如何使用selenium中的Ashot为整个网页拍摄屏幕快照

Question

我无法在selenium web驱动程序中使用testng和maven获得结果，它显示在控制台中

java.lang.VerifyError：(班级:军政府/新考试，方法: java.lang.Class.privateGetDeclaredMethods(Unknown签名：()V)不兼容的参数，作用在java.lang.Class.getDeclaredMethods0(原生方法)在java.lang.Class.privateGetPublicMethods(Unknown源)在java.lang.Class.getMethods(未知源)在org.testng.internal.TestNGClassFinder.(TestNGClassFinder.java:63) at org.testng.TestRunner.initMethods(TestRunner.java:424) at org.testng.TestRunner.init( org.testng.TestRunner.init(TestRunner.java:217) at org.testng.TestRunner.(TestRunner.java:169)在org.testng.remote.support.RemoteTestNG6_9_10$1.newTestRunner(RemoteTestNG6_9_10.java:28) at org.testng.remote.support.RemoteTestNG6_9_10$DelegatingTestRunnerFactory.newTestRunner(RemoteTestNG6_9_10.java:61) at org.testng.SuiteRunner$ProxyTestRunnerFactory.newTestRunner(SuiteRunner.java:594) )org.testng.SuiteRunner.init(SuiteRunner.java:168) at org.testng.SuiteRunner.(SuiteRunner.java:117) at org.testng.TestNG.createSuiteRunner(TestNG.java:1300) at org.testng.TestNG.createSuiteRunners(TestNG.java:1287) at org.testng.TestNG.runSuitesLocally(TestNG.java:1141) at org.testng.TestNG.runSuites(TestNG.java:1075) at org.testng.TestNG.run(TestNG.java:1047)在org.testng.remote.AbstractRemoteTestNG.run(AbstractRemoteTestNG.java:126) at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:137) at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:58)

我的脚本是

WebElement bookTitleElement =    driver.findElement(By.xpath("//h1[@id='item_bib_title']"));
String bookTitleValue = bookTitleElement.getText();

assertEquals(bookTitleElement.isDisplayed(), true);
assertTrue(bookTitleValue.length()> 0);

}

}

Answer 1

试试这个。

 public class Screenshot {

public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub

    FirefoxDriver driver = new FirefoxDriver();
    driver.get("http://yahoo.com");
    driver.manage().window().maximize();

    File scrFile = (driver.getScreenshotAs(OutputType.FILE));  
    FileUtils.copyFile(scrFile, new File("d:\\Selenium\\screenshot2.png"));
    }
}

如果您有任何疑问，请告诉我。:-)

这就是我一直使用aShot的方式。这很好，因为它捕获了整个页面的图像，而不仅仅是当前窗格的视图。

private void writeToFile(Path path) {
    try {
        path.toFile().mkdirs();

        Files.deleteIfExists(path);
        Files.createFile(path);

        LOGGER.debug("Writing screenshot to: {}", path);

        writeSsWithAShot(path);

    } catch (IOException e) {
        throw new RuntimeException(
            "Unable to capture and write screenshot to " + path.toString(),
            e
        );
    }
}

private void writeSsWithAShot(Path path) throws IOException {

    ru.yandex.qatools.ashot.Screenshot aShot = new AShot()
        .shootingStrategy(ShootingStrategies.viewportPasting(1500))
        .takeScreenshot(driver);

    BufferedImage image = aShot.getImage();
    ImageIO.write(image, "png", path.toFile());
}
