How do you load test WebSockets?

You can use a load-testing tool for that. I have used WebLOAD in a similar project. It records the web traffic when using the browser – it records regular HTTP requests and also the web-sockets traffic – you can then play the script back with many users and measure the server’s behavior.

How is WebSocket performance measured?

WebSocket Performance Testing in 4 Simple Steps

1. Step 1: Create a Test Case. Make sure you sign up for a Testable account first.
2. Step 2: Write Test Script. Choose Node.
3. Step 3: Configure a Load Test. Click Next to move onto the Configuration step.
4. Step 4: View the Results.

How load testing can be done?

How to do Load Testing

1. Create a dedicated Test Environment for load testing.
2. Determine the following.
3. Load Test Scenarios.
4. Determine load testing transactions for an application. Prepare Data for each transaction.
5. Test Scenario execution and monitoring.
6. Analyze the results.
7. Fine-tune the System.
8. Re-test.

How do I test a WebSocket in Chrome?

Here are the steps to test it quickly:

1. Navigate to the WebSocket Echo demo, hosted on the websocket.org site.
2. Turn on the Chrome Developer Tools.
3. Click Network, and to filter the traffic shown by the Dev Tools, click WebSockets.
4. In the Echo demo, click Connect.
5. Click the Send button in the Echo demo.

Does JMeter support WebSocket?

Unfortunately, Apache JMeter™ doesn’t support the WebSocket protocol out of the box. But there are a couple of plugins we can use to help with that.

What is Socket programming?

What is socket programming? Socket programming is a way of connecting two nodes on a network to communicate with each other. One socket(node) listens on a particular port at an IP, while other socket reaches out to the other to form a connection. Server forms the listener socket while client reaches out to the server.

Why WebSockets are faster than HTTP?

The WebSocket protocol offers a persistent connection to exchange messages. Since WebSockets were designed specifically for long-lived connection scenarios, they avoid the overhead of establishing connections and sending HTTP request/response headers, resulting in a significant performance boost.

What is load testing with example?

Examples of load testing include Downloading a series of large files from the internet. Running multiple applications on a computer or server simultaneously. Assigning many jobs to a printer in a queue. Subjecting a server to a large amount of traffic. Writing and reading data to and from a hard disk continuously.

What is the example of load testing *?

Some basic examples of load testing are: Testing a printer by transferring a large number of documents for printing. Testing a mail server with thousands of concurrent users. Testing a word processor by making a change in the large volume of data.

How do I know if a WebSocket is open?

You can check if a WebSocket is connected by doing either of the following:

1. Specifying a function to the WebSocket. onopen event handler property, or;
2. Using addEventListener to listen to the open event.

How do I start running load tests for my WebSocket application?

Sign up for the LoadView free trial and start running load tests for your WebSocket-based applications. You will get $20 in load testing credits to start. Or schedule your own one-on-demo with one of our performance engineers.

Is there a free plug-in for JMeter or WebSocket testing?

Needless to say both JMeter and WebSocket plug-in is open-source and free to use. You can use a load-testing tool for that. I have used WebLOAD in a similar project.

How to simulate a WebSocket?

Basically it boils down to how to simulate a websocket. I can give you a suggestion from my recent experience. You can connect webkit based Phantom virtual clients to your chat server and measure the resource usage (i.e CPU, memory, may be using a shell script or another utility or you can profile your service )

What is a WebSocket (WS) API?

In order to help a WebSocket create and manage its connection to a server, a WebSocket (WS) API object is needed. Once the connection is created, the WS API also sends and receives data on the connection it has created.
