### Question:
TransactionProcessor { @NotNull public PushTransactionResponse signAndBroadcast() throws TransactionSignAndBroadCastError { EosioTransactionSignatureRequest eosioTransactionSignatureRequest; try { eosioTransactionSignatureRequest = this.createSignatureRequest(); } catch (TransactionCreateSignatureRequestError transactionCreateSignatureRequestError) { throw new TransactionSignAndBroadCastError(transactionCreateSignatureRequestError); } try { this.getSignature(eosioTransactionSignatureRequest); } catch (TransactionGetSignatureError transactionGetSignatureError) { throw new TransactionSignAndBroadCastError(transactionGetSignatureError); } if (this.serializedTransaction == null || this.serializedTransaction.isEmpty()) { throw new TransactionSignAndBroadCastError( ErrorConstants.TRANSACTION_PROCESSOR_SIGN_BROADCAST_SERIALIZED_TRANSACTION_EMPTY); } if (this.signatures.isEmpty()) { throw new TransactionSignAndBroadCastError( ErrorConstants.TRANSACTION_PROCESSOR_SIGN_BROADCAST_SIGN_EMPTY); } PushTransactionRequest pushTransactionRequest = new PushTransactionRequest(this.signatures, 0, "", this.serializedTransaction); try { return this.pushTransaction(pushTransactionRequest); } catch (TransactionPushTransactionError transactionPushTransactionError) { throw new TransactionSignAndBroadCastError(transactionPushTransactionError); } } TransactionProcessor(

@Test public void signAndBroadcast() { this.mockDefaultSuccessData(); TransactionProcessor processor = createAndPrepareTransaction(this.defaultActions()); assertNotNull(processor); try { PushTransactionResponse pushTransactionResponse = processor.signAndBroadcast(); assertNotNull(pushTransactionResponse); assertEquals(DUMP_TRANSACTION_ID, pushTransactionResponse.getTransactionId()); } catch (TransactionSignAndBroadCastError transactionSignAndBroadCastError) { transactionSignAndBroadCastError.printStackTrace(); fail("Exception should not be thrown here for calling signAndBroadcast"); } }
