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();
}

是的，可以通过Selenium WebDriver来截屏。我目前使用Chrome驱动来抓取网站图片。请参考以下方法captureScreenshot()。

您还可以添加对web驱动程序的限制，例如

使用无头版的网页浏览器 当页面加载时禁用通知 启动全屏等。

如果一个网站配备了警报框，你的网页驱动程序将无法捕捉屏幕截图，因为异常将被抛出。在这种情况下，你需要关闭警告框，然后获取截图。下面的代码片段关闭警报框。

    public void captureScreenshot() throws InterruptedException, IOException {

        System.out.println("Creating Chrome Driver");

        // Set Chrome Driver
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");

        // Add arguments to Chrome Options
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--headless");
        chromeOptions.addArguments("start-maximized");
        chromeOptions.addArguments("--disable-gpu");
        chromeOptions.addArguments("--start-fullscreen");
        chromeOptions.addArguments("--disable-extensions");
        chromeOptions.addArguments("--disable-popup-blocking");
        chromeOptions.addArguments("--disable-notifications");
        chromeOptions.addArguments("--window-size=1920,1080");
        chromeOptions.addArguments("--no-sandbox");
        chromeOptions.addArguments("--dns-prefetch-disable");
        chromeOptions.addArguments("enable-automation");
        chromeOptions.addArguments("disable-features=NetworkService");

        WebDriver driver = new ChromeDriver(chromeOptions);
        driver.get("https://www.google.com");
        System.out.println("Wait a bit for the page to render");
        TimeUnit.SECONDS.sleep(5);
        System.out.println("Taking Screenshot");
        File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        String imageDetails = "D:\\Images";
        File screenShot = new File(imageDetails).getAbsoluteFile();
        FileUtils.copyFile(outputFile, screenShot);
        System.out.println("Screenshot saved: {}" + imageDetails);
    }
}

为了接受警报框和获取截图:

String alertText = alert.getText();
System.out.println("ERROR: (ALERT BOX DETECTED) - ALERT MSG : " + alertText);
alert.accept();
File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
String imageDetails = "D://Images"
File screenShot = new File(imageDetails).getAbsoluteFile();
FileUtils.copyFile(outputFile, screenShot);
System.out.println("Screenshot saved: {}" + imageDetails);
driver.close();

Python

您可以使用Python web驱动程序从windows中捕获图像。使用下面的代码哪个页面需要捕获屏幕截图。

driver.save_screenshot('c:\foldername\filename.extension(png, jpeg)')

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

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

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})
