Expand description


Have you ever been attacked by a goose?

Goose is a load testing framework inspired by Locust. User behavior is defined with standard Rust code.

Goose load tests, called Goose Attacks, are built by creating an application with Cargo, and declaring a dependency on the Goose library.

Goose uses reqwest to provide a convenient HTTP client.
