how to debug selenium code with highlight element

We can use highlight element for debugging, since in some cases due to mismatch from locators selenium will identify different element while execution, highlighting element will useful to identify the element for action during the execution so that we can modify the element if it is different element. highlight element can be done as follows:

WebDriver driver = new ChromeDriver();

driver.manage().window().maximize();

driver.get(“https://yahoo.com”);

// Locate the web element

WebElement elem = driver.findElement(By.id(“sendBtn”));

// Cast driver to JavascriptExecutor

JavascriptExecutor js = (JavascriptExecutor) driver;

// Highlight the element with a red border

js.executeScript( “arguments[0].style.border=’3px solid blue'”, elem );
