Below is my code

driver.findElement(By.id("submit")).sendKeys(Keys.ENTER);
WebDriverWait wait = new WebDriverWait (driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("logout-trigger")));
driver.findElement(By.id("search-trigger")).sendKeys(Keys.ENTER);

Answer 1

Referring to the HTML you have shared, you have the following :

driver.findElement(By.linkText("Add to cart")); 

which seems to need some modification in the xpath . Can you try the following line of code instead:

WebElement menuHoverLink = driver.findElement(By.xpath("//a[@title='Add to cart']"));
