如何在Selenium webdriver和Java API中录制视频

Question

我有每天晚上运行的自动化脚本(大约50个脚本或测试用例)。我想录制每个测试用例的视频(Selenium Java API + Cucumber)。有没有什么工具或方法可以用来分别控制每个测试用例的视频录制？我希望在测试用例设置期间开始录制，在拆卸期间停止录制，并使用指定的名称和日期将视频保存到本地。因此，我应该为每个测试用例提供50个视频(更好的做法是只为失败的测试用例保存视频)

有没有办法将此功能集成到我用于设置和拆卸的代码中？

我找到了一个解决方案here，但如果你找到更好的解决方案，你可以发布另一个回复：

org.monte.screenrecorder.ScreenRecorder  screenRecorder = new ScreenRecorder...

完整主代码：

import static org.monte.media.FormatKeys.EncodingKey;
import static org.monte.media.FormatKeys.FrameRateKey;
import static org.monte.media.FormatKeys.KeyFrameIntervalKey;
import static org.monte.media.FormatKeys.MIME_AVI;
import static org.monte.media.FormatKeys.MediaTypeKey;
import static org.monte.media.FormatKeys.MimeTypeKey;
import static org.monte.media.VideoFormatKeys.CompressorNameKey;
import static org.monte.media.VideoFormatKeys.DepthKey;
import static org.monte.media.VideoFormatKeys.ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE;
import static org.monte.media.VideoFormatKeys.QualityKey;

import java.awt.Dimension;
import java.awt.GraphicsConfiguration;
import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;
import java.awt.Toolkit;
import java.io.File;

import org.monte.media.Format;
import org.monte.media.FormatKeys.MediaType;
import org.monte.media.math.Rational;
import org.monte.screenrecorder.ScreenRecorder;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public class VideoReord {

    public static final String USER_DIR = "user.dir";
    public static final String DOWNLOADED_FILES_FOLDER = "downloadFiles";

    private ScreenRecorder screenRecorder;

    public static void main(String[] args) throws Exception {

        VideoReord videoReord = new VideoReord();
        videoReord.startRecording();

        DesiredCapabilities capabilities = DesiredCapabilities.chrome();
        WebDriver driver = new ChromeDriver(capabilities);
        driver.get("http://www.google.com");

        WebElement element = driver.findElement(By.name("q"));
        element.sendKeys("BreizhCamp 2018");
        element.submit();
        System.out.println("Page title is: " + driver.getTitle());
        driver.quit();
        videoReord.stopRecording();
    }

    public void startRecording() throws Exception {
        File file = new File(System.getProperty(USER_DIR) + File.separator + DOWNLOADED_FILES_FOLDER);

        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        int width = screenSize.width;
        int height = screenSize.height;

        Rectangle captureSize = new Rectangle(0, 0, width, height);

        GraphicsConfiguration gc = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration();

        this.screenRecorder = new SpecializedScreenRecorder(gc, captureSize, new Format(MediaTypeKey, MediaType.FILE, MimeTypeKey, MIME_AVI),
                new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE, CompressorNameKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE, DepthKey, 24, FrameRateKey,
                        Rational.valueOf(15), QualityKey, 1.0f, KeyFrameIntervalKey, 15 * 60),
                new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, "black", FrameRateKey, Rational.valueOf(30)), null, file, "MyVideo");
        this.screenRecorder.start();

    }

    public void stopRecording() throws Exception {
        this.screenRecorder.stop();
    }
}

SpecializedScreenRecorder类扩展了ScreenRecorder类：

import java.awt.AWTException;
import java.awt.GraphicsConfiguration;
import java.awt.Rectangle;
import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.monte.media.Format;
import org.monte.media.Registry;
import org.monte.screenrecorder.ScreenRecorder;

public class SpecializedScreenRecorder extends ScreenRecorder {

    private String name;

    public SpecializedScreenRecorder(GraphicsConfiguration cfg, Rectangle captureArea, Format fileFormat, Format screenFormat, Format mouseFormat, Format audioFormat, File movieFolder, String name)
            throws IOException, AWTException {
        super(cfg, captureArea, fileFormat, screenFormat, mouseFormat, audioFormat, movieFolder);
        this.name = name;
    }

    @Override
    protected File createMovieFile(Format fileFormat) throws IOException {
        if (!movieFolder.exists()) {
            movieFolder.mkdirs();
        } else if (!movieFolder.isDirectory()) {
            throw new IOException("\"" + movieFolder + "\" is not a directory.");
        }

        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH.mm.ss");

        return new File(movieFolder, name + "-" + dateFormat.format(new Date()) + "." + Registry.getInstance().getExtension(fileFormat));
    }
}

Maven导入：

警告:如果在没有图形用户界面的unix上使用此命令，则会出现以下错误：

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

我看了Jenkins和Travis-ci的Xvfb插件，我重新编辑了这篇文章。

EDIT 1:

如果你在没有图形用户界面的unix上使用它，你可以使用Jenkins + Xvfb插件。

Answer 2

你可以看看谢尔盖·皮罗戈夫的“this library”。

Answer 3

您可以尝试使用Selenium-Grid-Extras或Zalenium。

两者都构建在webdriver之上，并自动进行记录。
