Selenium Essentials: A List of All Essential Syntax and Methods

Driver Initialization

WebDriver driver = new ChromeDriver();

WebDriver driver = new FirefoxDriver();

WebDriver driver = new InternetExplorerDriver();

WebDriver driver = new HtmlUnitDriver();

Element Locators

driver.findElement(By.id(“Id Value”));

driver.findElement(By.name(“Name Value”));

driver.findElement(By.className(“Class Name Value”));

driver.findElement(By.linkText(“Link text Value”));

driver.findElement(By.partialLinkText(“Partial Text ConstantValue”));

driver.findElement(By.tagName(“Tag Name Value”));

driver.findElement(By.cssSelector(“CSS Value”));

driver.findElement(By.xpath(“Xpath Value”));

driver.findElement(new ByAll(By.className(“ElementClass Name”), By.id(“Element Id”), By.name(“Element Name”)))

Elements Operations

WebElement element = driver.FindElement(By.ElementLocator(“Value of ElementLocator”));

element.click();

element.sendKeys(“Input Text”);

element.clear();

element.submit();

element.getAttribute(“type”);

String innerText = element.getText();

boolean enabledstatus = element.isEnabled();

boolean displayedstatus = element.isDisplayed();

boolean selectedstatus = element.isSelected();

//Operation on drop down

Select select = new Select(element);

select.selectByIndex(Integer Index);

select.selectByVisibleText(“Text”);

select.SelectByValue(“Value”);

select.deselectAll();

select.deselectByIndex(Integer Index);

select.deselectByVisibleText(“Text”);

select.deselectByValue(“Value”);

WebElement selectedOptions = select.getOptions();

Browser Operations

String pageTitle = driver.getTitle();

String currentURL = getCurrentUrl();

String currentPageSource = driver.getPageSource();

// Navigation history

driver.get(“https://www.facebook.com/”);

driver.manage().window().maximize();

driver.navigate().to(“https://www.google.com/”);

driver.navigate().back();

driver.navigate().forward();

driver.navigate().refresh();

driver.close();
driver.quit();
// Handle Alert
Alert alert = driver.switchTo().alert();
alert.accept();
alert.dismiss();
alert.getText();
alert.sendKeys(“Input Data”);
//Handle Cookies
Cookie cookie = new Cookie(“cookieName”, “cookieValue”);
driver.manage().addCookie(cookie);
driver.manage().getCookies();
driver.manage().getCookieNamed(arg0);
driver.manage().deleteAllCookies();
driver.manage().deleteCookieNamed(arg0);
// Handle frames
driver.switchTo().frame(int Frame Index);
driver.switchTo().frame(“frameName”);
WebElement element = driver.FindElement(By.ElementLocator(“Value of ElementLocator”));
driver.switchTo().frame(element);
driver.SwitchTo().defaultContent();

Screenshots Capture
TakesScreenshot screenshot =((TakesScreenshot)driver);
File srcFile= screenshot.getScreenshotAs(OutputType.FILE);
FileHandler.copy(srcFile, destFile);

Manage Timeouts
driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
welement = wait.until(Syntax: WebDriverWait wait = new WebDriverWait(driver, timeout); ExpectedConditions.elementToBeClickable(locator));welement.click();
Thread.sleep(Long milli-seconds)
driver.manage().timeouts().pageLoadTimeout(30,TimeUnit.SECONDS);

Scroll Down or Up Web Page
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript(“window.scrollBy(0,100)”);
js.executeScript(“window.scrollTo(0,document.body.scrollHeight)”);
WebElement element =driver.FindElement(By.ElementLocator(“Value of Element Locator”));
js. executeScript(“arguments[0].scrollIntoView()”, element);

Different approaches to creating XPath and CSS Selector

Description	XPath	CSS Selector
Whole WebPage	html
Whole WebPage body	/html/body	body
image element	//img	img
Link	//a[@href = ‘url’]	a[href = ‘url’]
Direct Child	//div/a	div > a
Id	//tagName[@id=’idValue’]	tagName#idValue
Class	//tagName[@class=’classValue’]	tagName.Value of Classattribute
Attribute	//tagname[@attribute-name=’value1′]	tagName[attribute=Value of attribute]
Multiple Attributes	//input[@type=’submit’ and @name=’btnLogin’]	tagname[attribute1=’val ue1′][attribute2=’value2′]
Contains	//*[contains(@type,’sub’)]	<HTMLtag><[attribute*=subString]>
Starts with	//tagname[starts-with(@attribute, ‘Start value’)]	<HTMLtag><[attribute^=prefix of the String]>
Ends with	//tagname[ends-with(@attribute, ‘End value’)]	<HTMLtag><[attribute$=suffix of the String]>
Matches	//*[matches(@type,’value’)]	N/A
First Child	//ul[@id=’list’]/li[1]	ul#list li:first-child
Last Child	//ul[@id=’list’]/li[last()]	ul#list li:last-child
nth Child	//ul[@id=’list’]/li[3]	ul#list li:nth-child(3)
Text Value	//td[text()=‘textname’]	N/A
Element preceding some sibling	//E2/preceding-sibling::E1	N/A
Sibling element immediately preceding	//E/preceding-sibling::*[1]	N/A
User interface element that is disabled	//E[@disabled]	E:disabled
Checkbox (or radio button) that is checked	//*[@checked]	*:checked
Text Value	//td[text()=‘textname’]	N/A
