【问题描述】：
我正在尝试通过 TestNGCucumberRunner 并行运行自动化测试，我的问题是我使用 Manager 类中的静态 get 方法实例化了我的 PageObjects，因为其中的驱动程序是静态的。我很确定这是并行执行的问题。如何以线程安全的方式检索驱动程序？
感谢任何帮助。
编辑： 我当前的驱动程序类：
public class LocalDriverManager {
private static ThreadLocal<AppiumDriver> localDriver = new ThreadLocal<>();
public static AppiumDriver getDriver() {
return localDriver.get();
}
static void setDriver(AppiumDriver driver) {
localDriver.set(driver);
}
public static ThreadLocal<AppiumDriver> getLocalDriver() {
return localDriver;
}
}
这里我在另一个类中初始化驱动：
这是我初始化驱动程序并在另一个类中设置 ThreadLocal 的方式：
if (capabilities.getPlatform().is(Platform.IOS)) {
driver = new IOSDriver<MobileElement>(new URL(urlStart + appiumServer.getPort() + "/wd/hub"),
capabilities);
} else {
driver = new AndroidDriver<MobileElement>(
new URL(urlStart + appiumServer.getPort() + "/wd/hub"),
capabilities);
}
LocalDriverManager.setDriver(driver);
当我在另一个类中设置我的驱动程序时，我设置了 localDriver 变量
public BasePage(AppiumDriver driver, WebDriverWait wait) {
this.driver = driver;
this.wait = wait;
PageFactory.initElements(new AppiumFieldDecorator(driver, Duration.ofSeconds(10)), this);
}
我现在收到此异常：

【问题讨论】：
-
创建一个单独的驱动管理器类并将驱动对象声明为 ThreadLocal。您将不得不使用 setter/getter 方法来存储您的线程驱动程序并在需要时检索它。

@Sureshmani 我尝试了这种方法，但它对我不起作用。还是应该是一个单独的类，只包含驱动程序？
