TestNG监听器,如何让测试使用单例

我们使用TestNG监听器特性在外部工具中报告测试结果。它工作得很好。

但现在,我们想添加一个由singleton(threadlocalwebdriver)包含的信息。我们的测试活动是并行运行的,所以我们有多个singleton实例。

例如,我们如何在onSuccess方法中获得正确的单例并报告正确的信息?

编辑:代码示例

public class QTestWrapper implements ISuiteListener, ITestListener {
...
    @Override
  public void onTestSuccess(ITestResult result) {
    String sessionId = MyDriver.getSessionId();
    // do my job with this session id
  }
...
}


public final class MyDriver {


  private static final ThreadLocal<MyDriver> MY_DRIVER =
      ThreadLocal.withInitial(MyDriver::buildDriver);

  private WebDriver driver;

  private MyDriver(WebDriver driver) {
    this.driver = driver;
  }

  public static MyDriver getDriver() {
    return MY_DRIVER.get();
  }

  private static MyDriver buildDriver() {
    URL remoteAddress = getHubAddress();
    DesiredCapabilities caps = buildCapabilities();
    WebDriver driver = new RemoteWebDriver(remoteAddress, caps);
    return new MyDriver(driver);
  }

  public static String getSessionId() {
    String sessionId = null;
    MyDriver driver = MY_DRIVER.get();
    if (driver != null && driver.getWrappedDriver() != null) {
      WebDriver wrappedDriver = driver.getWrappedDriver();
      sessionId = ((RemoteWebDriver) wrappedDriver).getSessionId().toString();
    }
    return sessionId;
  }

  public WebDriver getWrappedDriver() {
    return driver;
  }


}

public class TestLogin {

  @AfterMethod(alwaysRun = true)
  public void die() {
    StickyDriver.quit();
  }

  @Test(description = "Check that a user can login with a Manager profile.")
  public void loginAsManager() {
    Actor actor = new Actor("foo");
    String userName = actor.openBrowserAndLogin().getUserName();
    assertThat(userName).isEqualTo("foo");
  }

}


public class Actor {

  private static final Logger LOGGER = LogManager.getLogger();

  private final MyDriver driver;
  private User user;

  public Actor(String userName) {
    user = User.getUser(userName);
    driver = MyDriver.getDriver();
  }


  public Actor(User user) {
    this.user = Objects.requireNonNull(user);
    driver = MyDriver.getDriver();
  }

  public HomePage openBrowserAndLogin() {
    openBrowser();
    return login();
  }

  public HomePage login() {
    LoginPage loginPage = new LoginPage(driver);
    loginPage.getUserNameField().setValue(user.getUsername());
    loginPage.getPasswordField().setValue(user.getPassword());
    return loginPage.login();
  }

  private void openBrowser() {
    String url = EnvironmentHelper.getUrl();
    WebDriver webDriver = driver.getWrappedDriver();
    webDriver.get(url);
    try {
      new WebDriverWait(webDriver, 60).until(AjaxExpectedConditions.callsHaveCompleted());
    } catch (TimeoutException ex) {
      closeBrowser();
      throw ex;
    }
  }

  public void closeBrowser() {
    MyDriver.quit();
  }

}
