Download MP4 file instead of playing it using ChromeDriver?

ChromeOptions options = new ChromeOptions();Map<String, Object> prefs = new HashMap<String, Object>();prefs.put("profile.default_content_settings.popups", 0);prefs.put("download.default_directory", getClass().getResource("/data/input").toString().replace("%20", " ").replace("file:","").replaceFirst("/", ""));options.setExperimentalOption("prefs", prefs);options.addArguments("--test-type");capabilities.setCapability(ChromeOptions.CAPABILITY, options);

I got this working by below code:

System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");String downloadFilepath = "/path/to/download";HashMap<String, Object> chromePrefs = new HashMap<String, Object>();chromePrefs.put("profile.default_content_settings.popups", 0);chromePrefs.put("download.default_directory", downloadFilepath);ChromeOptions options = new ChromeOptions();HashMap<String, Object> chromeOptionsMap = new HashMap<String, Object>();options.setExperimentalOptions("prefs", chromePrefs);options.addArguments("--test-type");DesiredCapabilities cap = DesiredCapabilities.chrome();cap.setCapability(ChromeOptions.CAPABILITY, chromeOptionsMap);cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);cap.setCapability(ChromeOptions.CAPABILITY, options);WebDriver driver = new ChromeDriver(cap);

This worked greatly for me:

DesiredCapabilities cap = DesiredCapabilities.firefox();FirefoxProfile fprofile= new FirefoxProfile();fprofile.setPreference("browser.download.folderList",2);  //0-desktop,1-file download folder,2-specified locationfprofile.setPreference("browser.download.manager.showWhenStarting", false); //prevent download file windowfprofile.setPreference("browser.download.dir","E:\\Downloadfilebyprogram");fprofile.setPreference("browser.download.manager.focusWhenStarting", false);//fprofile.setPreference("browser.helperApps.alwaysAsk.force", false);//fprofile.setPreference("browser.download.manager.closeWhenDone", true);//fprofile.setPreference("browser.download.manager.useWindow", false);//fprofile.setPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);//fprofile.setPreference("browser.helperApps.neverAsk.openFile,","application/vnd.ms-excel");fprofile.setPreference("browser.helperApps.neverAsk.saveToDisk","application/vnd.ms-excel");fprofile.setPreference("browser.download.manager.alertOnExeOpen", false); //prevent from opening a filecap.setCapability(FirefoxDriver.PROFILE, fprofile);WebDriver driver=new FirefoxDriver(cap);
