3. Selenium WebDriver with C# — locators and actions

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;

var options = new ChromeOptions();
options.AddArgument("--headless=new");
using IWebDriver driver = new ChromeDriver(options);     // Selenium Manager downloads the driver automatically (4.6+)
driver.Navigate().GoToUrl("https://shop.example.com/login");

driver.FindElement(By.Id("email")).SendKeys("qa@example.com");
driver.FindElement(By.CssSelector("input[name='password']")).SendKeys("Secret#123");
driver.FindElement(By.XPath("//button[normalize-space()='Sign in']")).Click();

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
var heading = wait.Until(d => d.FindElement(By.CssSelector("[data-testid='dashboard-title']")));
Assert.That(heading.Text, Is.EqualTo("Dashboard"));
