java+selenium自动化实践

git+java+selenium+testng +maven+idea

1、git之代码维护（下载、分支切换、上传）

下载命令 "git clone git@github.com:Luna0715/learnmaven.git"
git branch -a 列出所有分支
git branch 查看本地分支
创建分支：git branch <name>
创建+切换分支：git checkout -b <name>
git checkout -b develop origin/develop 切换到develop分支
git branch 验证一下，已经切换到develop分支
再切换回master： git checkout master git branch

git remote add origin git@github.com:Luna0715/GodLikeCourse.git
使用命令 git add . 提交新文件(new)和被修改(modified)文件，不包括被删除(deleted)文件到缓存区
git commit -am "修改代码" 用于提交跟踪过的文件 
git push 将本地分支的更新，推送到远程主机
git push --set-upstream origin develop推送远程不存在的本地分支

更新项目：

1.加一个线上主干git remote add upstream git@github.com:QA/GodLikeCourse.git

2.从主干拉取代码 git pull upstream master

git status
git stash

2、引用testng

import org.testng.annotations.Test;

方法前加注释@Test

3、调试

定位到要断点的源代码行，在源代码所在行前面，单击一下鼠标左键，设置一个断点，以DEBUG的模式运行项目

4、元素定位   

xpath常用符号说明：

/表示绝对路径，绝对路径是指从根目录开始

//表示相对路径

.表示当前层

..表示上一层

*表示通配符

@表示属性

[]属性的判断条件表达式

1）driver.findElement(By.linkText("个人中心"))

2）driver.findElement(By.id("mobile1")).sendKeys("13111111111");

3）WebElement confirm = driver.findElement(By.className("confirm-btn"));

4）public static String getusername;

getusername = driver.findElement(By.xpath(".//*[@class='option']/li[1]/a")).getText();

WebElement fenqi = driver.findElement(By.xpath("//span[text()='分期']"));

WebElement CheTu = driver.findElement(By.xpath(".//*[@class='carlist']/ul/li[1]"));

By.xpath(".//*[@class='pop-up-layer' and @style='display: block;']")

5）通过定位到的元素继续定位元素

WebElement productlist = driver.findElement(By.id("FirstPageProductList1"));
List<WebElement> products = productlist.findElements(By.className("list-header-ctr"));
System.out.println("product数量"+products.size());
getText = products.get(0).findElements(By.className("company-name")).get(0).getText();
for (WebElement ele : products) {

    sleep(2);
    getText = ele.findElements(By.className("company-name")).get(0).getText();
    System.out.println("套餐名称是:" + getText);
}

List<WebElement> SeeInof = productlist.findElements(By.className("col-black"));
SeeInof.get(0).click();
5、页面切换
#不关闭旧窗口

public static void removeHandles(WebDriver driver){
    //获取当前页面句柄
    String handle = driver.getWindowHandle();
    // 获取所有页面的句柄，并循环判断不是当前的句柄
    for (String handles : driver.getWindowHandles()) {
        if (handles.equals(handle))
            continue;
        driver.switchTo().window(handles);
    }
}

#关闭旧窗口

    public static void removeHandles(WebDriver driver){
    //获取win窗口
    try {
        String [] handles = new String[driver.getWindowHandles().size()];//定义一个空数组，数组大小是打开窗口的数量
        driver.getWindowHandles().toArray(handles);//将获取到的句柄集合转换为数组
        //here
        //driver.switchTo().window(handles[1]);
        sleep(2);
        //切换到旧窗口
        WebDriver handle2 = driver.switchTo().window(handles[0]);
        sleep(2);
        //关闭旧窗口
        handle2.close();
        sleep(2);
        //切换到新窗口
        driver.switchTo().window(handles[1]);
        sleep(2);
    } catch (ArrayIndexOutOfBoundsException e) {
        // TODO: handle exception
        System.out.println("浏览器切换窗口异常" + e);
    }}

6、截图
1）
if(isElementExist(driver, By.xpath("//*[@id="list"]/aside[1]/div[1]/div[2]/aside[1]/a/img")) ==true ){

    System.out.println("车图元素存在！");
}else{
    System.out.println("车图元素未找到，失败图片：" + picturePath);
    screenShot(picturePath,driver);//调用失败截图功能；
}

public static void screenShot(String path,WebDriver driver){
    //将当前窗口截屏，获得一个File的图片文件对象；
    File screenFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    //将图片文件对象，保存到指定的路径path里,例如D盘的某个文件夹下。
    try {
        File file = new File(path);   //在指定路径中，创建一个空白的图片文件
        FileUtils.copyFile(screenFile,file);//将窗口截屏文件，保存到刚刚创建的空白文件里
    } catch (IOException e) {
        e.printStackTrace();
    }
}

2）

try{
    driver.findElement(By.className("logo-sv"));
}catch(Exception e) {
    e.printStackTrace();
    String tpath="D:\screenshots\"+getScreen(driver)+".jpg";
    System.out.println("logo元素未找到，失败图片：" +tpath);//调用失败截图功能；
}

public static String getScreen(WebDriver driver) throws Exception{
    Date dt = new Date();
    SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
    File screenshot=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    FileUtils.copyFile(screenshot,new File("D:\screenshots\"+sdf.format(dt)+".png"));
    return sdf.format(dt);
}

7、校验

1）
if (getusername.equals("135****7172")){
    System.out.println("登录成功");
}
else{
    System.out.println("登录失败");
}

2）
if(isElementExist(driver, By.xpath(".//*[@class='carlist']/ul/li[1]/div[1]")) == true){
    System.out.println("第一个车图元素存在！");
}else{
    System.out.println("第一个车图元素未找到！");
}

public static boolean isElementExist(WebDriver driver, By by) {
    try {
        driver.findElement(by);
        return true;
    } catch(NoSuchElementException e) {
        return false;
    }
}

8、用JS方法将滚动条定位到某个元素

WebElement CheTu = driver.findElement(By.xpath(".//*[@class='carlist']/ul/li[1]"));
public static void executeJS(WebDriver driver,WebElement arg) {

    //用JS方法将滚动条定位到xx元素,其中auguments[0]就代表element
    ((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView();",arg);
}

9、线程休眠

public static  void sleep(double d) {
    try {
        d *= 1000;
        Thread.sleep((int)d);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}
10、捕获异常

try {

} catch (InterruptedException e) {
    e.printStackTrace();
}

11、断言

assert getPackagename.contains(getText);
assert driver.getTitle().equals("XXXXXX");

12、初始化

//将浏览器的驱动程序位置设定为系统属性值:webdriver.chrome.driver
System.setProperty("webdriver.chrome.driver", "D:/selenium/chromedriver.exe");
//启动浏览器
WebDriver driver = new ChromeDriver();
//打开网址
driver.get("https://www.xxxxxx.com/");
//窗口最大化
driver.manage().window().maximize();
// 获取 网页的 title
System.out.println("The testing page title is: " + driver.getTitle());

13、需要引入的包

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

import java.util.List;
import java.io.File;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import java.util.Date;
