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);
}
}

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();
}

我使用下面的c#代码来获取整个页面或仅一个浏览器截图
public void screenShot(string tcName)
{
try
{
string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
ITakesScreenshot screen = driverScript.driver as ITakesScreenshot;
Screenshot screenshot = screen.GetScreenshot();
screenshot.SaveAsFile(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
if (driverScript.last == 1)
this.writeResult("Sheet1", "Fail see Exception", "Status", driverScript.resultRowID);
}
catch (Exception ex)
{
driverScript.writeLog.writeLogToFile(ex.ToString(), "inside screenShot");
}
}
public void fullPageScreenShot(string tcName)
{
try
{
string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
Rectangle bounds = Screen.GetBounds(Point.Empty);
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using (Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
}
bitmap.Save(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
}
if (driverScript.last == 1)
this.writeResult("Sheet1", "Pass", "Status", driverScript.resultRowID);
}
catch (Exception ex)
{
driverScript.writeLog.writeLogToFile(ex.ToString(), "inside fullPageScreenShot");
}
}
PHP
public function takescreenshot($event)
{
$errorFolder = dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . "ErrorScreenshot";
if(!file_exists($errorFolder)){
mkdir($errorFolder);
}
if (4 === $event->getResult()) {
$driver = $this->getSession()->getDriver();
$screenshot = $driver->getWebDriverSession()->screenshot();
file_put_contents($errorFolder . DIRECTORY_SEPARATOR . 'Error_' . time() . '.png', base64_decode($screenshot));
}
}
C#
public void TakeScreenshot()
{
try
{
Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
ss.SaveAsFile(@"D:\Screenshots\SeleniumTestingScreenshot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
throw;
}
