Integrating QuickFIX/J with JMeter to test FIX protocol endpoints is a common requirement for financial systems. JMeter does not natively support the FIX protocol, but you can achieve this integration in several ways:

1. Using JSR223 Sampler with Groovy and QuickFIX/J You can use a JSR223 Sampler in JMeter to run Groovy (or Java) code that uses QuickFIX/J to send and receive FIX messages. Steps: A. Add QuickFIX/J JARs to JMeter Download the QuickFIX/J JARs (e.g., quickfixj-core-2.3.0.jar and dependencies). Place them in JMeter’s lib directory. Restart JMeter. B. Prepare Your FIX Configuration File Place your client.cfg (as shown in previous answers) somewhere accessible. C. Add a JSR223 Sampler to Your Test Plan In JMeter, add a Thread Group. Add a JSR223 Sampler to the Thread Group. Set the language to Groovy. /* import quickfix.* import quickfix.field.* import quickfix.fix42.Logon

// Only initialize once per test if (ctx.getThreadNum() == 0 && !props.get("fixInitiatorStarted")) { SessionSettings settings = new SessionSettings("C:/path/to/client.cfg") Application application = new quickfix.ApplicationAdapter() { @Override void onLogon(SessionID sessionId) { log.info("Logon: $sessionId") } @Override void onLogout(SessionID sessionId) { log.info("Logout: $sessionId") } @Override void fromApp(Message message, SessionID sessionId) { log.info("FromApp: $message") } } MessageStoreFactory storeFactory = new FileStoreFactory(settings) LogFactory logFactory = new FileLogFactory(settings) MessageFactory messageFactory = new DefaultMessageFactory() Initiator initiator = new SocketInitiator(application, storeFactory, settings, logFactory, messageFactory) initiator.start() props.put("fixInitiatorStarted", "true") props.put("fixInitiator", initiator) }

// Example: Send a Logon message (or any other FIX message) SessionID sessionID = Session.lookupSessionID("FIX.4.2", "CLIENT12", "BROKER12") if (sessionID != null) { Logon logon = new Logon() logon.set(new EncryptMethod(0)) logon.set(new HeartBtInt(30)) Session.sendToTarget(logon, sessionID) } else { log.warn("SessionID not found") }*/

D. Example Groovy Code for JSR223 Sampler Apply to 1.js Note: You may need to adjust the code to manage session lifecycle and message sending/receiving as per your test requirements. 3. Using an External Java Program with JMeter Alternatively, you can run your QuickFIX/J client as a standalone Java program (as shown in previous answers), and use JMeter to interact with it via: Shell scripts (using JMeter’s OS Process Sampler) Files (JMeter writes requests to a file, your Java app reads and sends them) TCP/UDP (JMeter communicates with your Java app over a socket) This is more complex but can be useful for advanced scenarios. 4. Using JMeter Plugins There is no official JMeter plugin for FIX, but some open-source or commercial plugins may exist. Most organizations use the JSR223 approach for flexibility. Summary Table Approach Pros Cons JSR223 + QuickFIX/J Flexible, in-JMeter More setup, scripting needed External Java App Decoupled, reusable More complex integration Custom Plugin Seamless, GUI integration May not exist, less flexible References QuickFIX/J Documentation JMeter JSR223 Sampler If you want a ready-to-use JSR223 Groovy script for a specific FIX message or a sample JMeter test plan, let me know! can you provide the same connection code in js

Absolutely! While QuickFIX/J is for Java, and there’s no official QuickFIX for JavaScript/Node.js, you can use open-source Node.js libraries to connect to a FIX server. The most popular is fixparser. Below is a simple example of how to connect to a FIX server using Node.js and fixparser:

1. Install fixparser Apply to 1.js
2. Sample Connection Code (Node.js) Apply to 1.js
3. How it Works Connects to the FIX server at the specified host/port. Sends a FIX Logon message. Listens for incoming messages and logs them. Handles connection open, close, and error events.
4. Notes You can send other FIX messages using fixParser.createMessage(...) with the appropriate fields. For production, you should handle sequence numbers, heartbeats, and logouts according to the FIX protocol. The fixparser library is suitable for prototyping and light usage. For heavy-duty production, more robust solutions or custom handling may be needed. Let me know if you want an example for sending a specific FIX message, or if you need help with message parsing or session management!

java script

const FixParser = require('fixparser'); const fixParser = new FixParser();

const SENDER_COMP_ID = 'CLIENT12'; const TARGET_COMP_ID = 'BROKER12'; const HOST = '127.0.0.1'; const PORT = 5001;

const fixVersion = 'FIX.4.2'; const heartBtInt = 30;

const fixClient = fixParser.createClient(PORT, HOST, () => { console.log('Connected to FIX server');

// Send Logon message
const logon = fixParser.createMessage(
    new FixParser.Field(35, 'A'), // MsgType = Logon
    new FixParser.Field(49, SENDER_COMP_ID), // SenderCompID
    new FixParser.Field(56, TARGET_COMP_ID), // TargetCompID
    new FixParser.Field(98, 0), // EncryptMethod = None
    new FixParser.Field(108, heartBtInt), // HeartBtInt
);
fixClient.send(logon);

});

fixClient.on('open', () => { console.log('Connection opened'); });

fixClient.on('message', (message) => { console.log('Received:', message.description, message.string); });

fixClient.on('close', () => { console.log('Connection closed'); });

fixClient.on('error', (error) => { console.error('Error:', error); });
