Uncaught (in promise) waiting for navigation: timed out after 30s

Grafana k6 k6-browser
1

Hi, I had a script for browser testing against a Salesforce org. Not sure why the browser was closed abruptly with error “Uncaught (in promise) waiting for navigation: timed out after 30s”.

Below is my script:

import { chromium } from "k6/experimental/browser";
import { check } from "k6";

export default async function () {
  const browser = chromium.launch({ headless: false, timeout: "1m" });
  const page = browser.newPage();

  try {
    await page.goto("https://test.salesforce.com/", {
      waitUntil: "networkidle",
    });

    page
      .locator('input[id="username"]')
      .type("abc");
    page.locator('input[id="password"]').type("abc");

    await Promise.all([
      page.waitForNavigation(),
      page.locator('input[type="submit"]').click(),
    ]);

    check(page, {
      "title is checked":
        page.locator("//span[@title='Items to Approve']").textContent() ===
        "Items to Approve",
    });
  } finally {
    page.close();
    browser.close();
  }
}

Hi @alex !

For the imports I understand you are using k6 v0.43.0 or k6 v0.43.1. Can you confirm the exact version please.

The error that you mention. Is it a recurrent error when running this test?

I can not test that code with test.salesforce.com site, but I have replicated the same functionality with a k6 test site:

import { chromium } from "k6/experimental/browser";
import { check } from "k6";

export default async function () {
  const browser = chromium.launch({ headless: false, timeout: "1m" });
  const page = browser.newPage();

  try {
    await page.goto('https://test.k6.io/my_messages.php', { waitUntil: 'networkidle' });
    page.locator('input[name="login"]').type('admin');
    page.locator('input[name="password"]').type('123');

    await Promise.all([
        page.waitForNavigation(),
        page.locator('input[type="submit"]').click(),
    ]);

    check(page, {
        'header': page.locator('h2').textContent() == 'Welcome, admin!',
      });
  } finally {
    page.close();
    browser.close();
  }
}

This should work correctly.
Let me know if this helps or please try to provide more details or an example that we can test in order to reproduce the problem.

Thank you.

Hi @Daniel.J
「 The error that you mention. Is it a recurrent error when running this test? 」

：Yes. It is a recurrent error. The browser is closed abruptly due to this error every time. Below is more detail while running this test.
Meanwhile, I have another question about the test result. If a test involves navigation between multiple pages, how do we control when the measurement starts? For example, the script navigates to login page first, then main page, then the functional page… If this is the case, what does the result metrics mean? Like browser_loaded time metric, it’s an aggregated result for all 3 pages? What if I only care about the browser performance for the functional page?

Hi @alex ,

So on your question about how to have separate metrics per page, currently that’s not exactly possible from the summary, as this provides an aggregated view of all metrics, but you can achieve that by redirecting the output, for example to a JSON file or to a TS DB such as Prometheus or InfluxDB and then filter the metrics per specific URL.

See previous community posts that can help you experiment with these options:
