黄瓜并行测试给出奇怪的结果

Question

我正在尝试在并行浏览器中运行我的黄瓜项目（两个运行器类），但结果很奇怪。当我执行mvn verify 时，首先它将按顺序运行每个跑步者类。由于以下错误，第一个将通过，第二个将失败 -

org.openqa.selenium.NoSuchSessionException: Session ID is null. Using WebDriver after calling quit()?

然后，它将并行运行两个运行器类（就像我想要的那样），一切都会顺利通过。 maven 会报告 Build Success。

我没有在 @Before 注释中初始化 webdriver。相反，我在我的步骤定义类中使用 cucumber-picocontainer 依赖注入。我尝试在 @After 注释中交换 driver.close() 和 driver.quit() ，但这并没有改变结果。请在下面找到一些代码 sn-ps，然后是我的 POM。非常感谢。

public class GivenSteps {

    WebDriver driver;
    CustomWaits waits;

    public GivenSteps(DependencyInjection dependencyInjection) {
        this.driver = dependencyInjection.getDriver();
        this.waits = dependencyInjection.getWaits();
    }

挂钩 -

    public class Hooks {

        WebDriver driver;

        public Hooks(DependencyInjection dependencyInjection) {
            this.driver = dependencyInjection.getDriver();
        }

        @Before("@setup")
        public void setUp() {

            driver.manage().deleteAllCookies();
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
            driver.manage().timeouts().pageLoadTimeout(20, TimeUnit.SECONDS);

        }
         @After("@destroy")
         public void tearDown() throws Throwable {
          //driver.close();
            driver.quit();
    }

依赖注入 -

public class DependencyInjection {

    private static String browserType = Settings.BROWSER.getValue();
    private static WebDriver driver = null;
    private static CustomWaits waits = null;

    public WebDriver getDriver() {
        if (driver == null) {
            driver = utilities.DriverFactory.createDriver(browserType);
        }
        return driver;
    }

Answer 1

我不得不在我的 POM.xml 中注释掉该部分 -> maven-surefire-plugin 因为现在我只使用 maven-failsafe-plugin

最初我的 POM 中都处于活动状态，因此它们都是按顺序运行的。
