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.
How to Test WebSocket APIs With Postman?
WebSocket is a communication protocol that provides full-duplex communication channels over a single, long-lived connection between clients and servers. Unlike HTTP, which is a request-response protocol, WebSocket allows both the client and server to send messages to each other independently at any time, enabling real-time data transfer.
