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;
}

Java
String yourfilepath = "E:\\username\\Selenium_Workspace\\foldername";
// Take a snapshort
File snapshort_file = ((TakesScreenshot) mWebDriver)
.getScreenshotAs(OutputType.FILE);
// Copy the file into folder
FileUtils.copyFile(snapshort_file, new File(yourfilepath));
更新2022
要在Selenium中截取屏幕截图,我们使用一个名为TakesScreenshot的接口,它使Selenium WebDriver能够捕捉屏幕截图并以不同的方式存储它。它有一个getScreenshotAs()方法,用于捕获屏幕截图并将其存储在指定的位置。
//Convert webdriver to TakeScreenshot
File screenshotFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
在上面的代码中,它将WebDriver对象(驱动程序)转换为TakeScreenshot。并调用getScreenshotAs()方法通过提供参数*OutputType.FILE来创建图像文件。
我们可以使用File对象将图像复制到我们想要的位置,如下所示,使用FileUtils类。
FileUtils.copyFile(screenshotFile , new File("C:\\temp\\screenshot.png));
捕获整个页面
Selenium WebDriver没有提供捕获整个页面截图的固有功能。为了捕获整个页面的截图,我们必须使用一个名为shot的第三方库。它提供了截取特定WebElement的截图以及整页截图的功能。
捕获屏幕大小的图像
Screenshot screenshot = new Ashot().takeScreenshot(driver);
捕获整个页面的截图
Screenshot s=new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
ImageIO.write(s.getImage(),"PNG",new File("<< file path>>"));
在上面的代码中,1000是以毫秒为单位的滚动时间。换句话说,这意味着该程序将滚动每1000毫秒来截取屏幕截图。
捕获一个元素
在Selenium中有两种方法来捕获web元素的屏幕截图。
取全屏图像,然后根据网页元素的尺寸裁剪图像。 在web元素上使用getScreenshotAs()方法。(这只在selenium版本4.X中可用)
Java
我解决了这个问题。你可以扩展RemoteWebDriver,给它所有的接口,它的代理驱动程序实现:
WebDriver augmentedDriver = new Augmenter().augment(driver);
((TakesScreenshot)augmentedDriver).getScreenshotAs(...); // It works this way
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);
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:
