Selenium Java: How to get current ChromeDriver instance's user directory and version using ChromeCapabilities

Question

I want to know the following information from my current running ChromeDriver:

exact temporary user-data folder that ChromeDriver created by default

the driver version

According to this page, It should be part of the ChromeDriver's returned capabilities:

What I tried so far:

Capabilities caps = DesiredCapabilities.chrome(); System.out.println(caps.getCapability("userDataDir")); System.out.println(caps.getCapability("chrome.chromedriverVersion")); 

Both are giving me null. I do know that I'm not manually setting the ChromeOptions "--user-data-dir" but still, I know that ChromeDriver will use a certain directory by default.

Same goes with the version, It makes sense that we can retrieve the current driver's version at will right?

What am I missing here?

Thanks in advance!

UPDATE 1:
I'm calling the code above right before passing the caps instance as a parameter to the ChromeDriver constructor.

Here's a slightly more insightful snippet:

public class Driver implements WebDriver { private WebDriver webDriver; private Capabilities caps; public Driver(){ caps = DesiredCapabilities.chrome(); caps.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true); caps.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, true); caps.setCapability(CapabilityType.SUPPORTS_ALERTS, true); caps.setCapability(CapabilityType.SUPPORTS_FINDING_BY_CSS, true); //Am I not doing this correctly? System.out.println(caps.getCapability("userDataDir")); System.out.println(caps.getCapability("chrome.chromedriverVersion")); webDriver = new ChromeDriver(caps); } } 

UPDATE 2: Regarding the version number, I realized that whenever I do

Capabilities caps = DesiredCapabilities.chrome(); 

the DesiredCapabilities class is passing a blank string as a parameter to the version number.

With that said, is there any way I can get the current chrome driver version (boxed below)? I know this information is stored somewhere but I do not know how to get it.

As for the temporary user-data folder, I still have no idea how to get it even after watching the capabilities and the webdriver object created.

Appreciate the help!

Thanks to @MikeJRamsey56's casting tip, I managed to figure this out.

Here's a dirty (but) working solution. Hope this can help others out.

public class Driver implements WebDriver { private WebDriver webDriver; private Capabilities caps; public Driver(){ System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY, "the/driver/path/chromedriver.exe"); caps = DesiredCapabilities.chrome(); webDriver = new ChromeDriver(caps); //Cast webDriver instance to RemoteWebDriver caps = ((RemoteWebDriver) webDriver).getCapabilities(); //Call getCapability and cast to Map. //This line will give a Type Safety warning, hence the "dirty" in my solution. Map<String, String> a = (Map<String, String>) caps.getCapability("chrome"); System.out.println(String.format("Driver Version: %s", a.get("chromedriverVersion"))); System.out.println(String.format("Temp dir: %s", a.get("userDataDir"))); } } 

Output:

My initialization logic looks like this:

DesiredCapabilities capabilities = null; System.setProperty("webdriver.chrome.driver", user_dir + "/src/main/resources/drivers/ChromeDriver/chromedriver"); ChromeOptions options = new ChromeOptions(); options.addArguments("start-maximized"); options.addArguments("--disable-extensions"); options.addArguments("--disable-infobars"); Map<String, Object> prefs = new HashMap<String, Object>(); prefs.put("credentials_enable_service", false); prefs.put("profile.password_manager_enabled", false); prefs.put("excludeSwitches", "enable-automation"); options.setExperimentalOption("prefs", prefs); capabilities = DesiredCapabilities.chrome(); capabilities.setCapability("version", "latest"); capabilities.setCapability("browserName", "chrome"); capabilities.setCapability(ChromeOptions.CAPABILITY, options); try { webDriver = new ChromeDriver(options); } catch(Exception e) { System.out.println("**>uh-oh " + e.getMessage()); } webDriver.manage().deleteAllCookies(); Capabilities cap = ((RemoteWebDriver) webDriver).getCapabilities(); String browserName = cap.getBrowserName(); String browserVersion = cap.getVersion(); System.out.println("Browser name=" + browserName + ", version=" + browserVersion);
