Selenium with Nunit+ExtentReports

6 min readMay 26, 2019

In this article we will create Selenium script and execute as Nunit. We will configure the Nunit+ExtentReports in Visual Studio and then execute the script and generate the html report using ExtentReports.

Step-1: Install Visual Studio Extensions for Nunit

Install “Nunit 3 Test Adapter” plugin.

2. Restart the visual studio to complete the installation

Step-2: Create Class Library project

Launch Visual Studio
Click on “Create a new project” option.

3. Select the project type “Class Library (.Net Framework)”

4. Click on Next button. Enter the Project Name and other details –

5. Click on Create button. Project gets created and shows below screen –

6. Delete the default create class “Class1”.

Step-3: Install NuGet packages for Selenium, NUnit and ExtentReports

Right click on project under Solution Explorer and select “Manage NuGet Packages..”

2. Search and install following packages in the same order as mentioned below —
Selenium.WebDriver.3.141.0
Selenium.Support.3.141.0
NUnit.3.12.0
ExtentReports.3.1.3

3. Now the Solution looks like this –

4. Now the “Packages” folder looks like this –

Step-4: Edit & update the project for Report, Test Cases and Page Methods

Right click on the project and select Add->New Folder. Create below folders -

Config
TestCases
PageMethods

2. Right click on the folder name “Config” and select Add->Class…Create the class name as “ReportsGenerationClass.cs”

3. Update the class “ReportsGenerationClass.cs” as below –

using AventStack.ExtentReports;
using AventStack.ExtentReports.Reporter;
using NUnit.Framework;
using NUnit.Framework.Interfaces;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System.IO;

namespace SeleniumNUnitExtentReport.Config
{
[SetUpFixture]
public abstract class ReportsGenerationClass
{
protected ExtentReports _extent;
protected ExtentTest _test;
public IWebDriver _driver;

[OneTimeSetUp]
protected void Setup()
{
var path = System.Reflection.Assembly.GetCallingAssembly().CodeBase;
var actualPath = path.Substring(0, path.LastIndexOf(“bin”));
var projectPath = new Uri(actualPath).LocalPath;
Directory.CreateDirectory(projectPath.ToString() + “Reports”);
var reportPath = projectPath + “Reports\\ExtentReport.html”;
var htmlReporter = new ExtentHtmlReporter(reportPath);
_extent = new ExtentReports();
_extent.AttachReporter(htmlReporter);
_extent.AddSystemInfo(“Host Name”, “LocalHost”);
_extent.AddSystemInfo(“Environment”, “QA”);
_extent.AddSystemInfo(“UserName”, “TestUser”);
}

[OneTimeTearDown]
protected void TearDown()
{
_extent.Flush();
}

[SetUp]
public void BeforeTest()
{
ChromeDriverService service = ChromeDriverService.CreateDefaultService(“webdriver.chrome.driver”, @”D:\\Automation\\WebDrivers\\chromedriver.exe”);
_driver = new ChromeDriver(service);
_driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(60);
_driver.Manage().Window.Maximize();
_test = _extent.CreateTest(TestContext.CurrentContext.Test.Name);
}

[TearDown]

public void AfterTest()
{
var status = TestContext.CurrentContext.Result.Outcome.Status;
var stacktrace = string.IsNullOrEmpty(TestContext.CurrentContext.Result.StackTrace)? “”
: string.Format(“{0}”, TestContext.CurrentContext.Result.StackTrace);
Status logstatus;
switch (status)
{
case TestStatus.Failed:
logstatus = Status.Fail;
DateTime time = DateTime.Now;
String fileName = “Screenshot_” + time.ToString(“h_mm_ss”) + “.png”;
String screenShotPath = Capture(_driver, fileName);
_test.Log(Status.Fail, “Fail”);
_test.Log(Status.Fail, “Snapshot below: “ + _test.AddScreenCaptureFromPath(“Screenshots\\” + fileName));
break;
case TestStatus.Inconclusive:
logstatus = Status.Warning;
break;
case TestStatus.Skipped:
logstatus = Status.Skip;
break;
default:
logstatus = Status.Pass;
break;
}
_test.Log(logstatus, “Test ended with “ + logstatus + stacktrace);
_extent.Flush();
_driver.Quit();
}
public IWebDriver GetDriver()
{
return _driver;
}

