Selenium网格并行运行测试

Question

目前，我有一个Selenium网格设置，有1个本地集线器和2个本地节点。集线器能够分发并行运行的测试，并将其分发到节点。我在并行运行测试。

public abstract class BaseTest 
   {    
            String                      testFolder;
            String                      testName;
            protected String            envName;        
            protected Configuration     config;
            protected String            host;
            protected RemoteWebDriver   driver;
            protected String            proxy;
            protected SomeData      someData;
            protected SomeController someController;

            public BaseTest() {
              }

            public BaseTest( String testFolder, String testName) 
            {   
                this.testFolder         = testFolder;
                this.testName           = testName;
                this.envName            = System.getProperty("config");
                this.proxy              = System.getProperty("proxy");
                config = this.envName;
            }

            @BeforeMethod 
            public void startTest(Method testMethod) {
                LOG.info("Starting test: " + testMethod.getName());
                try {
                this.someData       = new SomeData();
                this.driver             = WebDriverSetup.getDriver();
                this.someController = new someController(this.driver, this.someData);
                driver.navigate().to("https://" + this.host);
                } catch (MalformedURLException e) {
                    System.out.println("MalformedURLException");
                }
            }
            @AfterMethod
            public void closeWindow() {
                driver.close();
                driver.quit();
            }
        }

        public class WebDriverSetup {

            public static RemoteWebDriver getDriver() throws MalformedURLException{

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

                DesiredCapabilities capabilities = DesiredCapabilities.firefox();
                capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
                String proxy = System.getProperty("proxy");

                if (proxy != null && !proxy.isEmpty()) {
                    System.out.println("Using proxy: " + proxy);
                    capabilities.setCapability(CapabilityType.PROXY, proxy);
                }

                try {
                    remoteWebDriver = new ThreadLocal<RemoteWebDriver>();
                    remoteWebDriver.set(new RemoteWebDriver(new URL(SELENIUM_HUB_URL),
                            capabilities));
                } catch (MalformedURLException e) {
                    System.out.println("Tackle Issue with RemoteDriverSetup");
                }

                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();
            }
        }

        </classes>
    </test>
</suite>

public class Tests extends BaseTest {

@Parameters({"testName", "env" })
public Tests( @Optional String testName, @Optional String env ) {
    super( null, testName, null, env );
}

@BeforeMethod
public void setup() throws Exception {
    //setSomeData
}   

public void test1() throws Exception {  

use driver from super
use someData from super
use someController is using the driver from super
}

public void test2() throws Exception {  

use driver from super
use someData from super
use someController is using the driver from super
}

在运行这些测试时，我得到以下错误

有人知道吗？

提前感谢！

不要在基类中设置driver，根本没有driver属性。同一实例正被不同的threadlocal驱动程序重写。

任何时候要运行测试，都可以在测试方法本身和after/before方法中引用WebDriversetup.getDriver（）。
