HTMLUnitDriver returning error in Selenium Automation Testing which ChromeDriver doesn't

Question

Aim: To use headless option for selenium testing of login page.(HTMLUnitDriver preferable)

I am trying to automate a login to a site using HTMLUnitDriver.

When I sendKeys to an element, it throws an error.

HtmlUnitDriver driver = new HtmlUnitDriver();
driver.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
driver.get("https://bigData/login.jsp");
WebDriverWait usernameWait = new WebDriverWait(driver, 3);
usernameWait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//input[@id=\"username\"]")));
driver.findElement(By.xpath("//input[@id=\"username\"]")).sendKeys("admin");

Error:

Exception in thread "main" org.openqa.selenium.ElementNotInteractableException: You may only interact with visible elements

I tried the same with ChromeDriver. It works fine! It didn't throw this exception. But I could not use the headless option in it.

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
WebDriver driver = new ChromeDriver(chromeOptions);

returns,

Exception in thread "main" org.openqa.selenium.TimeoutException: Expected condition failed: waiting for presence of element located by: By.xpath: //input[@id="username"] (tried for 3 second(s) with 500 milliseconds interval)

Works fine, only when chromeOptions is not defined while initializing chromeDriver.

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
WebDriver driver = new ChromeDriver();

Please guide me what could be these scenarios/suggest an alternative?

As per the documentation, ElementNotInteractableException is the W3C exception which is thrown to indicate that although an element is present on the DOM TREE, it is not in a state that can be interacted with.

Code you can try out is :

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME ,true);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.get("https://bigData/login.jsp");
WebDriverWait usernameWait = new WebDriverWait(driver, 30);
usernameWait.until(ExpectedConditions.visibiltyOfElementLocated(By.xpath("//input[@id=\"username\"]")));
usernameWait.until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@id=\"username\"]")));
driver.findElement(By.xpath("//input[@id=\"username\"]")).sendKeys("admin");

try out this code and let me know the status.

Superb Cruise! Thanks a ton! I understand the workaround you used :) — Mike, Apr 15 '18 at 14:48
