Key Concepts of WebSocket

Key Concepts of WebSocket

Full-duplex Communication: WebSocket enables simultaneous two-way communication, where both parties (client and server) can send and receive messages concurrently. Persistent Connection: Once established, a WebSocket connection remains open, allowing for efficient exchange of data without repeatedly opening new connections. Low Latency: WebSocket reduces latency by eliminating the need for constant polling, making it ideal for real-time applications such as chat applications, live updates, and gaming....

How WebSocket Works

1. WebSocket Handshake:...

Features of WebSocket

WebSocket Requests: Postman allows you to create WebSocket requests just like HTTP requests. This includes defining WebSocket endpoints and customizing headers. Message Sending and Receiving: You can send both text and binary messages through WebSocket connections in Postman and view the server’s responses in real-time. Response Validation: Postman supports assertions on WebSocket responses, enabling you to validate the content, status, or headers of WebSocket messages. Scripting: Utilize Postman’s scripting capabilities (using JavaScript) to manipulate WebSocket messages, perform dynamic validations, or handle complex workflows during testing....

Approach

Open Postman WebSocket Request: Launch Postman and create a WebSocket request. Enter WebSocket URL: Input the WebSocket URL of the API to test. Send Messages: Transmit messages to the server and analyze responses. Verify Response Data: Use Postman’s response visualization to ensure correct behavior. Test WebSocket Events: Observe connection status and handle errors during communication....

Testing WebSocket APIs with Postman

Step 1: Create a New WebSocket Request...

Conclusion

So, Postman can be used to work with sockets by sending and receiving messages as shown in example. More importantly we can also manage the the headers and parameters and thus for complex functionality we can use them. Using postman as testing tool standardise the things and thus it will be more helpful....
