我用testng的并行测试，其中一个浏览器运行，测试成功。其他浏览器打开但无法继续

Question

**我的 xml 是这样的。**在所有代码不并行时完全准确地工作

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

我的 ThreadLocal 驱动程序类是这样的。 在所有代码不并行时完全准确地工作

package Utils;

import io.github.bonigarcia.wdm.WebDriverManager;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.edge.EdgeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.safari.SafariDriver;

import static Utils.Browsers.CHROME;

public class ThreatDriver {
    //private static WebDriver driver;
    private static ThreadLocal<WebDriver> drivers = new ThreadLocal<>();

    public static WebDriver getDriver(){
        return getDriver(Browsers.CHROME);
    }

    public static WebDriver getDriver(Browsers browser){
       
        if (drivers.get() == null){
            switch (browser){
                case FIREFOX:
                    WebDriverManager.firefoxdriver().setup();
                    //driver = new FirefoxDriver();
                    drivers.set(new FirefoxDriver());
                    break;
                case EDGE:
                    WebDriverManager.edgedriver().setup();
                    drivers.set(new EdgeDriver());
                    break;
                default:
                    WebDriverManager.chromedriver().setup();
                    ChromeOptions options = new ChromeOptions();
                    options.addArguments("--remote-allow-origins=*");
                    drivers.set(new ChromeDriver(options));
                    break;
            }
        }
        return drivers.get();
    }

    public static void quitDriver(){
        if (drivers.get() != null) {
            drivers.get().quit();
            drivers.set(null);
        }
    }

}

我的基础测试是这样的。 在所有代码不平行时完全准确地工作

public class BaseTest {

static WebDriver driver;
static WebDriverWait wait;
    @BeforeTest
    @Parameters("browser")
    public void setup(@Optional String browser){
        if (driver==null) {
            driver=ThreatDriver.getDriver(Browsers.valueOf(browser.toUpperCase()));
        }
        driver.manage().window().maximize();
        wait=new WebDriverWait(driver, Duration.ofMillis(10_000));
        Element.driver=driver;
        Element.wait=wait;
    }

    @AfterTest
    public void tearDown() {
       driver.quit();
    }
}

我的测试是这样的。

public class Tests extends BaseTest {


    @Test
    public void test1() throws InterruptedException {
        _open(URL);
        Thread.sleep(2000);
        waitFor(driver,Conditions.urlContains,null,"login");
        $(xpath(ALL_INPUT,"Username")).sendKeys("Admin");
        $(xpath(ALL_INPUT,"Password")).sendKeys("admin123").submit();
        waitFor(driver,Conditions.urlContains,null,"index");
        $(xpath(ALL_SPAN_2,"Admin")).click();

    }

}

有时，当我在运行的浏览器中执行 sendkeys 时，我看到它发送了一个变量两次。这就像并行运行，但在一个浏览器中有两个驱动程序。
