator() { return transactionSimulatorParams; } private  TransactionValidationParams(
      final boolean allowFutureNonce,
      final boolean checkOnchainPermissions,
      final boolean checkLocalPermissions); boolean isAllowFutureNonce(); boolean checkOnchainPermissions(); boolean checkLocalPermissions(); static TransactionValidationParams transactionSimulator(); static TransactionValidationParams processingBlock(); static TransactionValidationParams transactionPool(); static TransactionValidationParams mining(); static TransactionValidationParams blockReplay();  }### Answer:
@Test public void transactionSimulator() { final TransactionValidationParams params = TransactionValidationParams.transactionSimulator(); assertThat(params.isAllowFutureNonce()).isFalse(); assertThat(params.checkOnchainPermissions()).isFalse(); assertThat(params.checkLocalPermissions()).isFalse(); }
