最近在UI自动化时遇到了，上一步成功操作后没有响应的情况（动画加载和浏览器加载导致实际没有问题），导致下一步无法成功操作，所有想在尝试2次操作后再次进行上一步操作解决这种情况导致的错误（其实是不想每一次有问题都要手动加线程沉睡）
1.java应用程序，暂停/开始按钮
import java.awt.Dimension;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import org.openqa.selenium.WebDriver;
import base_operation.Login; @SuppressWarnings({"static-access","deprecation"})
public class Common_method {public void paused_start(Element_operation element_operation){ JFrame frame = new JFrame("开始/暂停");//新建一个窗体，窗体的标题是""中的内容，
frame.setSize(200,100);//设置窗体的尺寸、Dimension frameSize=frame.getSize();
Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();//获取屏幕尺寸对象
//frame.setLocation((screenSize.width-frame.getWidth())/2, (screenSize.height-frame.getHeight())/2);//设置窗体坐标
frame.setLocation(screenSize.width-220, screenSize.height-150);
frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE); //定义了点击关闭按钮的作用；
frame.setAlwaysOnTop(true);//把应用置于最前
frame.setVisible(true);//注意这一步一定要调用，使得这个窗体可见，false是不可见；
//JPanel panel = new JPanel();//Jpanel 是面板容器类，包含在swing中；
JButton jButton1 = new JButton("暂停");//定义一个button
frame.add(jButton1);
jButton1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
if(element_operation.get_paused_start()==0){
element_operation.paused();
System.out.println("暂停--------------------------------------------------");
jButton1.setText("开始");
}else if(element_operation.get_paused_start()==1){
element_operation.start();
System.out.println("开始--------------------------------------------------");
jButton1.setText("暂停");
}
}
});
} }

使用示例：

private Channel channel;

Common_method common_method = new Common_method();
common_method.paused_start(element_operation);//开始/暂停应用
WebDriver.manage().window().maximize();
WebDriver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
@After
public void tearDown() throws Exception {
try {
Thread.sleep(1000);
} catch (Exception e) {
// TODO: handle exception
}
WebDriver.quit();
}
@Test
public void test() {
WebDriver.get("http://www.baidu.com");
element_operation.Web_Wait_Element(WebDriver, input1, element_operation.sendKeys, "QQ");
element_operation.Web_Wait_Element(WebDriver, input1, element_operation.getText, "");
String text = element_operation.get_return_text();
System.out.println(text); element_operation.Web_Wait_Element(WebDriver, button1, element_operation.click, "");
}
}
