Selenium脚本转化Java代码

Selenium录制的脚本可以转换Java JUnit单元测试，可以使用Java项目管理工具Maven统一运行，从Selenium脚本中导出Java代码，按照如下步骤

使用Java运行Selenium脚本，使用Chome导出Java脚本必须下载Chome驱动，如果使用Firefix导出的Java脚本必须下载Firefix驱动。

Firefix驱动

导出的Java代码，需要添加到Java Maven项目中，并添加所需依赖

<dependency>
    	      <groupId>junit</groupId>
    	      <artifactId>junit</artifactId>
    	      <version>4.11</version>
    	      <scope>test</scope>
    	    </dependency>
    	    
            <dependency>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-java</artifactId>
                <version>3.5.3</version>
            </dependency>

修改Java脚本，需要设定Firefox驱动所在目录  
System.setProperty(“webdriver.firefox.driver”, “D:\\soft\\Tester\\driver\\geckodriver.exe”);

package com.hk.sec;
    
    import org.junit.Test;
    import org.junit.Before;
    import org.junit.After;
    import static org.junit.Assert.*;
    import static org.hamcrest.CoreMatchers.is;
    import static org.hamcrest.core.IsNot.not;
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.firefox.FirefoxDriver;
    import org.openqa.selenium.chrome.ChromeDriver;
    import org.openqa.selenium.remote.RemoteWebDriver;
    import org.openqa.selenium.remote.DesiredCapabilities;
    import org.openqa.selenium.Dimension;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.interactions.Actions;
    import org.openqa.selenium.support.ui.ExpectedConditions;
    import org.openqa.selenium.support.ui.WebDriverWait;
    import org.openqa.selenium.JavascriptExecutor;
    import org.openqa.selenium.Alert;
    import org.openqa.selenium.Keys;
    import java.util.*;
    import java.net.MalformedURLException;
    import java.net.URL;
    
    public class LoginTest { 
      private WebDriver driver;
      private Map<String, Object> vars;
      JavascriptExecutor js;
      
      @Before
      public void setUp() { 
    	System.setProperty("webdriver.firefox.driver", "D:\\soft\\Tester\\driver\\geckodriver.exe");
        driver = new FirefoxDriver();
        js = (JavascriptExecutor) driver;
        vars = new HashMap<String, Object>();
        
      }
      
      @After
      public void tearDown() { 
        driver.quit();
      }
      
      @Test
      public void login() { 
        driver.get("http://localhost:8080/");
        driver.manage().window().setSize(new Dimension(1768, 1200));
        driver.findElement(By.cssSelector(".el-form-item:nth-child(1) .el-input__inner")).sendKeys("gf:gfadmin");
        driver.findElement(By.cssSelector(".el-form-item:nth-child(2) .el-input__inner")).sendKeys("1");
        driver.findElement(By.cssSelector(".sys-login")).click();
        vars.put("vcode", driver.findElement(By.cssSelector(".el-form-item:nth-child(1) .el-input__inner")).getAttribute("value"));
        vars.put("vcode", js.executeScript("var start=document.cookie.indexOf(\'vcode=\')+\'vcode=\'.length; var end=document.cookie.indexOf(\';\',start); if(end == -1) return document.cookie.substring(start); else return document.cookie.substring(start, end);"));
        driver.findElement(By.cssSelector(".el-form-item:nth-child(3) .el-input__inner")).sendKeys(" vars.get(\"vcode\").toString()");
        driver.findElement(By.linkText("登录")).click();
      }
    }

运行时可能遇到异常  
java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)V  
通常是因为guava版本问题

<groupId>com.google.guava</groupId>
    			      <artifactId>guava</artifactId>

需要使用正确guava版本，selenium-java会引入正确的guava版本，如果其他Jar引入guava版本，需要排除它

<groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-java</artifactId>
                <version>3.4.0</version>

例如：  
sharding-jdbc-core也会引入guava，必须排除它

<dependency>
    		    <groupId>org.apache.shardingsphere</groupId>
    		    <artifactId>sharding-jdbc-core</artifactId>
    		    <version>4.1.0</version>
    	        <exclusions>
    	            <exclusion>
    			      <groupId>com.google.guava</groupId>
    			      <artifactId>guava</artifactId>
    	            </exclusion>
    	        </exclusions>
    		</dependency>
