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);
}
}

Java
String yourfilepath = "E:\\username\\Selenium_Workspace\\foldername";
// Take a snapshort
File snapshort_file = ((TakesScreenshot) mWebDriver)
.getScreenshotAs(OutputType.FILE);
// Copy the file into folder
FileUtils.copyFile(snapshort_file, new File(yourfilepath));
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);
}
Java
我想我应该给出完整的解决方案,因为有两种不同的方法获得截图。一个来自本地浏览器,另一个来自远程浏览器。我甚至将图像嵌入到HTML报告中:
@After()
public void selenium_after_step(Scenario scenario) throws IOException, JSONException {
if (scenario.isFailed()){
scenario.write("Current URL = " + driver.getCurrentUrl() + "\n");
try{
driver.manage().window().maximize(); // Maximize window to get full screen for chrome
}
catch (org.openqa.selenium.WebDriverException e){
System.out.println(e.getMessage());
}
try {
if(isAlertPresent()){
Alert alert = getAlertIfPresent();
alert.accept();
}
byte[] screenshot;
if(false /*Remote Driver flow*/) { // Get a screenshot from the remote driver
Augmenter augmenter = new Augmenter();
TakesScreenshot ts = (TakesScreenshot) augmenter.augment(driver);
screenshot = ts.getScreenshotAs(OutputType.BYTES);
}
else { // Get a screenshot from the local driver
// Local webdriver user flow
screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
}
scenario.embed(screenshot, "image/png"); // Embed the image in reports
}
catch (WebDriverException wde) {
System.err.println(wde.getMessage());
}
catch (ClassCastException cce) {
cce.printStackTrace();
}
}
//seleniumCleanup();
}
Python
每个WebDriver都有一个. save_截图(filename)方法。所以对于Firefox,它可以这样使用:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')
令人困惑的是,.get_screenshot_as_file(filename)方法也存在,它做同样的事情。
还有一些方法:.get_screenshot_as_base64()(用于嵌入HTML)和.get_screenshot_as_png()(用于检索二进制数据)。
注意,WebElements有一个.截图()方法,它的工作原理类似,但只捕获所选元素。

嗨,你可以在selenium中截图,这里是下面给出的代码,你可以在任何selenium项目中创建截图,我们也可以在aws中为失败的场景生成截图。
public boolean takeScreenshot(final String name) {
String screenshotDirectory = System.getenv("WORKING_DIRECTORY");
File screenshot =
((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
return screenshot.renameTo(new File(screenshotDirectory,
String.format("%s.png", name)));
}
