java - NoSuchSessionException 会话 ID 为空。调用 quit() 后使用 WebDriver？并行运行 java 测试时

问题描述

获取 NoSuchSessionException 会话 ID 为空。调用 quit() 后使用 WebDriver？通过跨浏览器并行运行 java 测试时出错。

测试执行看起来不错，但最后出现了 NoSuchSessionException 错误。我知道驱动程序应该在某个地方初始化，但不清楚如何做到这一点。

项目信息：selenium WD、java、testng、maven。测试正在 jenkins 上构建并在 saucelabs 上运行。

主类看起来像：

  public class NewCustomerReg extends RemoteTestBase {
  @Test (dataProvider = "browsers")

  public void RegisterNewUser (String browser, String version, String os, 
  Method method) throws Exception {

    this.createRemoteDriver(browser, version, os, method.getName());
    Application app = new Application(driver);

    app.homePage().homePageDisplayed();
    Log.info("Validate Home Page");

    app.homePage().registerToOrder.click();
    Log.info("Click Register To Order link on the home page");

    app.registerToOrderPage().registerAsNewCustomer.click();
    Log.info("Click on Register As New Customer button");

    driver.close();
 }

由主类扩展的 RemoteTestBase：

public class RemoteTestBase {

public WebDriver driver;
private static String baseUrl;
ConfigFileReader configRead;
protected PropertyLoader propertyRead;
public Logger Log = Logger.getLogger(BasicTest_Local.class.getName());
private static final String SAUCE_ACCESS_KEY = 
System.getenv("SAUCE_ACCESS_KEY");
private static final String SAUCE_USERNAME = System.getenv("SAUCE_USERNAME");

@BeforeMethod

@DataProvider(name = "browsers", parallel = true)
public static Object[][] sauceBrowserDataProvider(Method testMethod) throws 
JSONException {

    String browsersJSONArrayString  = 
    System.getenv("SAUCE_ONDEMAND_BROWSERS");
    System.out.println(browsersJSONArrayString);
    JSONArray browsersJSONArrayObj = new JSONArray(browsersJSONArrayString);

    Object[][] browserObjArray = new Object[browsersJSONArrayObj.length()] 
    [3];
    for (int i=0; i < browsersJSONArrayObj.length(); i++) {
        JSONObject browserObj = 
    (JSONObject)browsersJSONArrayObj.getJSONObject(i);
        browserObjArray[i] = new Object[]{browserObj.getString("browser"), 
    browserObj.getString("browser-version"), browserObj.getString("os")};
    }
    return browserObjArray;
   }

   void createRemoteDriver(String browser, String version, String os, String 
   methodName) throws Exception {

    DesiredCapabilities capabilities = new DesiredCapabilities();
    Class<? extends RemoteTestBase> SLclass = this.getClass();
    capabilities.setCapability("browserName", browser);
    if (version != null) {
        capabilities.setCapability("browser-version", version);
    }
    capabilities.setCapability("platform", os);
    capabilities.setCapability("name", SLclass.getSimpleName());
    capabilities.setCapability("tunnelIdentifier", "hdsupply");


    driver = (new RemoteWebDriver(new URL("http://" + SAUCE_USERNAME + ":" + 
    SAUCE_ACCESS_KEY + "@ondemand.saucelabs.com:80/wd/hub"), capabilities));

    randomuser = new RandomDataSelect();
    configRead = new ConfigFileReader();
    propertyRead = new PropertyLoader();
    baseUrl = propertyRead.getProperty("site.url");
    getURL();
}



private void getURL () {

    driver.get(baseUrl);
    driver.manage().timeouts().implicitlyWait(40, TimeUnit.SECONDS);
    this.annotate("Visiting page..." + driver.toString());


}

private void printSessionId() {

    String message = String.format("SauceOnDemandSessionID=%1$s job- 
    name=%2$s",
            (((RemoteWebDriver) driver).getSessionId()).toString(), "some job 
    name");
    System.out.println(message);
}



@AfterMethod(description = "Throw the test execution results into saucelabs")
public void tearDown(ITestResult result) throws Exception {

    ((JavascriptExecutor) driver).executeScript("sauce:job-result=" + 
 (result.isSuccess() ? "passed" : "failed"));
    printSessionId();
    driver.quit();
}
void annotate(String text)
{
    ((JavascriptExecutor) driver).executeScript("sauce:context=" + text);
}
}
