Trying to inject an external prefetch library into a scripted test

Hi Pat, I am trying to inject an external prefetch library into a scripted test

Here is the script I wish to inject

var js = document.createElement("script");

js.type = "text/javascript";
js.src = "https://cdnjs.cloudflare.com/ajax/libs/quicklink/2.0.0-alpha/quicklink.umd.js";

js.onload = function() {
    quicklink.listen();
}
document.body.appendChild(js);

Here are the steps I am looking to setup

navigate    https://www.foo.com/
sleep    30
navigate    https://www.foo.com/product-2

I see that the steps are being executed properly but the script is not being injected, am I doing something wrong here?

Appreciate your help as always.

Thanks
Akhil

Ok found the answer to this one. If you are using a scripted WPT test then you cannot inject the script via the “inject script” UI. You need to include it as part of your WPT script. So my script now looks like

navigate https://www.foo.com
execAndWait ar js = document.createElement("script"); js.type = "text/javascript"; js.src = "https://cdnjs.cloudflare.com/ajax/libs/quicklink/2.0.0-alpha/quicklink.umd.js"; js.onload = function() {quicklink.listen();}; document.body.appendChild(js);
sleep 10 
navigate https://www.foo.com/products.html
