Selenium Interview Questions and Answers | Scenario based and some tricky Questions with Answers

41. Explain what is Group Test in TestNG?

In TestNG, methods can be categorized into groups. When a particular group is being executed, all the methods in that group will be executed. We can execute a group by parameterizing it’s name in group attribute of @Test annotation. Example: @Test(groups={“xxx”})

8. What is Page Factory?

Page Factory gives an optimized way to implement Page Object Model. When we say it is optimized, it refers to the fact that the memory utilization is very good and also the implementation is done in an object oriented manner.

Page Factory is used to initialize the elements of the Page Object or instantiate the Page Objects itself. Annotations for elements can also be created (and recommended) as the describing properties may not always be descriptive enough to differentiate one object from the other.

The concept of separating the Page Object Repository and Test Methods is followed here also. Instead of having to use ‘FindElements’, we use annotations like: @FindBy to find WebElement, and initElements method to initialize web elements from the Page Factory class.

@FindBy can accept tagName, partialLinkText, name, linkText, id, css, className & xpath as attributes.
