Ruby

time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M_%S')
file_path = File.expand_path(File.dirname(__FILE__) + 'screens_shot')+'/'+time +'.png'
#driver.save_screenshot(file_path)
page.driver.browser.save_screenshot file_path

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();
}

C# （Ranorex API）

public static void ClickButton()
{
    try
    {
        // code
    }
    catch (Exception e)
    {
        TestReport.Setup(ReportLevel.Debug, "myReport.rxlog", true);
        Report.Screenshot();
        throw (e);
    }
}

Ruby

time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M_%S')
file_path = File.expand_path(File.dirname(__FILE__) + 'screens_shot')+'/'+time +'.png'
#driver.save_screenshot(file_path)
page.driver.browser.save_screenshot file_path

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

你可以尝试一下shot API。它在GitHub上。

测试示例。
