selenium-java，解决一些加了显性等待和隐性等待都不好使的情况，以及给UI自动化加上暂停功能

Posted 2020-10-06

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：

public class Guest_Share_Test {
    
    private WebDriver WebDriver;
    private Element_operation element_operation;
    private Channel channel;

    private By input1 = By.id("kw");
    private By button1 = By.id("su");

    
    @Before
    public void setUp() throws Exception {
        element_operation = new Element_operation();
        System.setProperty("webdriver.chrome.driver","D:\\Configuration\\chromedriver.exe");//这一步必不可少  
        WebDriver = new ChromeDriver();
        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, ""); 

    }
