Question

我正在使用两个VM作为节点构建一个selenium网格框架（一个是chrome，另一个是Firefox）。当我连续运行我的样本测试时，它们没有任何问题。然而，当我并行运行它们时，Chrome中的测试只能启动我正在测试的网站，但没有做任何其他事情，Firefox浏览器完美地运行测试（在测试结束时打印消息）告诉我它通过了，至少应该已经通过了。当套件运行完毕后，测试告诉我chrome已经通过（它没有）并且Firefox抛出了一个未找到异常的元素。我知道我的问题与保持我的线程不会越过，但这是我第一次设置这样的东西，我不知道如何调试它。

的testng.xml

Base.java

public class Base {

    public WebDriver driver = null;

    public WebDriver getDriver(String browserName, String nodeURL) throws MalformedURLException {

        DesiredCapabilities caps = null;

        if (browserName.equals("firefox")) {
            caps = DesiredCapabilities.firefox();
        } else if (browserName.equals("chrome")) {
            caps = DesiredCapabilities.chrome();
        }

        caps.setBrowserName(browserName);
        caps.setPlatform(Platform.VISTA);
        driver = new RemoteWebDriver(new URL(nodeURL), caps);

        return driver;
    }

TestBase.java

public class TestBase extends Base {


    @BeforeMethod
    @Parameters({"browserName", "nodeURL"})
    public void beforeTest(String browserName, String nodeURL) throws MalformedURLException {
        Base b = new Base();
        driver = b.getDriver(browserName, nodeURL);
        //driver = b.getLocalDriver();      
    }

    @AfterMethod
    public void afterTest() {       
        driver.quit();
    }   
}

LoginTest.java

public class LoginTest extends TestBase {

    @Test
    public void one() throws IOException {
        driver.get("http://company.com");

        EmailModal modal = new EmailModal();
        modal.cancelModal();

        Header header = new Header();
        header.clickSignInLink();

        System.out.println("Page Title is: " + driver.getTitle());
    }

}

EmailModalPage.java

public class EmailModalPage extends Base {
    public WebElement emailModalCancelButton() {
        return driver.findElement(By.cssSelector("a[class='js-closeLayer closeLayer fr'")) ;  
        // ^^^ Line 11, where the error was thrown
    }
}

EmailModal.java

public class EmailModal extends EmailModalPage {
    public void cancelModal() {
        emailModalCancelButton().click();
    }

这是删除static关键字时抛出的错误：

java.lang.NullPointerException
    at com.company.automation.ecom.pages.EmailModalPage.subscribeToEmailModal(EmailModal_.java:11)

并行使用TestNG运行Selenium测试会导致错误
