如何为特定测试类重置serenity.property重新启动浏览器

import net.thucydides.core.annotations.Before;
import net.thucydides.core.configuration.Configuration;
import net.thucydides.core.configuration.EnvironmentVariables;

public class MyTestClass {

    @Before
    public void resetPropertiesAndRestartBrowser() throws IOException {
        // 获取serenity.properties文件的路径
        String propertiesFilePath = "src/test/resources/serenity.properties";

        // 创建一个新的Properties对象
        Properties properties = new Properties();

        // 加载默认的serenity.properties文件
        FileInputStream inputStream = new FileInputStream(propertiesFilePath);
        properties.load(inputStream);

        // 修改特定的配置项
        properties.setProperty("webdriver.driver", "chrome");

        // 关闭当前的浏览器会话
        Serenity.restartBrowser();

        // 重新启动浏览器会话
        Configuration configuration = new SystemPropertiesConfiguration(new EnvironmentVariables(properties));
        Serenity.initialize(configuration);
    }

    // 其他测试方法...
