Assert a URL redirection when second URL can not be resolved in TestCafe

Question

I want to assert that the next URL gets resolved. It's a URL generated by SendGrid and changes one you search it in the browser. The problem is that to access the second you need access to our VPN. For security reasons I don't want to run the test behind our VPN but I would like to assert if the redirection from SendGrid is successful (I know exactly what the resolved URL going to look like).

The problems comes when using ClientFunction(() => document.location.href) you will get only a URL that have been resolved successfully, and since I am not connected to the VPN the last URL won't be displayed and cant be asserted.

Is there a way to create an assert after the redirection is done even if I can't resolve the second URL?

await t.navigateTo(URL);

const getLocation = ClientFunction(() => document.location.href);

await t.expect(getLocation()).contains('expected-url');

In this case the expected-url would be: https://app-uat.novemberfirst.cloud.ec/#/public/reset-password/208100002/[email protected]/F1PMDcC05gYhlqh82UDnl183/dan

Found the solution to this.

Basically when making a http request you have to disable any redirection to get the url.

private async resolveRedirectLink(url) {
    let redirectedURL;
    try{
        let response = await fetch(url, {redirect: 'manual'});
        let link = await response.text();
        let matches = link.match(/"(.*?)"/);
        redirectedURL = matches[1];
    }
    catch(error){
        redirectedURL = url;
        console.warn('Error redirecting URL: ' + error.message );
    }
    return redirectedURL;
}

This is the snipped used in my code.
