Unable to handle Microsoft login authentication popup in headless chrome[Selenium using java]

Question

I am automating the web application to run in Headless Chrome. ChromeDriver Version:- ChromeDriver 74.0.3729.6 Application Login screen has windows popup to enter username and password. I used alerts to handle the popup in normal chrome

WebDriverWait wait = new WebDriverWait(driver, 18);
wait.until(ExpectedConditions.alertIsPresent());
Alert alert = driver.switchTo().alert();
alert.sendKeys("username" + Keys.TAB + "password");
alert.accept(); 

When Chrome is set to headless, windows popup is not displaying. I could only see blank screen in screenshots.

Also, i tried adding the chromeoptions as

String path = "path to chromedriver";
System.setProperty("webdriver.chrome.driver", path);
System.setProperty("webdriver.chrome.logfile", "./chromedriver.log");
System.setProperty("webdriver.chrome.verboseLogging", "true");
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--disable-gpu");
options.addArguments("--disable-popup-blocking");
driver = new ChromeDriver(options);

ChromeDriverLog has the default values as

"default_content_settings": {
         "geolocation": 1,
         "mouselock": 1,
         "notifications": 1,
         "popups": 1,
         "ppapi-broker": 1
      }

Answer 1

With the current implementation of ChromeDriver and Chrome using switchTo().alert() may not the best possible way to work through Basic Authentication functionality. Instead, an ideal and elegant way would be to embedded the credentials in subresource requests. An example:

• Code Block:

  import java.io.IOException;
  
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.chrome.ChromeDriver;
  import org.openqa.selenium.chrome.ChromeOptions;
  
  public class BasicAuthentication_Chrome 
  {
      public static void main(String[] args) throws InterruptedException, IOException 
      {
          System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
          ChromeOptions options = new ChromeOptions();
          options.addArguments("start-maximized");
          WebDriver driver =  new ChromeDriver(options);
          driver.navigate().to("http://admin:admin@the-internet.herokuapp.com/basic_auth");
      }
  }

Basic Authentication in headless mode

With --headless mode being enabled Basic Authentication still works as expected. An example:

• Code Block:

  import java.io.File;
  import java.io.IOException;
  
  import org.apache.commons.io.FileUtils;
  import org.openqa.selenium.OutputType;
  import org.openqa.selenium.TakesScreenshot;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.chrome.ChromeDriver;
  import org.openqa.selenium.chrome.ChromeOptions;
  
  public class BasicAuthentication_Chrome 
  {
      public static void main(String[] args) throws InterruptedException, IOException 
      {
          System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
          ChromeOptions options = new ChromeOptions();
          options.addArguments("start-maximized");
          options.addArguments("--headless");
          WebDriver driver =  new ChromeDriver(options);
          driver.navigate().to("http://admin:admin@the-internet.herokuapp.com/basic_auth");
          Thread.sleep(3000);
          File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
          FileUtils.copyFile(scrFile, new File(".\\Screenshots\\headless.png"));
      }
  }
