Share variable across multiple VUs

[hrai]

I am using multiple VUs to make an auth call. For each VU, the auth call was being made which was not efficient. So I wanted to use a global variable to hold the token value. It seems like the global variable is global only for the VU.

I resolved this issue by using setup and teardown functions as mentioned here.

Example code below:

export function setup() {
  let token = token == null ? getAuthToken() : token;
  return token;
}

export default function (token) {
  let requests = getRequests(token);
  .....

This should be documented so it's easier to find. I spent days trying to find a solution and this pointed me in the right direction

Hi @hrai, I have already opened grafana/k6-docs#148 . I hope this is enough and ... that one day we actually sit down and write that documentation :)
