转换为Webdriver后遇到Selenium Grid问题

从RC切换到Selenium Webdriver后，Selenium Grid不再有效 . 请注意，我的大多数测试仍然在RC中，但是一次只能转换为Webdriver，因此仍然需要Selenium实例 . 看起来我的驱动程序和/或浏览器（Selenium）实例在并行运行时会被覆盖 .

这是我的代码：

public class SeleniumTestSupport
{

    private static Properties singleSharedProperties;
    private static Selenium webmailsingleSharedBrowser;
    protected Selenium webmailbrowser;
    protected WebDriver singleSharedDriver;

    protected WebDriver driver;
    protected Selenium browser;//was protected, now public
    protected static String domain;
    Integer flag = 0;

    @BeforeSuite(alwaysRun = true)
    public void startSeleniumClient() {
    }

    @BeforeTest(alwaysRun = true)
    public void distributeTests(){
    }

    @BeforeClass(alwaysRun = true)
    public void initBrowser() {
    }

    @BeforeMethod(alwaysRun = true)
    public void logIn() {

        singleSharedProperties = new Properties(System.getProperties());
        try {
            singleSharedProperties.load(getClass().getClassLoader().getResourceAsStream("selenium.properties"));
            } catch (FileNotFoundException e) {
            throw new RuntimeException(e);
            } catch (IOException e) {
            throw new RuntimeException(e);
        }

        String serverHost = singleSharedProperties.getProperty("selenium.serverHost", "localhost");
        String serverPortText = singleSharedProperties.getProperty("selenium.serverPort", "4444");
        int serverPort;
        try {
            serverPort = Integer.parseInt(serverPortText);
            } catch (NumberFormatException e) {
            throw new RuntimeException("Unable to parse selenium.serverPort '" + serverPortText + "'");
        }
        String browserStartCommand = singleSharedProperties.getProperty("selenium.browserStartCommand");

        System.out.println("serverhost=" + serverHost);
        System.out.println("serverport=" + serverPort);
        System.out.println("browserStartCommand=" + browserStartCommand);
        System.out.println("url=" + singleSharedProperties.getProperty("teamconnect.url"));


        DesiredCapabilities capability = DesiredCapabilities.firefox();
        singleSharedDriver = new RemoteWebDriver(capability);
        driver=singleSharedDriver;
        browser = new WebDriverBackedSelenium(singleSharedDriver, singleSharedProperties.getProperty("teamconnect.url"));


        String usernamePassword = singleSharedProperties.getProperty("teamconnect.user." + getUserGroup());
        String username = StringUtils.substringBefore(usernamePassword, "/");
        String password = StringUtils.substringAfter(usernamePassword, "/");



        driver.get(singleSharedProperties.getProperty("teamconnect.url"));


        //This code is some setup for each Test, basically, logging into the application...
        LoginPage loginPage = new LoginPage(browser);
        loginPage.setUsername(username);
        loginPage.setPassword(password);
        loginPage.clickLogIn();
        //more code later, removed for brevity


    }

这是一些更多信息：

这是测试的java代码：

包XXXXXXXXXXXXXX;导入XXXXXXXXXXXXXX;

@Test（groups = {“admin”}）公共类EN1200_SR0050_DesignerRightsTest扩展SeleniumTestSupport {

@Test
public void testAllowAllAndDenyAllGroupDesignerRights2() {

    GlobalNavigationPage globalNavigationPage = new GlobalNavigationPage(browser);


    // Click Admin tab from global navigation bar.
    globalNavigationPage.clickAdminTab();

这是GlobalNavigationPage的java代码：

包XXXXXXXXXXXX;

导入XXXXXXXXXXXXXX;

公共类GlobalNavigationPage扩展EntityPage {

Reusable_Actions reusable_Actions = new Reusable_Actions();
Page page = new Page(browser);

public GlobalNavigationPage(Selenium browser) {
    super(browser);
}


public void clickAdminTab() {

    long start = System.currentTimeMillis();

    while (System.currentTimeMillis() - start < WAIT_TIME_IN_SECONDS * 2000) {

        // if element is present return
        if (browser.isElementPresent(LNK_ADMIN)) {
            return;
        }
        // wait for 1/10 of a second
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }}

    driver.findElement(By.id(LNK_ADMIN)).click();
    browser.setTimeout(Integer.toString(WAIT_TIME_IN_SECONDS * 2000));
    browser.waitForPageToLoad(Integer.toString(WAIT_TIME_IN_SECONDS * 2000));
    assertTextNotPresent("System Error Has Occured!");
