Setting separate profiles for Parallel Selenium Tests

Question

I am researching how to set an individual profile using RemoteWebDriver. I have been reading about it on the following thread.

http://stackoverflow.com/questions/12961037/parallel-execution-of-firefoxdriver-tests-with-profile-share-same-profile-copy

I am trying to tackle it as following:

public static RemoteWebDriver getDriver(String methodName) throws MalformedURLException {

    String SELENIUM_HUB_URL = "http://localhost:4444/wd/hub";
    ThreadLocal<RemoteWebDriver> remoteWebDriver = null;

    File currentProfileFile = new File(methodName);
    //This is where it gives the error
    FirefoxProfile currentFireFoxProfile = new FirefoxProfile(currentProfileFile);
    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
    capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    capabilities.setCapability(FirefoxDriver.PROFILE, currentFireFoxProfile);       
    String proxy = System.getProperty("proxy");

    try {
        remoteWebDriver = new ThreadLocal<RemoteWebDriver>();
        remoteWebDriver.set(new RemoteWebDriver(new URL(SELENIUM_HUB_URL),
                capabilities));
        } catch (MalformedURLException e) {
            System.out.println("Please fix the RemoteDriverSetup.class");
        }

    remoteWebDriver.get().manage().window()
            .setSize(new Dimension(2880, 1524));
    remoteWebDriver.get().manage().timeouts()
            .pageLoadTimeout(10, TimeUnit.SECONDS);
    remoteWebDriver.get().manage().timeouts()
            .implicitlyWait(10, TimeUnit.SECONDS);

 return remoteWebDriver.get(); // Will return a thread-safe instance of the WebDriver

}

I am getting the following error :

Time elapsed: 1.044 sec  <<< FAILURE!
org.openqa.selenium.firefox.UnableToCreateProfileException: Given model profile directory does      
not exist: TEST001

Update : I am injecting method name in the BaseTest class below

@BeforeMethod 
public void startTest(Method testMethod) {
        LOG.info("Starting test: " + testMethod.getName());
        this.driver             = WebDriverSetup.getDriver(testMethod.getName());
}

If you don't want to customize anything on your Firefox profile, better to create Firefox webdriver instance by NOT providing any profile details (as mentioned by Nguyen).

If you really want to create separate profiles (may be required to install some plug-ins like Firebug), in that case, you can do that by without passing any file name as below:

   FirefoxProfile currentFireFoxProfile = new FirefoxProfile();
   //Do some customization - add extension
   currentFireFoxProfile.addExtension(pathOfextensionToInstall);

   //or Setup some Firefox config. switch values
   currentFireFoxProfile.setPreference("browser.download.manager.showWhenStarting", false);
