What is Selenium?
Which programming languages are supported?
• Install Firefox: https://www.mozilla.org• Install Google Chrome: https://www.google.com/chrome/browser/desktop/• Add c:\Selenium (or similar path on macOS / Linux) to your PATH
Setup Selenium
Requirements
o Internet Explorer Driver:• Download (32bit or 64bit) http://www.seleniumhq.org/download/• Extract to c:\Selenium
o Edge Driver:• Download https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/• Copy to c:\Selenium
o Chrome Driver:• Download https://sites.google.com/a/chromium.org/chromedriver/• Copy to c:\Selenium
o Firefox Driver:• Download https://github.com/mozilla/geckodriver/releases• Extract to c:\Selenium
Setup Selenium
Installing Drivers
A Simple Test
Running a simple Google query[TestMethod] public void GoogleForSelenium() { // Launch new instance for Firefox IWebDriver driver = new FirefoxDriver();
// Navigate to google driver.Navigate().GoToUrl("http://www.google.com");
// Find the input field for the search query IWebElement inputField = driver.FindElement(By.Name("q"));
// Add some text to the input field inputField.SendKeys("Selenium");
// Submit the search inputField.Submit();
// Google uses JS to render the results page so we need to wait var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); wait.Until(o => o.Title.StartsWith("Selenium", StringComparison.OrdinalIgnoreCase));
// Use asserts like you would in unit tests Assert.IsTrue(driver.Title.StartsWith("Selenium", StringComparison.OrdinalIgnoreCase));
// close down the browser driver.Quit(); }
A Simple Test
Demo
A Simple Test[TestMethod] public void GoogleForSelenium_Chrome() { IWebDriver driver = new ChromeDriver(); GoogleForSelenium(driver); }
[TestMethod] public void GoogleForSelenium_Edge() { IWebDriver driver = new EdgeDriver(); GoogleForSelenium(driver); }
[TestMethod] public void GoogleForSelenium_InternetExplorer() { IWebDriver driver = new InternetExplorerDriver(); GoogleForSelenium(driver); }
public void GoogleForSelenium(IWebDriver driver) {
// Navigate to google driver.Navigate().GoToUrl("http://www.google.com");

Selenium Grid can be used to run Selenium tests parallel and on multiple machines. This helps with:
• Reducing the overall time of test execution• Running tests against browsers on different operating systems

1. Download Java: https://www.java.com/en/download/
2. Download Selenium Standalone Server: http://www.seleniumhq.org/download/• Copy to c:\Selenium
3. Start the Hub with the command line:• java -jar selenium-server-standalone-3.0.1.jar -role hub
4. Grid console available at: http://localhost:4444/grid/console
Selenium Grid
Setup a Hub
1. Create a node configuration file:{ "capabilities": [{ "browserName": "firefox", "platform": "WINDOWS", "maxInstances": 1 }],"maxSession": 5,"port": 5555,"register": true}
2. Start the Node with the command line:• java -jar selenium-server-standalone-3.0.1.jar -role node -hub
http://localhost:4444/grid/register -nodeConfig node.json
