Когда я использую Ashot с селеном для захвата снимка экрана для определенного веб-элемента, он не работает. У меня также прикрепил логи для ознакомления.
Скриншот для полной страницы работает.
Примечание. Я обновил последнюю банку, как указано в комментарии.
Я использую драйвер Chrome, отдельную банку selenium 3.8.1, банку Ashot 1.5.2.
@Test
public void launchBrowser()
{
System.setProperty("webdriver.chrome.driver","/Applications/webdriver/chromedriver");
driver = new ChromeDriver();
}
@Test
public void openApplication() throws IOException, InterruptedException
{
driver.get("https://myurl");
driver.manage().window().maximize();
WebDriverWait wait = new WebDriverWait(driver, 50);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("commonuileftpanel")));
WebElement portal =driver.findElement(By.id("commonuileftpanel"));
Screenshot myScreenshot = new AShot().takeScreenshot(driver,portal);
BufferedImage original = myScreenshot.getImage();
BufferedImage expected = ImageIO.read(new File("/Applications/webdriver/results.png"));
ImageDiff diff = new ImageDiffer().makeDiff(original, expected);
BufferedImage difffullImage = diff.getMarkedImage();
File outputfile = new File("/Applications/webdriver/diffImage.png");
ImageIO.write(difffullImage, "PNG", outputfile);
Boolean diffval = diff.hasDiff();
Assert.assertFalse(diffval);
driver.quit();
}
@Test
public void closeDriver()
{
if(driver!=null)
{
driver.close();
}
Добавлен снимок экрана:
