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

Selenium Node

Selenium Node

SeleniumNode

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
