Selenium WebDriver: How to Handle Ajax Application

A common problem we face during automation using selenium WebDriver is to handle the ajax calls. It is difficult to know when the call is complete and page has been updated. There are several ways to handle the ajax calls. This blog describes them one by one.

We can handle Ajax calls in two ways:

1. Hard Wait - this is most commonly used method but not recommended while doing the automation. Only in some exceptional cases use or for short time use it

·    JAVA: Use java method Thread.Sleep() to suspend execution for specified time. Syntax –

Thread.sleep(1000) // time unit is millisecond

·   Implicit Wait – An implicit wait is to tell WebDriver to stop the DOM for a certain amount of time. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance. Syntax –

driver.manage().timeouts().Implicitly Wait(10, TimeUnit.SECONDS); 

// Time is in  seconds or we can also change Unit in second argument

2.   Explicit Wait: An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. Sample code is as follows -

WebDriver driver = new FirefoxDriver();

driver.get("http://google.co.in");

WebDriverWait myDElement = new WebDriverWait(driver, 10)

.until(ExpectedConditions.presenceOfElementLocated(By.xpath("xxxxx")));

HP QTP : What is a Run-Time Data Table? Where can I find and view this table

Data like parameterized output, checkpoint values, and output values are stored in the Run-time Table. It is an XLS file which is stored in the Test Results Folder.  It can also be viewed in the Test Report. Click on View -> Data Table to display data table.

QTP : How will you check a web application for broken links

You can use the Page Checkpoint which gives a count of valid/invalid links on a page.

HP QTP : What is the difference between functions and actions in QTP

QTP Action	Function
Action is a QTP concept and it can use QTP features like own Object Repository, Data Table, checkpoints etc. Actions help make your Test modular and increase reuse. Example: You can divide your script into Actions based on functionality like Login, Logout etc. It is slow in execution.	Functions is a VB Script programming concept and do not have their own Object Repository or Data Table. Functions help in re-use of your code. Ex:  You can create a Function in your script to concatenate two strings. We can’t use checkpoints in functions, instead of checkpoints we can use validation points (Loops and Conditional statements) Functions are faster in execution than Actions

What is the Difference between Bitmap Check point & Image Check point

Bitmap checkpoint does a pixel to pixel comparison of an image or part of an image.

Image Checkpoint checks the value of an image in your application like alt text, destination URL. Note: You create an image checkpoint by inserting a standard checkpoint on an image object. It is supported only in web environment.
