The toHaveValue() method asserts that an element has a specific value. This is a retrying assertion that automatically waits for the element to have the expected value.

Description
The toHaveValue() method checks if an element has a specific value. This is primarily used for form elements like input fields, textareas, and select elements. The method compares the element’s current value with the expected value.
This is a retrying assertion that will automatically re-check the element’s value until it matches the expected value or the timeout is reached.
Usage
import { browser } from 'k6/browser';
import { expect } from 'https://jslib.k6.io/k6-testing/0.5.0/index.js';
export const options = {
  scenarios: {
    ui: {
      executor: 'shared-iterations',
      options: {
        browser: {
          type: 'chromium',
        },
      },
    },
  }
};
export default async function () {
  const page = await browser.newPage();
  // Go to a test page that demonstrates input functionality
  await page.goto('https://quickpizza.grafana.com/login');
  // Fill input and check value
  await page.locator('#username').fill('testuser');
  await expect(page.locator('#username')).toHaveValue('testuser');
  // Check textarea value
  await page.locator('#message').fill('Hello world!');
  await expect(page.locator('#message')).toHaveValue('Hello world!');
  // Check select option value
  await page.locator('#country').selectOption('us');
  await expect(page.locator('#country')).toHaveValue('us');
  // Check initial empty values
  await expect(page.locator('#empty-field')).toHaveValue('');
  // Check that field doesn't have specific value
  await expect(page.locator('#username')).not.toHaveValue('wronguser');
