Question

启动层初始化期间发生错误 java.lang.module.FindException：无法派生C：\ Users \ admin \ eclipse-workspace \ Testing \ lib \ selenium-server-standalone.jar

的模块描述符

Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class org.eclipse.jetty.http.Http1FieldPreEncoder not in module

package Testing;

import com.thoughtworks.selenium.DefaultSelenium;
import com.thoughtworks.selenium.Selenium;

public class Testing {

    public static void main(String[] args) throws InterruptedException
    {
        Selenium selenium= new DefaultSelenium("localhost",4444,"firefox","http://www.calculator.net");
        selenium.start();
        selenium.open("/");
        selenium.windowMaximize();
        selenium.click("xpath=.//*[@id=''hl3']/li[3]/a"); 
        Thread.sleep(4000);
        selenium.focus("id=cpar1");
         selenium.type("css=input[id=\"cpar1\"]", "10"); 
        selenium.focus("id=cpar2"); 
         selenium.type("css=input[id=\"cpar2\"]", "50"); 
         (selenium).click("xpath=.//*[@id='content']/table[1]/tbody/tr[2]/td/input[2]"); 
         // verify if the result is 5
         Thread.sleep(4000);
         String result = selenium.getText("xpath=.//*[@id='content']/p[2]/font/b");
         //String result = selenium.getValue("xpath=.//*[@id='cpar3']");
         System.out.println("Result:"+result);

         if (result.equals("5")/*== "5"*/){
            System.out.println("Pass");
         }
         else{
            System.out.println("Fail");
         }

    }

}

Answer 1

1. 我建议重新考虑使用Selenium Remote Control，因为它已不再受支持，已经过时了，目前Selenium Java客户端的稳定版本是3.141.59，它提供了WebDriver API，这是{截至目前为止，{3}}。

2. 一旦实现了选项1，就摆脱了W3C Standard，因为它是某种形式的性能Thread.sleep()，请改用anti-pattern，签出Explicit Wait以获得全面的说明和代码示例。

3. 最好使用诸如How to use Selenium to test web applications using AJAX technology之类的依赖项管理解决方案，该解决方案将自动检测并下载您的项目Apache Maven。一个相关的pom.xml文件将类似于：
