مایکروسافت ابزار جدیدی را برای تستنویسی برنامههای وب به نام «Playwright» ارائه کرده است. با استفاده از این ابزار امکان انجام تست بر روی Chromium ، Firefox و WebKit با استفاده از یک API وجود دارد.
یک مثال ساده:
import { test, expect } from "@playwright/test";
test.describe("navigation", () => {
test.beforeEach(async ({ page }) => {
// Go to the starting url before each test.
await page.goto("https://playwright.dev/");
});
test("main navigation", async ({ page }) => {
// Assertions use the expect API.
await expect(page).toHaveURL("https://playwright.dev/");
});
}); 
var ext = $('#my_file_field').val().split('.').pop().toLowerCase();
if($.inArray(ext, ['gif','png','jpg','jpeg']) == -1) {
alert('invalid extension!');
}
//binds to onchange event of your input field
$('#myFile').bind('change', function() {
//this.files[0].size gets the size of your file.
alert(this.files[0].size);
});
