WebDriver’s most popular Commands

Most common functions used in WebDriver to make a web-application testing.

1. IsElementPresent/Text Present
   1. Finding elements by using function that take argument of By classprivate boolean isElementPresent(WebDriver driver, By by)
try{
driver.findElement(by);
return true;
}
catch(Exception e)
{
return false;
}
}
   2. Using the size to decide whether element is there or not
      if(driver.findElements(Locator).size()>0
{
return true
}else
{
return false
}
}
   3. Finding the text using the PageSourcedriver.PageSource.Contains("TEXT that you want to see on the page");
2. Finding WebElement  by using various locators
   1. Using ID  WebElement welement = driver.findElement(By.id("Id from webpage"));
   2. Using Name  WebElement welement = driver.findElement(By.name("Name of WebElement"));
   3. Using Tag Name  WebElement welement = driver.findElement(By.tagName("tag name"));
   4. Using Xpath  WebElement welement = driver.findElement(By.xpath("xpath of  webElement"));
   5. Using CSS  WebElement welement = driver.findElement(By.CSS("CSS locator path"));
   6. Using LinkText  WebElement welement = driver.findElement(By.LinkText("LinkText"));
3. Fetching pop-up message
   this is the function that would help you in fetching the message
   
public static String getPopupMessage(final WebDriver driver) {
String message = null;
try {
Alert alert = driver.switchTo().alert();
message = alert.getText();
alert.accept();
} catch (Exception e) {
message = null;
}
System.out.println("message"+message);
return message;
}
4. Canceling pop-up
   public static String cancelPopupMessageBox(final WebDriver driver) {
String message = null;
try {
Alert alert = driver.switchTo().alert();
message = alert.getText();
alert.dismiss();
} catch (Exception e) {
message = null;
}
return message;
}
5. Inserting string in Text Fieldpublic static void insertText(WebDriver driver, By locator, String value) {
WebElement field = driver.findElement(locator);
field.clear();
field.sendKeys(value);
}
6. Reading ToolTip text
   public static String tooltipText(WebDriver driver, By locator){
String tooltip = driver.findElement(locator).getAttribute("title");
return tooltip;
}
7. Selecting Radio Button
   public static void selectRadioButton(WebDriver driver, By locator, String value){ List select = driver.findElements(locator);
for (WebElement element : select)
{
if (element.getAttribute("value").equalsIgnoreCase(value)){
element.click();
}
}
8.  Selecting CheckBox
   
public static void selectCheckboxes(WebDriver driver, By locator,String value)
{
List abc = driver.findElements(locator);
List list = new ArrayListArrays.asList(value.split(",")));
for (String check : list){
for (WebElement chk : abc){
if(chk.getAttribute("value").equalsIgnoreCase(check)){
chk.click();
}}}}
9. Selecting Dropdownpublic static void selectDropdown(WebDriver driver, By locator, String value){
new Select (driver.findElement(locator)).selectByVisibleText(value); }
10. Selecting searched dropdownpublic static void selectSearchDropdown(WebDriver driver, By locator, String value){
driver.findElement(locator).click();
driver.findElement(locator).sendKeys(value);
driver.findElement(locator).sendKeys(Keys.TAB);
}
11. Uploading filepublic static void uploadFile(WebDriver driver, By locator, String path){
driver.findElement(locator).sendKeys(path);
}
12. Downloading fileHere we will click on a link and will download the file with a predefined name at some specified location.
    public static void downloadFile(String href, String fileName) throws Exception{
URL url = null;
URLConnection con = null;
int i;
url = new URL(href);
con = url.openConnection();
// Here we are specifying the location where we really want to save the file.
File file = new File(".//OutputData//" + fileName);
BufferedInputStream bis = new BufferedInputStream(con.getInputStream());
BufferedOutputStream bos = new BufferedOutputStream(
new FileOutputStream(file));
while ((i = bis.read()) != -1) {
bos.write(i);
}
bos.flush();
bis.close();
13. Wait()
    1. Implicit Wait :
       driver.manage.timeouts().implicitlyWait(10,TimeUnit.SECONDS);
    2. Explicit Wait:WebDriverWait wait = new WebDriverWait(driver,10);
wait.until(ExpectedConditons.elementToBeClickable(By.id/xpath/name("locator"));
    3.  Using Sleep method of java
       Thread.sleep(time in milisecond)
14. Navigation method of WebDriver Interface
    
    
    1. to() method (its a alternative of get() method)
       driver.navigate().to(Url);
       This will open the URL that you have inserted as argument
    2. back() – use to navigate one step back from current position in recent history syntax == driver.navigate().back();
    3. forward() – use to navigate one step forward in browser historydriver.navigate().forward();
    4. refresh() – This will refresh you current open urldriver.navigate().refresh();
15. Deleting all Cookies before doing any kind of action  driver.manage().deleteAllCookies();
    This will delete all cookies
16. Pressing any Keyboard key using Action builder class of WebDriverWebDriver has rewarded us with one class Action to handle all keyboard and Mouse action. While creating a action builder its constructor takes WebDriver as argument. Here I am taking example of pressing Control key
    Actions builder = new Actions(driver);
builder.keyDown(Keys.CONTROL).click(someElement).click(someOtherElement).keyUp(Keys.CONTROL).build().perform();When we press multiple keys or action together then we need to bind all in a single command by using build() method and perform() method intend us to perform the action.
    In the same way you can handle other key actions.
17. Drag and Drop action in Webdriver
    In this we need to specify both WebElement means Source and target and for draganddrop Action class has a method with two argument so let see how it normally look like
    WebElement element = driver.findElement(By.name("source"));
WebElement target = driver.findElement(By.name("target"));
(new Actions(driver)).dragAndDrop(element, target).perform();
