硒化/ Java

以下是Selenide项目是如何做到这一点的，这比任何其他方式都要简单:

import static com.codeborne.selenide.Selenide.screenshot;    
screenshot("my_file_name");

JUnit:

@Rule
public ScreenShooter makeScreenshotOnFailure = 
     ScreenShooter.failedTests().succeededTests();

美国小妞TestNG:

import com.codeborne.selenide.testng.ScreenShooter;
@Listeners({ ScreenShooter.class})

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

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:

public static void getSnapShot(WebDriver driver, String event) {

    try {
        File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        BufferedImage originalImage = ImageIO.read(scrFile);
        //int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();
        BufferedImage resizedImage = CommonUtilities.resizeImage(originalImage, IMG_HEIGHT, IMG_WIDTH);
        ImageIO.write(resizedImage, "jpg", new File(path + "/"+ testCaseId + "/img/" + index + ".jpg"));
        Image jpeg = Image.getInstance(path + "/" + testCaseId + "/img/"+ index + ".jpg");
        jpeg.setAlignment(Image.MIDDLE);
        PdfPTable table = new PdfPTable(1);
        PdfPCell cell1 = new PdfPCell(new Paragraph("\n"+event+"\n"));
        PdfPCell cell2 = new PdfPCell(jpeg, false);
        table.addCell(cell1);
        table.addCell(cell2);
        document.add(table);
        document.add(new Phrase("\n\n"));
        //document.add(new Phrase("\n\n" + event + "\n\n"));
        //document.add(jpeg);
        fileWriter.write("<pre>        " + event + "</pre><br>");

        e.printStackTrace();
    }
