是否可以使用Selenium WebDriver进行截图?

(注:不含硒遥控器)


当前回答

C#

你可以使用下面的代码片段/函数用Selenium截图:

    public void TakeScreenshot(IWebDriver driver, string path = @"output")
    {
        var cantakescreenshot = (driver as ITakesScreenshot) != null;
        if (!cantakescreenshot)
            return;
        var filename = string.Empty + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second + DateTime.Now.Millisecond;
        filename = path + @"\" + filename + ".png";
        var ss = ((ITakesScreenshot)driver).GetScreenshot();
        var screenshot = ss.AsBase64EncodedString;
        byte[] screenshotAsByteArray = ss.AsByteArray;
        if (!Directory.Exists(path))
            Directory.CreateDirectory(path);
        ss.SaveAsFile(filename, ImageFormat.Png);
    }

其他回答

JavaScript (Selenium-Webdriver)

driver.takeScreenshot().then(function(data){
   var base64Data = data.replace(/^data:image\/png;base64,/,"")
   fs.writeFile("out.png", base64Data, 'base64', function(err) {
        if(err) console.log(err);
   });
});

PHP (PHPUnit)

它使用PHPUnit_Selenium扩展版本1.2.7:

class MyTestClass extends PHPUnit_Extensions_Selenium2TestCase {
    ...
    public function screenshot($filepath) {
        $filedata = $this->currentScreenshot();
        file_put_contents($filepath, $filedata);
    }

    public function testSomething() {
        $this->screenshot('/path/to/screenshot.png');
    }
    ...
}

Java

我解决了这个问题。你可以扩展RemoteWebDriver,给它所有的接口,它的代理驱动程序实现:

WebDriver augmentedDriver = new Augmenter().augment(driver);
((TakesScreenshot)augmentedDriver).getScreenshotAs(...); // It works this way

Java

对于较新版本的Java, FileUtils函数不起作用。在这里,下面的功能可以完美地复制屏幕截图。

import java.io.File;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.io.FileHandler;

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
File destfile = new File(destination folder /filename.extension);
FileHandler.copy(scrfile, destfile);

Java

我无法得到可接受的答案,但根据当前的WebDriver文档,以下内容对我来说在OS X v10.9 (Mavericks)上的Java 7工作得很好:

import java.io.File;
import java.net.URL;

import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class Testing {

   public void myTest() throws Exception {
       WebDriver driver = new RemoteWebDriver(
               new URL("http://localhost:4444/wd/hub"),
               DesiredCapabilities.firefox());

       driver.get("http://www.google.com");

       // RemoteWebDriver does not implement the TakesScreenshot class
       // if the driver does have the Capabilities to take a screenshot
       // then Augmenter will add the TakesScreenshot methods to the instance
       WebDriver augmentedDriver = new Augmenter().augment(driver);
       File screenshot = ((TakesScreenshot)augmentedDriver).
               getScreenshotAs(OutputType.FILE);
   }
}
