Selenium WebDriver Automation Framework-User Defined Functions

User defined functions (UDF) are the functions which are created by users as per their own requirement

 If any functionality needs to be repeatedly used such functions can be written in 1 utility file and called multiple times from any other testcases. They are also called generic functions.

Benefits of User Defined Functions

·         - Can be used in a number of places without rewriting the code.

·         - Code can be made less complex and easier to write.

·         - Parameters can be passed to the function.

·         - Simpler to invoke.

·         - Cleaner and more understandable code

File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
