• selenium web driver 实现截图功能


    在验证某些关键步骤时,需要截个图来记录一下当时的情况

    Webdriver截图时,需要引入

    import java.io.File;
    import java.io.IOException;
    import org.apache.commons.io.FileUtils;
    import org.openqa.selenium.OutputType;
    import org.openqa.selenium.TakesScreenshot;

    截图方法

    复制代码
    public static void snapshot(TakesScreenshot drivername, String filename)
      {
          // this method will take screen shot ,require two parameters ,one is driver name, another is file name
          
        String currentPath = System.getProperty("user.dir"); //get current work folder
        System.out.println(currentPath);
        File scrFile = drivername.getScreenshotAs(OutputType.FILE);
            // Now you can do whatever you need to do with it, for example copy somewhere
            try {
                System.out.println("save snapshot path is:"+currentPath+"/"+filename);
                FileUtils.copyFile(scrFile, new File(currentPath+"\"+filename));
            } catch (IOException e) {
                // TODO Auto-generated catch block
                System.out.println("Can't save screenshot");
                e.printStackTrace();
            } 
            finally
            {
               
                System.out.println("screen shot finished");
            }
      }
    复制代码

    以下任务:

    1.使用selenium打开百度,截图;

    2.输入selenium关键字,截图;

    3.搜索 并打开 selenium的百度百科,截图;

    具体代码如下:

    复制代码

    在百度搜索结果中,拿到你想要的elements,可以使用浏览器的查看元素,通过xpath方法获取

    运行此代码后截图效果如下:

    console输出:

    Starting ChromeDriver (v2.9.248315) on port 33834
    save snapshot path is:E:/open_baidu.png
    screen shot finished
    save snapshot path is:E:/input_keyWord.png
