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。

Set-Location PATH:\to\selenium
Add-Type -Path "Selenium.WebDriverBackedSelenium.dll"
Add-Type -Path "ThoughtWorks.Selenium.Core.dll"
Add-Type -Path "WebDriver.dll"
Add-Type -Path "WebDriver.Support.dll"
$driver = New-Object OpenQA.Selenium.PhantomJS.PhantomJSDriver
$driver.Navigate().GoToUrl("https://www.google.co.uk/")
# Take a screenshot and save it to filename
$filename = Join-Path (Get-Location).Path "01_GoogleLandingPage.png"
$screenshot = $driver.GetScreenshot()
$screenshot.SaveAsFile($filename, [System.Drawing.Imaging.ImageFormat]::Png)

$driver = New-Object OpenQA.Selenium.Chrome.ChromeDriver
$driver = New-Object OpenQA.Selenium.Firefox.FirefoxDriver
$driver = New-Object OpenQA.Selenium.IE.InternetExplorerDriver
$driver = New-Object OpenQA.Selenium.Opera.OperaDriver
Java
是的,这是可能的。下面以Java为例:
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));
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");
}
}
Ruby
time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M_%S')
file_path = File.expand_path(File.dirname(__FILE__) + 'screens_shot')+'/'+time +'.png'
#driver.save_screenshot(file_path)
page.driver.browser.save_screenshot file_path
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);
}
}
