当前回答
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");
}
}

C# (Ranorex API)
public static void ClickButton()
{
try
{
// code
}
catch (Exception e)
{
TestReport.Setup(ReportLevel.Debug, "myReport.rxlog", true);
Report.Screenshot();
throw (e);
}
}
C#
public static void TakeScreenshot(IWebDriver driver, String filename)
{
// Take a screenshot and save it to filename
Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
screenshot.SaveAsFile(filename, ImageFormat.Png);
}
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);
是的,可以通过Selenium WebDriver来截屏。我目前使用Chrome驱动来抓取网站图片。请参考以下方法captureScreenshot()。
您还可以添加对web驱动程序的限制,例如
使用无头版的网页浏览器 当页面加载时禁用通知 启动全屏等。
如果一个网站配备了警报框,你的网页驱动程序将无法捕捉屏幕截图,因为异常将被抛出。在这种情况下,你需要关闭警告框,然后获取截图。下面的代码片段关闭警报框。
public void captureScreenshot() throws InterruptedException, IOException {
System.out.println("Creating Chrome Driver");
// Set Chrome Driver
System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
// Add arguments to Chrome Options
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("start-maximized");
chromeOptions.addArguments("--disable-gpu");
chromeOptions.addArguments("--start-fullscreen");
chromeOptions.addArguments("--disable-extensions");
chromeOptions.addArguments("--disable-popup-blocking");
chromeOptions.addArguments("--disable-notifications");
chromeOptions.addArguments("--window-size=1920,1080");
chromeOptions.addArguments("--no-sandbox");
chromeOptions.addArguments("--dns-prefetch-disable");
chromeOptions.addArguments("enable-automation");
chromeOptions.addArguments("disable-features=NetworkService");
WebDriver driver = new ChromeDriver(chromeOptions);
driver.get("https://www.google.com");
System.out.println("Wait a bit for the page to render");
TimeUnit.SECONDS.sleep(5);
System.out.println("Taking Screenshot");
File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
String imageDetails = "D:\\Images";
File screenShot = new File(imageDetails).getAbsoluteFile();
FileUtils.copyFile(outputFile, screenShot);
System.out.println("Screenshot saved: {}" + imageDetails);
}
}
为了接受警报框和获取截图:
String alertText = alert.getText();
System.out.println("ERROR: (ALERT BOX DETECTED) - ALERT MSG : " + alertText);
alert.accept();
File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
String imageDetails = "D://Images"
File screenShot = new File(imageDetails).getAbsoluteFile();
FileUtils.copyFile(outputFile, screenShot);
System.out.println("Screenshot saved: {}" + imageDetails);
driver.close();
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);
});
});
