如何在Selenium / Java中将WebElement转换为'if'语句的字符串

Question

I'm automating a webstore in selenium/Java. If the user hasn't selected the size of a product, a message comes up stating 'this is a required field' next to the size. I'm trying to write an 'if' statement that asserts whether this message is present and the action to take if it is, but I cannot get it to work. It would be something along the lines of this:

 WebElement sizeIsRequiredMsg = driver.findElement(By.cssSelector("#advice-required-entry-select_30765)"));
 WebElement sizeSmallButton = driver.findElement(By.cssSelector("#product_info_add > div.add-to-cart > div > button"))

          if (sizeIsRequiredMsg.equals("This is a required field.")) {
              action.moveToElement(sizeSmallButton);
              action.click();
              action.perform();
        }

I've tried a few different variations using the 'this is a required field' message as a web element. Not sure if I need to convert the WebElement for the message to a string somehow? Or include a boolean? Can anyone help?

Try using getText() something like this:

EDIT I have added the correct cssSelectors and added try catch :

WebElement addToCartButton = driver.findElement(By.cssSelector("#product_info_add  button")); 
action.moveToElement(addToCartButton); 
action.click(); 
action.perform(); 

try {
    WebElement sizeIsRequiredMsg = driver.findElement(By.cssSelector(".validation-advice"));
    WebElement sizeSmallButton = driver.findElement(By.cssSelector(".swatches-container .swatch-span:nth-child(2)"))
    if (sizeIsRequiredMsg.getText() == "This is a required field.") {
          action.moveToElement(sizeSmallButton);
          action.click();
          action.perform();
    }

} catch (Exception e) {
    System.out.println(e);
    logger.log(Level.SEVERE, "Exception Occured:", e);
};

Hope this helps you!
