help ghz FAQ

What programming language is the 'ghz' load testing tool built with?

The 'ghz' tool is built entirely using the Go programming language, often referred to as Golang. This allows the tool to leverage Go's native concurrency model to generate massive volumes of simultaneous HTTP requests with minimal system resources.

What protocol does the ghz load testing tool primarily target?

While often used for standard web traffic, 'ghz' was specifically designed as a modern gRPC load testing tool. It allows developers to define and send complex Protobuf payloads to test the performance of microservice architectures.

Is ghz a graphical or command-line load testing tool?

By default, ghz operates strictly as a command-line interface (CLI) tool, making it highly suitable for integration into CI/CD pipelines. However, there are community forks that attempt to provide a web-based GUI wrapper for the engine.

How do you configure requests in the ghz load tester?

Users configure tests by passing command-line flags or by loading a JSON or TOML configuration file that defines the target server and call methods. This makes it highly scriptable for automated regression testing in DevOps environments.
