Currently, I am in the process of automating an end-to-end (E2E) task that involves downloading files from a drop-down menu. The functionality works flawlessly using chromedriver without the headless mode activated. However, when I enable Chrome options for headless mode, the file fails to download.
Within the drop-down menu, clicking on a file opens an external link which then triggers the download of the file before returning to the main screen. My objective is to open and inspect the downloaded file, yet unfortunately, it does not successfully download.
Below is the snippet of code for my Webdriver manager:
String downloadFolder = System.getProperty("user.dir") + "/exportedFiles";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("plugins.always_open_pdf_externally", true);
chromePrefs.put("download.default_directory", downloadFolder);
chromePrefs.put("browser.setDownloadBehavior", "allow");
chromePrefs.put("download.prompt_for_download", "false");
ChromeOptions options = new ChromeOptions();
options.addArguments("headless");
options.addArguments("--test-type");
options.addArguments("--disable-extensions");
options.setExperimentalOption("prefs", chromePrefs);
driver = new ChromeDriver(options);
