These slidesSlides for getting started with using Nunit and Selenium to test your web applications. Examples in C# with a link to a gitHub repository and a brief Java example.

3. Where to start?

4. Selenium
• Works with most browsers and is multi platform (c#,
Java, Ruby)
• WebDriver /IDE
• Nuget packages
• Selenium.Support
• Selenium.WebDriver
• Grid capabilities
• Hub and clients
• Simple jar file install commands

5. Selenium WebDriver
• Add Selenium to your project
• Add Selenium to your class
• Using OpenQA.Selenium;
• Using OpenQA.Selenium.Firefox;
• Create an instance of the WebDriver
• IWebDriver driver = new FirefoxDriver();
• Interact with that driver
• Go to a web page
• Driver. Navigate().GoToUrl(“http://localhost:82”);
• Find an element on the page
• Driver. FindElement(By.Id("Username"))

6. NUnit
• Add NUnit to your project
• Add NUnit to your class
• Using Nunit.framework;
• Attributes
•
•
•
•
[TestFixture] – indicates the class contains test code
[Test] – indicates that it is a test method
[TestCase]
[TestFixtureSetup] – performed once prior to the tests in that test
fixture being run to initialise
• [TestFixtureTearDown] - performed once after the tests in that test
have run to clean up
Test classes must be public and have a default constructor
• Assert class
• Defines a set of methods you can use to check the post condition

9. PageObject Model
• Create a class for each page in your application
• Extract common elements and web elements to a Base
class that the pages can inherit
• Create your base class
• Add selenium support
• Using OpenQA.Selenium.Support.PageObjects;
• Define the elements on the page
• [FindsBy(How = How.Id, Using = "footer_version")] private IWebElement
version;
• Initialise the elements on the page
• PageFactory.InitElements(driver, this);

10. Nunit test
Example c# nunit test
using System;
using NUnit.Framework;
using RedGate.Deploy.WebAppTests.Pages;
namespace RedGate.Deploy.SmokeTests
{
[TestFixture]
public class VersionTest : SmokeTestBase
{
[Test]
public void LoginPageShowsCurrentVersion()
{
Version expectedVersion = GetType().Assembly.GetName().Version;
LoginPage loginPage = LoginPage.Load(Driver, SmokeTestUrlBase);
Assert.AreEqual("v" + expectedVersion, loginPage.VersionNumber.Trim());
}

11. Demo

12. Example Java test
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
Import org.openqa.selenium.firefox.firefoxdriver;
Public class javaExample {
public static void main(String[] args) throws Exception {
Webdriver driver = new firefoxdriver();
driver.get("http://localhost:8080");
webelement loginname = driver.findelement(By.id("Username"));
loginname.sendkeys("loginname");
Webelement password = driver.findelement(By.id("Password"));
password.sendkeys("loginname");
Webelement loginbutton = driver.findelement(By.id("loginbutton"));
loginbutton.submit();
driver.quit();
}
}

13. Selenium Grid Configuration
Install
• java -jar selenium-server-standalone-2.14.0.jar -role hub
• java -jar selenium-server-standalone-2.14.0.jar -role node -hub
http://localhost:4444/grid/register
Usage
• browser browserName=firefox, version=3.6,platform=LINUX
• DesiredCapabilities capability = DesiredCapabilities.firefox();
• webDriver driver = new RemoteWebDriver(new
URL("http://localhost:4444/wd/hub"), capability);

14. Summary
• Improve confidence in your deployment
• Adding tests is easier than you might think
• Automate gradually
