Selenium C# Automation with ChromeDriver

Module: Complete Selenium Automation using ChromeDriver in C#

This guide takes you step-by-step through downloading ChromeDriver, setting up a Selenium project in Visual Studio using NUnit, automating actions on the OrangeHRMS demo site, and generating test reports. No prior coding or test automation experience required.

1. Download ChromeDriver

Open https://chromedriver.chromium.org/downloads
Find your current Chrome version: Open Chrome → 3-dot menu → Help → About Google Chrome
Download the matching version of ChromeDriver ZIP file
Extract and place the chromedriver.exe file into a known location (e.g., C:\WebDrivers)

2. Install Visual Studio and Create Project

Step-by-Step:

Install Visual Studio 2022
Choose .NET desktop development during installation
After opening Visual Studio → Create New Project → Choose NUnit Test Project (.NET Core)
Project Name: OrangeHRMSAutomation

3. Add Selenium and Reporting Packages

Right-click the project → Manage NuGet Packages → Install:

Selenium.WebDriver
Selenium.WebDriver.ChromeDriver
NUnit (if not already added)
ExtentReports for HTML reporting: ExtentReports.Core

4. Set Up Basic Selenium Test

Create a test class `LoginTest.cs`:


using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using AventStack.ExtentReports;
using AventStack.ExtentReports.Reporter;

namespace OrangeHRMSAutomation
{
    public class LoginTest
    {
        IWebDriver driver;
        ExtentReports extent;
        ExtentTest test;

        [OneTimeSetUp]
        public void SetupReporting()
        {
            var htmlReporter = new ExtentHtmlReporter("TestReport.html");
            extent = new ExtentReports();
            extent.AttachReporter(htmlReporter);
        }

        [SetUp]
        public void StartBrowser()
        {
            driver = new ChromeDriver(@"C:\WebDrivers"); // Update path
            driver.Manage().Window.Maximize();
            driver.Navigate().GoToUrl("https://opensource-demo.orangehrmlive.com/");
        }

        [Test]
        public void LoginToOrangeHRMS()
        {
            test = extent.CreateTest("Login Test").Info("Test Started");

            try
            {
                driver.FindElement(By.Name("username")).SendKeys("Admin");
                driver.FindElement(By.Name("password")).SendKeys("admin123");
                driver.FindElement(By.CssSelector("button[type='submit']")).Click();

                Assert.IsTrue(driver.Url.Contains("dashboard"));
                test.Pass("Login successful");
            }
            catch (Exception ex)
            {
                test.Fail("Test failed: " + ex.Message);
                throw;
            }
        }

        [TearDown]
        public void EndTest()
        {
            driver.Quit();
        }

        [OneTimeTearDown]
        public void GenerateReport()
        {
            extent.Flush();
        }
    }
}

5. Run Your Test

From Visual Studio:

Open Test Explorer (View → Test Explorer)
Build your solution
Click Run All

💡 After the test runs, check your project folder for TestReport.html. Open it in a browser to view a detailed report.

6. Add More Tests: Add New Employee (Example)

Continue recording actions using Chrome → Inspect → Copy Locators

Click Admin → Users → Add
Fill user details
Click Save

Use the same approach in a new test method.

7. Page Object Model (Bonus)

Create a separate class for each page (e.g., LoginPage.cs)
Define methods like Login() and reuse them across test classes
Makes your tests modular, reusable, and maintainable
