Retry http requests in k6

Question

I have a python requests-based suite of API tests that automatically retry every request with a 408 or 5xx response. I'm looking at re-implementing some of them in k6 for load testing. Does k6 have support for retrying http requests?

Answer 1

There is no such functionality in k6, but you can add it fairly simply by wrapping the k6/http functions like:

function httpGet(url, params) {
    var res; 
    for (var retries = 3; retries > 0; retries--) {
        res = http.get(url, params)
        if (res.status != 408 && res.status < 500) {
            return res;
        }
    }
    return res;

}

And then just use httpGet instead of http.get ;)
