It k6 extention for stress testing EGTS protocol receivers.
To build a k6 binary with this extension, first ensure you have the prerequisites:
Then, install xk6 and build your custom k6 binary with the EGTS extension:
- Install
xk6:
$ go install github.com/k6io/xk6/cmd/xk6@latest- Build the binary:
$ xk6 build --with github.com/kuznetsovin/xk6-plugin-egts@latestimport egts from "k6/x/egts";
