是否可以使用Selenium WebDriver进行截图?

Java

在附加TestName和Timestamp的情况下为Selenium中的失败捕获屏幕截图的方法。

public class Screenshot{
    final static String ESCAPE_PROPERTY = "org.uncommons.reportng.escape-output";
    public static String imgname = null;

    /*
     * Method to Capture Screenshot for the failures in Selenium with TestName and Timestamp appended.
     */
    public static void getSnapShot(WebDriver wb, String testcaseName) throws Exception {
      try {
      String imgpath = System.getProperty("user.dir").concat("\\Screenshot\\"+testcaseName);
      File f = new File(imgpath);
      if(!f.exists())   {
          f.mkdir();
        }
        Date d = new Date();
        SimpleDateFormat sd = new SimpleDateFormat("dd_MM_yy_HH_mm_ss_a");
        String timestamp = sd.format(d);
        imgname = imgpath + "\\" + timestamp + ".png";

        // Snapshot code
        TakesScreenshot snpobj = ((TakesScreenshot)wb);
        File srcfile = snpobj.getScreenshotAs(OutputType.FILE);
        File destFile = new File(imgname);
        FileUtils.copyFile(srcfile, destFile);

      }
      catch(Exception e) {
          e.getMessage();
      }
   }

使用RemoteWebDriver,在增加了节点的截图功能后,我将像这样存储截图:

void takeScreenShotMethod(){
    try{
        Thread.sleep(10000);
        long id = Thread.currentThread().getId();
        BufferedImage image = new Robot().createScreenCapture(new Rectangle(
            Toolkit.getDefaultToolkit().getScreenSize()));
        ImageIO.write(image, "jpg", new File("./target/surefire-reports/"
            + id + "/screenshot.jpg"));
    }
    catch( Exception e ) {
        e.printStackTrace();
    }
}

你可以在任何需要的地方使用这种方法。然后,我假设您可以在surefire-reports/html/custom.css中定制maven-surefire-report-plugin的样式表,以便您的报告包含到每个测试的正确截图的链接。

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"));

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:

import java.io.File;
import java.io.IOException;

import org.apache.maven.surefire.shade.org.apache.maven.shared.utils.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
/**

public class ScreenShotMaker {

    // take screen shot on the test failures
    public void takeScreenShot(WebDriver driver, String fileName) {
        File screenShot = ((TakesScreenshot) driver)
                .getScreenshotAs(OutputType.FILE);
        try {
            FileUtils.copyFile(screenShot, new File("src/main/webapp/screen-captures/" + fileName + ".png"));

        } catch (IOException ioe) {
            throw new RuntimeException(ioe.getMessage(), ioe);
        }
    }

}

Ruby(黄瓜)

After do |scenario| 
    if(scenario.failed?)
        puts "after step is executed"
    end
    time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M')

    file_path = File.expand_path(File.dirname(__FILE__) + '/../../../../../mlife_screens_shot')+'/'+time +'.png'

    page.driver.browser.save_screenshot file_path
end

Given /^snapshot$/ do
    time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M')

    file_path = File.expand_path(File.dirname(__FILE__) + '/../../../../../mlife_screens_shot')+'/'+time +'.png'
    page.driver.browser.save_screenshot file_path
end
