Om dette verktøyet

The WebSocket Test Tool enables quick validation of WebSocket endpoints (ws/wss) by establishing a connection, performing the RFC 6455 handshake, sending messages, and inspecting server responses.
It captures timing data to report latency metrics and validates payload integrity, returning structured results that help engineers verify correct behavior under typical and edge-case conditions.
The tool is intended for developers, QA engineers, and operations teams during development, integration testing, or incident response, reducing the need to write bespoke WebSocket clients for routine checks.
Core capabilities include configurable inputs (URL, subprotocols, headers, timeout, message count) and detailed outputs (connection status, handshake details, latency, and error logs).

Frequently Asked Questions

Finn raske svar

What does this tool test?

The tool validates WebSocket endpoints by performing a full handshake (RFC 6455), opening a connection, sending one or more text messages, and verifying the server's echoed responses or payload integrity, while reporting connection status, latency, and error details.

What inputs are required?

At minimum, provide the WebSocket URL with ws or wss. Optional inputs include subprotocols and headers. Additional controls like timeout_ms and max_messages enable deeper validation, but are not mandatory for a basic test.

How is latency calculated?

Latency is the round-trip time measured from sending a message to receiving a corresponding response, averaged across all messages in the test. It reports per-message latency as well as a summary metric.

Is data stored after a test?

No user data is persisted beyond the session. Results are kept in memory for the duration of the test and can be exported if supported, but there is no long-term storage by default.
