通过Selenium的Java和Python客户端，有多种方法可以使用Selenium WebDriver进行截图。

Java方法

下面是不同的Java截图方法:

Using getScreenshotAs() from the TakesScreenshot interface: Code block: package screenShot; import java.io.File; import java.io.IOException; import org.apache.commons.io.FileUtils; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait; public class Firefox_takesScreenshot { public static void main(String[] args) throws IOException { System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); driver.get("https://login.bws.birst.com/login.html/"); new WebDriverWait(driver, 20).until(ExpectedConditions.titleContains("Birst")); File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File(".\\Screenshots\\Mads_Cruz_screenshot.png")); driver.quit(); } } Screenshot: If the webpage is jQuery enabled, you can use ashot from the pazone/ashot library: Code block: package screenShot; import java.io.File; import javax.imageio.ImageIO; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait; import ru.yandex.qatools.ashot.AShot; import ru.yandex.qatools.ashot.Screenshot; import ru.yandex.qatools.ashot.shooting.ShootingStrategies; public class ashot_CompletePage_Firefox { public static void main(String[] args) throws Exception { System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); driver.get("https://jquery.com/"); new WebDriverWait(driver, 20).until(ExpectedConditions.titleContains("jQuery")); Screenshot myScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(100)).takeScreenshot(driver); ImageIO.write(myScreenshot.getImage(),"PNG",new File("./Screenshots/firefoxScreenshot.png")); driver.quit(); } } Screenshot: Using selenium-shutterbug from assertthat/selenium-shutterbug library: Code block: package screenShot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import com.assertthat.selenium_shutterbug.core.Shutterbug; import com.assertthat.selenium_shutterbug.utils.web.ScrollStrategy; public class selenium_shutterbug_fullpage_firefox { public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); driver.get("https://www.google.co.in"); Shutterbug.shootPage(driver, ScrollStrategy.BOTH_DIRECTIONS).save("./Screenshots/"); driver.quit(); } } Screenshot:

Python方法

以下是Python中截图的不同方法:

Using save_screenshot() method: Code block: from selenium import webdriver driver = webdriver.Chrome(r'C:\Utility\BrowserDrivers\chromedriver.exe') driver.get("http://google.com") driver.save_screenshot('./Screenshots/save_screenshot_method.png') driver.quit() Screenshot: Using the get_screenshot_as_file() method: Code block: from selenium import webdriver driver = webdriver.Chrome(r'C:\Utility\BrowserDrivers\chromedriver.exe') driver.get("http://google.com") driver.get_screenshot_as_file('./Screenshots/get_screenshot_as_file_method.png') driver.quit() Screenshot: Using get_screenshot_as_png() method: Code block: from selenium import webdriver driver = webdriver.Chrome(r'C:\Utility\BrowserDrivers\chromedriver.exe') driver.get("http://google.com") screenPnG = driver.get_screenshot_as_png() # Crop it back to the window size (it may be taller) box = (0, 0, 1366, 728) im = Image.open(BytesIO(screenPnG)) region = im.crop(box) region.save('./Screenshots/get_screenshot_as_png_method.png', 'PNG', optimize=True, quality=95) driver.quit() Screenshot:

Java

public String captureScreen() {
    String path;
    try {
        WebDriver augmentedDriver = new Augmenter().augment(driver);
        File source = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);
        path = "./target/screenshots/" + source.getName();
        FileUtils.copyFile(source, new File(path)); 
    }
    catch(IOException e) {
        path = "Failed to capture screenshot: " + e.getMessage();
    }
    return path;
}

/**
 * Take a screenshot and move to the given folder location.
 *
 * @param driver
 * @param folderLocation
 * @return screenShotFilePath
 */
public static String captureScreenshot(WebDriver driver, String folderLocation) {

    // Variable to store screenshot's file path.
    String screenShotFilePath = null;

    // Generate unique id for screen shot name.
    String uniqueId = UUID.randomUUID().toString().substring(31);

    if (driver != null) {

        // Generate screenshot as a file
        File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

        // New screenshot file path with having file name
        screenShotFilePath = folderLocation + File.separator + uniqueId + ".png";

        // Move file to the destination location.
        FileUtils.moveFile(scrFile, new File(screenShotFilePath));
    }

    return screenShotFilePath;
}

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;
    }
}

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();
}

C# （Ranorex API）

public static void ClickButton()
{
    try
    {
        // code
    }
    catch (Exception e)
    {
        TestReport.Setup(ReportLevel.Debug, "myReport.rxlog", true);
        Report.Screenshot();
        throw (e);
    }
}
