Selenium Questions:
What is the difference between selenium 3 and selenium 2? Which one do you incorporate in your framework? How does Selenium interact with the Web browser?
-(Selenium IDE + Selenium RC + Selenium Grid)Selenium 2 and 3 (Selenium IDE + Selenium RC + Selenium WebDriver + Selenium Grid) -We are using the Selenium 3.0 because of compatibility issues which can support most ofthe latest browsers any way we are creating maven project any dependency we can easily update in pom.xml file
What is the difference between Assert and Verify in Selenium?
-Assert: Ifthe assert condition is true then the program control will execute the next test step but ifthe condition is false, the execution will stop and further test step will not be executed. -Verify: Whether verified condition is true or false test script execution will continue
What is the difference?
Difference between both Xpath and CSS: -Generally CSS is easy to use and readable over XPATH. CSS is native to browsers and XPATH is not Speed wise CSS and XPATH can be equal, or either one would be a bit speedier than other. Therefore speed comparison can be ignored. However, off the record, I have encountered that CSS is much faster than XPATH in IE Browser.
Suppose developer changed the existing image to new image with same xpath. Is test case pass or fail?
No test case will pass because we can not check image using selenium.
Is it possible to automate the captcha using Selenium? List some scenarios which we cannot automate using Selenium WebDriver?
No we can't automate captcha. Less Support for Image based Testing, No Other Tool integration for Test management
What is Selenium RC?
Selenium RC aka Selenium Remote control / Selenium 1. Selenium WebDriver aka Selenium 2 is a browser automation framework that accepts commands and sends them to a browser. It is implemented through a browser-specific driver. It controls the browser by directly communicating with it.
What is Selenium WebDriver?
Selenium webDriver is one tool in seleniumSelenium 1
How to pause a test execution for 5 seconds at a specific point?
Thread.sleep(5000);
How do you work with radio buttons which do not have id attribute?
We can use click() ,if "id" is not present we can use xpath(i.e you can use relative or absolute) ,css or other locator type
Scenario: there is a submit button in page it has id property. By using id we got element not found exception, how will you handle this situation? What might be the problem this case?
We can use xpath or check that button or check ifthe button is inside the frame or we can use submit() rather than click() or else we can use the javaScriptExecutor for that. Or maybe it takes some extra time for the button to get loaded in DOM. So we can add Explicit wait untilthe element becomes clickable.
Write a program to scroll in selenium until an element is found?
WebElement element = driver.findElement(By.id("id_of_element")); ((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);
Have you done any cross browser testing within your Project?

Write a complex xpath or css expression? Which one is better?
xpath: "//label[@for='personal_txtLicExpDate']/following-sibling::img" Both CSS and XPATH are better in the Selenium Automation When we want to automate the test Case on Internet Explorer then CssSelector is best and for the rest (Browser i.e. Firefox, Chrome and Safari) xpath is better feasible
What are the Open-source Frameworks supported by Selenium WebDriver?
● JUnit ● TestNG ● Cucumber ● JBehave
What is the difference between Absolute Path and Relative Path? What is the difference between "/" and "//". In which situations are you going to use Xpath?
● Single Slash "/" - Single slash is used to create XPath with absolute path i.e. the XPath would be created to start selection from the document node/start node and it is called Absolute XPath. Example : /html/body/td/tr/div[1]/div[2] ---------------------- ● Double Slash "//" - Double slash is used to create XPath with relative path i.e. the XPath would be created to start selection from anywhere within the document. And it is called Relative XPath. Example: //input[@id='username']

What is the difference between using Assertions vs using If condition? What are Soft Assert and Hard Assert in Selenium? What are the verification points available in Selenium?
-Hard assertion break a test immediately with an AssertException after the assert method reports failure. If one ofthe many test cases fails, then the execution continues with the remaining tests. Soft assertion doesn't throw an exception on failure instead it collects allthe errors until it finishes. And that's how we could manage to run allthe steps of a test @Test -In Selenium WebDriver, there is no built-in features for verification points. It totally depends on our coding style. Some ofthe Verification points are: ● To check for page title ● To check for certain text ● To check for certain element (text box, button, drop down, etc.)
How can we handle web based pop-up? How can you handle JavaScript Alerts? Can we inspect an alert? How many ways you can handle alert? How do you get text from an alert? How do you send text to alert? How can we handle windows based pop up?
-How can we handle web based pop-up? How can you handle JavaScript Alerts? Can we inspect an alert? How many ways you can handle alert? How do you get text from an alert? How do you send text to alert? How can we handle windows based pop up? -Alert alert = driver.switchTo().alert(); or driver.switchTo().alert() - 1) void dismiss() - The dismiss() method clicks on the "Cancel" button as soon as the pop up window appears. alert.dismiss(); or driver.switchTo().alert().dismiss(); -2) void accept() - The accept() method clicks on the "Ok" button as soon as the pop up window appears. alert.accept(); or driver.switchTo().alert().accept(); -3) String getText() - The getText() method returns the text displayed on the alert box. alert.getText(); or driver.switchTo().alert().getText(); -4) void sendKeys(String stringToSend) - The sendKeys() method enters the specified string pattern into the alert box. alert.sendkeys("text"); or driver.switchTo().alert().sendkeys("text"); -Selenium WebDriver cannot handle window based pop up, for that we can use AutoIT.
Scenario: you have 2 frames in the page and in 1 you need to enter some text in second you need to click a button. How can you do that? Can you switch from frame to frame directly?

