TestNG Parameterized Test using @DataProvider

One of the bright feature of TestNG is that to allows pass parameter to test. It can be achieve in two ways...

1. using @DataProvider annotation and

2. with testng.xml

Here is a demonstration how to parameterized test using @DataProvider annotation.

The Data Provider method returns an array of Objects(Objects[][])  where the first dimension's size is the number of times the test method will be invoked and the second dimension size contains an array of objects that must be compatible with the parameter types of the test method.

How to handle iFrames in WebDriver

An IFrame (Inline Frame) is an HTML document embedded inside another HTML document on a website. The IFrame HTML element is often used to insert content from another source, such as an advertisement, into a Web page.

An <iframe> is used for containing (X)HTML documents in other (X)HTML documents. This enables updates of parts of a website while the user browses, without making them reload the whole thing.

If name of iFrame is given then it is easy to deal with

    driver.switchTo().frame("name of iframe");

But in case if name is not given then follow these steps...

First get all elements starting with 'iframe' tag in a list

    List<WebElement> myL = driver.findElements(By.tagName("iframe"));  

Print the size of list (so that you know that how many iframes exist on the web page)

    System.out.println(myL.size());

Use a for loop to get html code of iFrame

    for(int i=0; i<myL.size(); i++){
      
        driver.switchTo().frame(i);                                                
      
        System.out.println("******* iFrame + " +i + " start ***********");

        System.out.println(driver.getPageSource());          //Printing HTML code of iFrame

        System.out.println("******* iFrame + " +i + " end ***********");
      
        driver.switchTo().defaultContent();                     // Switching WebDriver to default content
    }

Once you get the your iFrame html code with frame number then switch on it using

  driver.switchTo().frame(7);
