My Java Selenium Test case works fine when run using chrome driver, however the exact same code fails when run using HeadLess HTML driver.
I got the below java code using Katalon Selenium IDE.
import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.ui.*;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
public class QualysScan {
private static ChromeDriver driver;
public static void setUp() throws Exception {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\myuser\\Downloads\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
}
public static void testQualysScan() throws Exception {
driver.get("https://qualysguard.myorg.com/fo/login.php?idm_key=saml2_78743hhh43");
WebElement element = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='userNameInput']")));
driver.findElement(By.id("submitButton")).click();
System.out.println("Title of the page is 8 -> " + driver.getTitle());
WebElement element1 = new WebDriverWait(driver, 50).until(ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='ext-gen14']")));
System.out.println("Title of the page is 9 -> " + driver.getTitle());
}
This test-case works fine when run using chrome browser plugin driver as in the above code.
However, when I switch to headless HTML driver the same code fails with the below error:
Code changes for HeadLess are as below:
public class QualysScan {
private static WebDriver driver;
public static void setUp() throws Exception {
driver = new org.openqa.selenium.htmlunit.HtmlUnitDriver();
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
}
However, running the exported java code gives me the below error:
Output:
Title of the page is 8 -> Sign In
Exception in thread "main" org.openqa.selenium.TimeoutException: Expected condition failed: waiting for element to be clickable: By.xpath: //*[@id='ext-gen14'] (tried for 50 second(s) with 500 milliseconds interval)

I tried to find "ext-gen14" in view source of the page but could not find it. I understand that my page has javascript code.
I also find a few clickable items id using xpath finder plugin as below:
/html/body/div[1]/div[5]/div[2]/a
/html/body/div[1]/div[5]/div[3]/a
/html/body/div[1]/div[5]/div[6]/a
These are buttons and thier entry in the view source shows as below:
<div class="clear"></div>
<div id="top_modules_bar">
<div class="module-tabs-tab module-tabs-tab-selected">
<a onclick="javascript: showProcessing('Dashboard');" href="/fo/compliance/index.php?skip=1" class="module-link">Dashboard</a>
</div>
<div class="module-tabs-tab">
<a onclick="javascript: showProcessing('Policies');" href="/fo/tools/module_landing.php?module=prod_policies" class="module-link">Policies</a>
</div>
<div class="module-tabs-tab">
<a onclick="javascript: showProcessing('Scans');" href="/fo/tools/module_landing.php?module=prod_scans" class="module-link">Scans</a>
</div>
<div class="module-tabs-tab">
<a onclick="javascript: showProcessing('Reports');" href="/fo/tools/module_landing.php?module=prod_reports" class="module-link">Reports</a>
</div>
<div class="module-tabs-tab">
<a onclick="javascript: showProcessing('Exceptions');" href="/fo/tools/module_landing.php?module=prod_exceptions" class="module-link">Exceptions</a>
</div>
<div class="module-tabs-tab">
<a onclick="javascript: showProcessing('Assets');" href="/fo/tools/module_landing.php?module=prod_assets" class="module-link">Assets</a>
</div>
<div class="module-tabs-tab">
<a onclick="javascript: showProcessing('Users');" href="/fo/tools/module_landing.php?module=prod_users" class="module-link">Users</a>
</div>
<div class="clear"></div>
</div>
Can you please suggest how can i make sure that any of these items are loaded properly before i fire the click ?
I was also interested to know as to why would my java code work fine when run using chrome driver and fail when run as a headless HTML driver ?
Kindly suggest.
