Understanding locator.isVisible() in Playwright

In Playwright, locator.isVisible() checks if an element is visible right away. It doesn't wait for the element to become visible.

Here's how it works:

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

test('Check visibility', async ({ page }) => {
  await page.goto('https://ray.run');
  const locator = page.locator('.your-selector');
  const isVisible = await locator.isVisible();
  console.log(isVisible);
});

If the selector doesn't match any elements, Playwright considers it not visible. So, if there are no matching elements in the DOM, locator.isVisible() will return false.

This might be different from what you're used to with other frameworks. Some wait for an element to become visible before returning a result. But with Playwright, you need to handle waiting explicitly if needed.

If you want to wait for an element to become visible, you can use waitFor(). This method lets you specify conditions based on various states of an element.

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

test('Wait for visibility', async ({ page }) => {
  await page.goto('https://ray.run');
  const locator = page.locator('.your-selector');
  await locator.waitFor('visible');
  // Perform further actions or assertions
});

So, remember, locator.isVisible() in Playwright returns immediately. If you need to wait for visibility changes, use waitFor().
