Java Firefox Webdriver实例'；打开两个窗口'；而不仅仅是'；x1窗口'；

Firefox Webdriver实例“打开x2个窗口”，而不仅仅是“x1窗口”

有什么想法吗

try {
    // Load the driver selected by user
    Properties p = new Properties();
    FileInputStream fi = new FileInputStream(Constant.CONFIG_PROPERTIES_DIRECTORY);
    p.load(fi);

    String browserName = p.getProperty("browser");
    switch (browserName) {
        case "firefox":
            if (null == webdriver) {
                System.setProperty("webdriver.gecko.driver",Constant.GECKO_DRIVER_DIRECTORY );
                webdriver = new FirefoxDriver(DesiredCapabilities.firefox());
                webdriver = new FirefoxDriver();
            }
            break;
        case "chrome":
            if (null == webdriver) {
                System.setProperty("webdriver.chrome.driver", Constant.CHROME_DRIVER_DIRECTORY );
                webdriver = new ChromeDriver();
            }

您调用

新FirefoxDriver（）

两次

完全删除此行：

webdriver = new FirefoxDriver(DesiredCapabilities.firefox());

在脚本的开头放置一个断点并运行它。现在，逐行检查代码，看看哪一行创建了另一个实例。