What are the types of waits available in Selenium WebDriver? What is Implicit/ Explicit/ Fluent Wait In Selenium WebDriver?What is WebDriverWait In Selenium WebDriver?
-Implicit Wait: -The implicit wait willtellto the web driver to wait for a certain amount oftime before it throws a "No Such Element Exception". The default setting is 0. Once we set the time, web driver will wait for that time before throwing an exception. -driver.manage().timeouts().implicitlyWait(TimeOut, TimeUnit.SECONDS); -Explicit Wait: -The explicit wait is used to tellthe Web Driver to wait for certain conditions (Expected Conditions) or the maximum time exceeded before throwing an "ElementNotVisibleException" exception. The explicit wait is an intelligent kind of wait, but it can be applied only for specified elements. -WebDriverWait wait=new WebDriverWait(drv,30); -wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("ckdmc")); -Fluent Wait -The fluent wait is used to tellthe webdriver to wait for a condition, as well as the frequency with which we want to check the condition before throwing an "ElementNotVisibleException" exception. Frequency: Setting up a repeat cycle with the time frame to verify/check the condition at the regular interval oftime. -Consider a scenario where an element is loaded at different intervals oftime. The element might load within 10 seconds, 20 seconds or even more than that if we declare an explicit wait of 20 seconds. It will wait tillthe specified time before throwing an exception. In such scenarios, the fluentwait is the ideal wait to use as this willtry to find the element at different frequencies until it finds it or the final timer runs out. -Wait wait = new FluentWait(WebDriver reference); wait.withTimeout(timeout, SECONDS); wait.pollingEvery(timeout, SECONDS); wait.ignoring(Exception.class);

Switch to Frames by Index driver.switchTo().frame(0)
How do you handle an element in different windows? Getwindowhandle vs Getwindowhandles and the return types. Write a method to switch to window based on title?
-We can handle multiple windows in selenium webdriver using Switch To methods which will allow us to switch controlfrom one window to another window. -getWindowHandle() will get the handle ofthe page the webDriver is currently controlling. This handle is a unique identifier for the web page. This is different every time you open a page even if it is the same URL. -Example: String handle= driver.getWindowHandle(); ************************ -getWindowHandles() method or commands returns all handles from all opened browsers by Selenium WebDriver during execution *********************** -//Return a set of window handle -Set<String> handle= driver.getWindowHandles(); -You can use SwitchTo().Window("handle") to switch to the window you desire. You can use SwitchTo().Window("mywindowID"), if you know the window ID. -SwitchTo().Window("") will always go back to the base/main window. -Method to switch to window based on title -public switchToWindow(String titleName) { driver.switchTo().window("titleName"); //titleName = windowName
What operations can you do using the actions class?
-We can perform following operation using action class: ● click (): Simply click on element ● doubleClick (): Double clicks on Element ● contextClick() : Performed a context-click (right click) on an element ● clickAndHold(): Clicks at the present mouse location (without releasing) ●dragAndDrop(source, target): Invokes click-and-hold at the source location and moves to the location of the target element before releasing the mouse. source - element to grab, target - element to release
How to select a value in a dropdown? How to check the multiple selected value in a dropdown?
-We can use Select class -Select dropdown = new Select(driver.findElement(By.id("designation"))); dropdown.selectByVisibleText("Value"); dropdown.selectByIndex(1); dropdown.selectByValue("value"); -isMultiple() Method -isMultiple() method is useful to verify if targeted select box is multiple select box or not means we can select multiple options from that select box or not. It will return boolean (true or false) value. We can use it with if condition before working with select box -Select listbox = new Select(driver.findElement(By.xpath("//select[@id='FromLB']"))); if (blistbox.isMultiple()){ listbox.selectByVisibleText("Value"); listbox.selectByVisibleText("Value"); }

What are the different exceptions you have faced in Selenium WebDriver? What is StaleElementReferenceException? Have you encountered it ever and how you handled it?
● ElementNotVisibleException ● NoSuchElementException ● NoSuchFrameException ● NoAlertPresentException ● NoSuchWindowException ● StaleElementReferenceException - One ofthe worst Exceptions for an automation engineer. WebDriver throw this exception when element is in the DOM and even visible on the screen but you can't access the element as DOM reference change. This can happen if a DOM operation happening on the page is temporarily causing the element to be inaccessible. Solution: We could refresh the page and try again for the same element. or Wait for the element till it gets available -wait.until(ExpectedConditions.presenceOfElementLocated(By.id("table")));
