JavaScriptExecutor in Selenium WebDriver with Example (easy)

JavaScriptExecutor in Selenium

• The JavaScriptExecutor interface helps to execute JavaScript through Selenium Webdriver.

Methods of JavaScriptExecutor

• The executeScript method is used to run JavaScript on the selected window or current page.
• The executeAsyncScript method is used to run an asynchronous JavaScript.

Purpose of JavaScriptExecutor

• JavaScriptExecutor is used when locators like XPath and CSS do not work in Selenium Webdriver.
• The purpose of using JavaScriptExecutor is to interact with the web page and perform actions that cannot be performed using Selenium's built-in functionalities.

Importing JavaScriptExecutor

• The org.openqa.selenium.JavascriptExecutor package needs to be imported to use JavaScriptExecutor in Selenium.

executeScript Method

• The executeScript method runs the script in the context of the currently selected frame or window.
• The script used in the executeScript method can return values.
• Complicated arguments can be passed to the executeScript method.

executeAsyncScript Method

• The executeAsyncScript method allows writing tests more like normal coding.
• The executeAsyncScript method runs an asynchronous JavaScript.

Script Timeout

• Setting the script timeout to 20 seconds ensures that the script will timeout if it takes longer than 20 seconds to execute.

Browser Sleep

• The purpose of the sleep in the browser under test is to pause the execution of the script.

Window Scroll

• The window.scrollBy(0,600) script is used to scroll the window by 600 pixels.

JavaScriptExecutor Interface

• The JavaScriptExecutor interface object is used to execute JavaScript on the browser.

Log4j Warning Message

• The log4j warning message indicates that there is a problem with the logging configuration.

Site Information

• The domain name of the site can be retrieved using JavaScriptExecutor.
• The URL of the site can be retrieved using JavaScriptExecutor.
• The title of the page can be retrieved using JavaScriptExecutor.

Return Data Types

• The JavaScriptExecutor in Selenium can return various data types, including strings, integers, and objects.

Example Code

• The window.location script is used to retrieve the URL of the site.
• The executeScript method is used to execute JavaScript on the browser.
• The executeAsyncScript method is used to run an asynchronous JavaScript.
