“/” refers to the immediate child element in the html tree.
“//” refers to any element in the html tree . It also represent any descendant .

@FindBys( {
@FindBy(className =”class1″)
@FindBy(className =”class2″) } )
Private List<WebElement>elementWithBoth_class1ANDclass2;

@FindAll : When the required WebElement objects need to match atleast one of the given criteria use @FindAll annotation
@FindAll ( {
@FindBy(className =”class1″)
@FindBy(className =”class2″) } )

Explicit Wait : It is a one-timer, used for a particular search.
WebDriverWait wait = new WebDriverWait(WebDriverRefrence , TimeOut);

26. What is Syntax of XPath ?

XPath = //tagname[@attribute= ‘Value’]

27. What is difference between in Assert & Verify ?

Verify : Verify command will check whether the element is on the page, if it is not then test will carry on executing, In verification, All command are going to run guaranteed even if any of test fails.

28. What is difference between find elements & find element ?

findElement() : It finds the first element within current page using the given ” Locating Mechanism “. It returns a single WebElement.

findElements() : Using the given ” Locating Mechanism ” it will find all Elements within Current page. It returns a List of WebElements.

29. How you will handle frame() ?

driver.switchTo().fram(“Id of the element”);

30. How to Right click in selenium ?

Actions actions = new Actions (driver) ;
WebElement elementLocator = driver.findElement(By.Id(“ID”));
actions.contextClick(elementLocator).perform() ;

31. If we have findElement and there is no element & findElements there is no elements so what will return ?

findElement – it will throw an exception
findEelements- it will return 0 value

32. What is difference between Explicit wait & Fluent Wait ?

Explicit Wait : It is a one-timer, used for a particular search, it used to tell the web driver to wait for certain conditions( Expected Conditions) or maximum time exceeded before throwing an error “ElementNotVisibleException” Exception.
WebDriverWait wait = new WebDriverWait(WebDriverReference , TimeOut);

Fluent Wait : it used to define maximum time for the web driver to wait for conditions as well as the frequency with which we want to check the condition before throwing an”ElementNotVisibleException” Exception. it checks for the web element at regular intervals untill the object is found or timeout happens.
wait wait = new FluentWait(WebDriver Reference).withTimeout(timeout, SECONDS).pollingEvery(timeout, SECONDS).ignoring(Exception.class);
