Question

我使用在远程docker网格上运行的webdriver运行测试。有时，虽然测试已经抓住了浏览器并且在运行过程中，但转发请求的连接失败（可能在集线器和节点之间），然后由于此而导致测试失败。有没有优雅的方式，我可以在测试中处理这样的错误并重试运行测试。我知道网格问题是这里的主要问题，但这个问题必须单独处理，但我很想知道如何在测试中处理这些错误。我已经提到了我的测试和驱动程序工厂的样子。任何帮助将不胜感激。我还在底部提到了网格中的错误，由于哪个测试失败了，但是这个错误我并不关心，因为我正在单独处理该网格问题。

@BeforeClass(alwaysRun = true)
public void setUpBeforeClass(){
instantiateDriverAndpages(browserName,browserVersion,platform) // grab remote webdriver instance
}

@Test
public void test1(retryAnalyzer = TestBase.class){
// all tests here
// in this part sometimes, test fails because of connection issue with grid
}

public void instantiateDriverAndpages(String browserName, String browserVersion, String platform) throws Exception {

    driverFactory = new DriverFactory();
    driver = driverFactory.get(browserName, browserVersion);

    if (driver == null) {

        throw new WebDriverException("Failed to load Remote WebDriver Instances");
    }
    dr = (RemoteWebDriver) driver;
   }

@AfterClass(alwaysRun = true)
public void afterClass() {
    if (driver != null) {
        driver.quit();
    }
    if (dr != null) {
        dr.quit();
    }
}

@AfterMethod(alwaysRun = true)
public void afterTest(ITestResult result) throws Exception {
    methodName = result.getName();

    if (!result.isSuccess()) {
        log.error("Test  Failed in method " + methodName);
    }

    log.info("After method  {}", methodName);
}

在Driverfactory类中的某个地方

    public WebDriver get(String browserName, String browserVersion, String platform) throws MalformedURLException, InterruptedException {
        // Set common webdriver properties
        des = new DesiredCapabilities();
            threadDriver = new ThreadLocal<RemoteWebDriver>();    
            des.setPlatform(Platform.valueOf(platform));
            des.setVersion(browserVersion);
            log.info("Setting cross browser run");

            // set the desired capabilities per browser
            switch (BrowserName.valueOf(browserName)) {
                case FIREFOX:
                    //set firefox cap
                    log.info("Setting FIREFOX browser");
                    break;
                case IE:
                    des.setBrowserName(BrowserType.IE);
                    log.info("Setting IE browser");
                    break;
                case CHROME:
                    des.setBrowserName(BrowserType.CHROME);
                    log.info("Setting CHROME browser");
                    break;

            }

            String seleniumIP="someIp";
            remoteWebDriver = new RemoteWebDriver(new URL(seleniumIP), des);
            remoteWebDriver.setFileDetector(new LocalFileDetector());
            driver = remoteWebDriver;
            threadDriver.set((RemoteWebDriver) driver);
              return getDriver();
        }


    }

由于哪个测试失败导致网格出错：
