Java (Robot Framework)
我使用这种方法进行截图。
void takeScreenShotMethod(){
try{
Thread.sleep(10000)
BufferedImage image = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
ImageIO.write(image, "jpg", new File("./target/surefire-reports/screenshot.jpg"));
}
catch(Exception e){
e.printStackTrace();
}
}
你可以在任何需要的地方使用这种方法。
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)
你可以使用Webdriverclass对象创建一个webdriver支持的selenium对象,然后你可以截屏。
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
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();
}