public static string Capture(IWebDriver driver, String screenShotName)
{
ITakesScreenshot ts = (ITakesScreenshot)driver;
Screenshot screenshot = ts.GetScreenshot();
var pth = System.Reflection.Assembly.GetCallingAssembly().CodeBase;
var actualPath = pth.Substring(0, pth.LastIndexOf(“bin”));
var reportPath = new Uri(actualPath).LocalPath;
Directory.CreateDirectory(reportPath + “Reports\\” + “Screenshots”);
var finalpth = pth.Substring(0, pth.LastIndexOf(“bin”)) + “Reports\\Screenshots\\” + screenShotName;
var localpath = new Uri(finalpth).LocalPath;
screenshot.SaveAsFile(localpath, ScreenshotImageFormat.Png);
return reportPath;
}
}
}

4. Right click on the folder name “PageMethods” and select Add->Class…Create the class name as “LoginPage.cs”

5. Update the class “LoginPage.cs” as below —

using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SeleniumNUnitExtentReport.PageMethods
{
class LoginPage
{
private IWebDriver driver;
String toggle_menu = “//a[@id=’menu-toggle’]/i”;
String loginMenu = “//a[contains(text(),’Login’)]”;
String userID = “//input[@id=’txt-username’]”;
String password = “//input[@id=’txt-password’]”;
String loginBtn = “//button[@id=’btn-login’]”;
String menuDashboard = “//section[@id=’appointment’]/div/div/div/h2”;
public LoginPage(IWebDriver driver)
{
this.driver = driver;
}
public void goToPage()
{
driver.Navigate().GoToUrl(“http://demoaut.katalon.com/");
}
public void goToToggleMenu()
{
driver.FindElement(By.XPath(toggle_menu)).Click();
}
public void goToLoginMenu()
{
driver.FindElement(By.XPath(loginMenu)).Click();
}
public void enterUserName(string text)
{
driver.FindElement(By.XPath(userID)).SendKeys(text);
}
public void enterPassword(string text)
{
driver.FindElement(By.XPath(password)).SendKeys(text);
}
public void clickLoginBtn()
{
driver.FindElement(By.XPath(loginBtn)).Click();
}
public Boolean verifyDashboard()
{
Boolean res = driver.FindElement(By.XPath(menuDashboard)).Displayed;
return res;
}
public void closeBrowser()
{
driver.Quit();
}
}
}

6. Now it’s time to generate Test Cases. Right click on the folder name “TestCases” and select Add->Class…Create the class name as “LoginTest.cs”

7. Update the class “LoginTest.cs” as below —

using NUnit.Framework;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SeleniumNUnitExtentReport.Config;
using SeleniumNUnitExtentReport.PageMethods;
namespace SeleniumNUnitExtentReport.TestCases
{
[TestFixture]
public class LoginTest : ReportsGenerationClass
{
LoginPage loginPage;
[Test]
[Category(“Login”)]
public void test_validLogin()
{
loginPage = new LoginPage(GetDriver());
loginPage.goToPage();
loginPage.goToToggleMenu();
loginPage.goToLoginMenu();
loginPage.enterUserName(“John Doe”);
loginPage.enterPassword(“ThisIsNotAPassword”);
loginPage.clickLoginBtn();
Assert.IsTrue(loginPage.verifyDashboard());
loginPage.closeBrowser();
}

[Test]
[Category(“Login”)]
public void test_invalidLogin()
{
loginPage = new LoginPage(GetDriver());
loginPage.goToPage();
loginPage.goToToggleMenu();
loginPage.goToLoginMenu();
loginPage.enterUserName(“John Doe”);
loginPage.enterPassword(“ThisIsNotA”);
loginPage.clickLoginBtn();
Assert.IsTrue(loginPage.verifyDashboard());
loginPage.closeBrowser();
}
}
}

8. Now Project Explorer looks like this –
