Understanding .locator(visible) in Playwright

The .locator(visible) method in Playwright is a handy tool that lets you know if an element is visible on a webpage. It's part of Playwright's Locator API, which provides a way to retrieve one or more elements on a page.

Here's a quick example:

import { test } from '@playwright/test';

test('Check if element is visible', async ({ page }) => {
  await page.goto('https://ray.run/');
  const isVisible = await page.locator('.your-element').isVisible();
  console.log(isVisible); // true or false
});

This method takes an optional options argument, which you can use to set a timeout for waiting for the element to become visible. But remember, this option is ignored and the method returns immediately without waiting for the element to become visible.

Playwright also offers a .locator(isHidden) method. It works similarly to .locator(visible), but it checks if an element is hidden instead.

import { test } from '@playwright/test';

test('Check if element is hidden', async ({ page }) => {
  await page.goto('https://ray.run/');
  const isHidden = await page.locator('.your-element').isHidden();
  console.log(isHidden); // true or false
});

These methods are incredibly useful when writing tests as they allow you to verify the visibility of elements before interacting with them. For more insights on using locators and selectors in Playwright, check out this blog post.
