杀掉chromedriver.exe进程，防止浪费资源

方法

    public void kill_chromedriver(){
        Runtime runtime=Runtime.getRuntime();
        try{
            System.out.println("kill chromedriver.exe");
            runtime.exec("taskkill /f /im chromedriver.exe");
        }catch(Exception e){
            System.out.println("Error!");
        }
    }

使用例子

    Common_method common_method = new Common_method();
    @After
 public void tearDown() throws Exception {

 try { Thread.sleep(1000); } catch (Exception e) { // TODO: handle exception
 } driver.quit();  common_method.kill_chromedriver(); }
