K6: setup: context cancelled if running long time steps in setup

[gushengyuan]

if I process a large list in the setup(), that will meet "context cancelled" issue, and it's ok if I pick a small sub array from this list using slice(...)

export function setup() {
    let users = JSON.parse(usersList).slice(0, 8);
    var data = [];
    for (var i = 0; i < users.length; i++) {
        let deviceId = "230a361e-25cc-3e40-bf44-c30761386" + format(i, "000.##");
        var temp = secureLogin(users[i], deviceId, "1");
        data.push(temp);
    }
    return data;
};

seams like it's timeout, is there a option to set the expiration time for that?

I just encountered the same behavior : I have a for loop in setup context building the test materials (random stuff), and when the loop take too much time, I get this :

time="2018-05-28T17:41:54Z" level=error msg="Engine error" error="setup: context cancelled at setup [...]"

I dig a little bit and found that the iteration count is not incremented during setup phase, and execution context goes to timeout at this condition :

Does anyone have an idea to bypass this ? Maybe add a timeout option and/or simply ignore iteration count for the setup phase ?

The setup() and teardown() timeouts used to be hardcoded to 10 seconds, but since the recently released version 0.21, there's now an option to change that. Try setting this:

export let options = {
  setupTimeout: "60s"
};

...or whatever value makes sense in your context. I see that I've forgotten to to add those options in the documentation, so I'll fix that in a bit...

Added the setupTimeout and teardownTimeout to the options docs.
