Study Notes
JavaScriptExecutor in Selenium Webdriver
- JavaScriptExecutor helps execute JavaScript through Selenium Webdriver
- Two methods provided by JavaScriptExecutor:
executeScriptandexecuteAsyncScript
Methods of JavaScriptExecutor
executeScriptmethod:- Purpose: executes a JavaScript code snippet
- Allows executing JavaScript in the context of the current page
- Runs the script as a function in the page
- Can return values such as String, Long, Boolean, List, and WebElement
executeAsyncScriptmethod:- Purpose: executes an asynchronous JavaScript code snippet
- Allows executing asynchronous JavaScript in the context of the current page
- Can return values such as String, Long, Boolean, List, and WebElement
Using JavaScriptExecutor
- No extra plugin or add-on required to use JavaScriptExecutor
import org.openqa.selenium.JavascriptExecutoris required to use JavaScriptExecutor- Useful when Selenium Webdriver cannot perform an operation due to limitations
ScrollBy Method
scrollBymethod: scrolls the current page by the specified amount- Purpose: simulates scrolling on the webpage
Setting Script Timeout
setTimeoutmethod: sets the script timeout in millisecondssetScriptTimeoutmethod: sets the script timeout in Selenium Webdriver
Purpose of JavaScriptExecutor
- Allows executing JavaScript code in the context of the current page
- Enables writing tests more like normal coding
- Helps overcome limitations of Selenium Webdriver
