Transformation from Manual tester to a Selenium WebDriver Automation specialist

Tasks	Human Interaction (Manual Tester)	WebDriver Commands
Invoke Browser	Tester manually opens the browser Firefox, IE, chrome or Safari	WebDriver driver=new FirefoxDriver(); WebDriver driver=new SafariDriver(); WebDriver driver=new chromeDriver(); WebDriver driver=new InternetExplorerDriver(); This is actually a WebDriver object instantiation and this will invoke the browser according to different WebDriver implementation.
Load URL of Application	Tester manually type’s in the URL http://www.google.com	driver.get("http://www.google.com"); Loads the given url into the browser
Click	Tester clicks on the Search field in the Google home page	driver.findElement(By.cssSelector("#gbqfq")).click(); driver.findElement(By.cssSelector("#gbqfq")).clear(); Click actually comes with clear command in WebDriver. Clear command will simply clear the input field. Basically to avoid the auto-form fill.
Type	Tester types the words manually	driver.findElement(By.cssSelector("#gbqfq")).sendKeys("test"); Types “test” into the input element identified by css selector.
Select from Drop-down	Tester clicks on the Drop-down field and selects the required option	Select select = new Select(driver.findElement(By.tagName ("select"))); select.selectByVisibleText("Apple"); Selects the text displayed as “Apple” in the select combo box which is identified by tag name “select”
Moving between Windows	Tester will simply click on the window or will do a Alt+tab combination to toggle between windows	driver.switchTo().window("windowName"); driver.switchTo().frame("frameName"); We can switch between frames or iframes using above command.
Alert Handling	Tester knows that Alert will be pop-up and then asserts it.	driver.findElement(By.xpath (“<Xpath>”)).click(); Alert alert = driver.switchTo().alert(); alert.accept();
