我使用ThreadLocal来保证线程安全，并使用Maven故障安全和JUnit并行运行测试。我正在运行来自两个特性文件的两个测试来测试并行运行。
但是我总是第一个浏览器是空白的，然后后面的浏览器都很好，测试也通过了，如果我按顺序运行，就没有问题了。

• 钩步 * 类：

public class HookStep {

        @Before()
        public void beginTest() {
            WebDriverFactory.setDriver(Props.getValue("browser.name"));
        }

        @After()
        public void stopTest(Scenario scenario) {
            switch (environment) {

                case "local":
                case "aws": {
                    if (scenario.isFailed()) {
                        Screenshots.Shot shot = new Screenshots(Screenshots.CONTEXT_TEST_FAIL)
                                .takeShot(scenario.getName() + formCounter.getAndIncrement() + "");
                        scenario.embed(shot.getContent(), "image/png", "Error - ");
                    }
                    WebDriverFactory.closeBrowser();
                }
            }
}

Web驱动程序工厂类：

public class WebDriverFactory {

    private static ThreadLocal<WebDriver> driver = new ThreadLocal<>();

    public static synchronized void setDriver(String browser) {

        switch (browser) {
            case "chrome":
                driver = ThreadLocal.withInitial(() -> {
                    WebDriverManager.chromedriver().setup();
                    return new ChromeDriver(BrowserOptions.getChromeOptions());
                });
                prepareBrowser();
                break;

            case "fireFox":
                driver = ThreadLocal.withInitial(() -> {
                    WebDriverManager.firefoxdriver().setup();
                    return new FirefoxDriver(BrowserOptions.getFirefoxOptions());
                });
                break;
            default:
                throw new IllegalStateException("Unexpected value: " + browser);
        }
    }

    private static void prepareBrowser() {
        getDriver().manage().window().maximize();
        getDriver().manage().deleteAllCookies();
        getDriver().manage().timeouts().pageLoadTimeout(15, TimeUnit.SECONDS);
        getDriver().manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
    }

    public static synchronized WebDriver getDriver() {
        return driver.get();
    }

    public static void closeBrowser() {

        getDriver().quit();
    }
}

StepDef类：

public class SampleStepDef {
    private final WorldHelper helper;

    public SampleStepDef(WorldHelper helper) {
        this.helper = helper;
    }

    @Given("I click on the URL")
    public void iClickOnTheURL() {

       helper.getSamplePage().navigateToSite();
    }
}

public class WorldHelper {
    WebDriverFactory webDriverFactory = new WebDriverFactory();

    protected  WebDriver webDriver = webDriverFactory.getDriver();
    private  BasePage basePage;
    private  SamplePage samplePage;

    public SamplePage getSamplePage() {
        if(samplePage != null)
            return samplePage;
        samplePage = PageFactory.initElements(webDriver, SamplePage.class);
        return samplePage;
    }

}

public class SamplePage extends BasePage {

    public SamplePage(WebDriver webDriver) {
        super(webDriver);
    }

    public void navigateToSite() {

        webDriver.get("https://www.bbc.co.uk");
        webDriver.findElement(By.xpath("//a[contains(text(),\'News\')]")).click();
    }
}

public class BasePage extends WorldHelper {

    public BasePage(WebDriver driver) {
        this.webDriver = driver;
    }
}

如何解决此问题？
