private void startWebdriver() throws UIException{
    //2) Prevent re-use.
    if(UIHandlerWD.this.profile == null)
        throw new 
            UIException(
                UIException.Code.UI, 
                    "Webdriver instance cannot be instantiated."
            );              

    //3) Configure Selenium Webdriver.
    if (this.profile.browserType.equalsIgnoreCase("*firefox")){
        FirefoxProfile fProfile = new FirefoxProfile();

       // profile.SetPreference("network.http.phishy-userpass-length", 255);
        fProfile.setAcceptUntrustedCertificates(true);
        DesiredCapabilities dc = DesiredCapabilities.firefox();
        dc.setJavascriptEnabled(true);
        dc.setCapability(FirefoxDriver.PROFILE, fProfile);

        //this.webdriver = new FirefoxDriver(dc);
        this.webdriver = new FirefoxDriver(dc);
    }
    else if (this.profile.browserType=="INTERNETEXPLORER")
        this.webdriver = new InternetExplorerDriver();
    else
        throw new 
        UIException(
            UIException.Code.UI, 
                "Unknown browser type '" + this.profile.browserType +"'."
        );          


    //4) Start Webdriver.
    this.webdriver.get(this.profile.getURL().toString());
    this.webdriver.manage().timeouts().
    implicitlyWait(5, TimeUnit.SECONDS);
    this.webdriver.manage().timeouts().
    pageLoadTimeout(this.profile.timeout, TimeUnit.SECONDS);

}

void stopWebdriver() {
    if(this.webdriver != null){
        try{
        Thread.sleep(5000);
        }
    catch (Exception e) {
        // TODO: handle exception
    }
        this.webdriver.close();
    }
    this.webdriver = null;
    this.profile = null;
}

回答1:

Add webdriver.quit() to an @AfterClass method.

close() will shut the current active window. If the current active window is the last window it is functionally equivalent to performing a quit().

It does however need to have a valid active session to be able to do this. If your test has failed that session is probably dead, so when you call a close() it doesn't know where to send the command and throws an Exception.

quit() will end all sessions and shut down all clients, it's basically a clean up everything command. It will also not throw any Exceptions if all clients/sessions have already been closed/ended.
