JavaScript (Selenium-Webdriver)

driver.takeScreenshot().then(function(data){
   var base64Data = data.replace(/^data:image\/png;base64,/,"")
   fs.writeFile("out.png", base64Data, 'base64', function(err) {
        if(err) console.log(err);
   });
});

你可以尝试一下shot API。它在GitHub上。

测试示例。

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();
}

Ruby

require 'rubygems'
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :ie
driver.get "https://www.google.com"
driver.save_screenshot("./screen.png")

更多的文件类型和选项可用，您可以在文件takes_screenshot.rb中看到它们。

JavaScript (Selenium-Webdriver)

driver.takeScreenshot().then(function(data){
   var base64Data = data.replace(/^data:image\/png;base64,/,"")
   fs.writeFile("out.png", base64Data, 'base64', function(err) {
        if(err) console.log(err);
   });
});

Python

def test_url(self):
    self.driver.get("https://www.google.com/")
    self.driver.save_screenshot("test.jpg")

它将在脚本保存的同一目录下保存一个截图。
