Selenium - 执行 selenium.stop() 时出现异常

Question

我正在使用 Selenium 进行 Web 应用程序测试。完成所有测试后，执行“selenium.stop()”命令时出现以下异常：

这是执行 stop() 命令的代码

public class orkut extends SeleneseTestCase {
public void setUp() throws Exception {
    setUp("https://www.google.com/");
}

    public void testOrkut() throws Exception {
              Parser parser = new Parser();
              try {
                  .......
                  .......
                  .......
              }catch(Exception ex) {   
              }finally {
                  parser.closeConnection();
                  selenium.shutDownSeleniumServer();
              }
    }

     public static Test suite() {
    return new TestSuite(orkut.class);
}
public void tearDown(){
    selenium.stop();
}
public static void main(String args[]) {
    junit.textui.TestRunner.run(suite());
}

}

Answer 1

看起来您在关闭浏览器会话的命令之前关闭了 Selenium 服务器。尝试使用 selenium.shutDownSeleniumServer() 注释掉该行；

Answer 2

我遇到了同样的错误。我清除了我的 jar 文件并重新添加它们，异常消失了。
