Unable to take a screenshot in Selenium

Question

I try to capture a screenshot for each failure and wrote the following code, but this does not work.

public class TestFile { WebDriver driver = new FirefoxDriver(); @Test public void Testone(){ driver.get("http://www.google.com/"); } @AfterMethod(alwaysRun=true) public void catchExceptions(ITestResult result){ System.out.println("result"+result); String methodName = result.getName(); System.out.println(methodName); if(!result.isSuccess()){ try { File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile,new File("C:\\screenshot2.png" )); } catch (IOException e1) { e1.printStackTrace(); } } } } 

---

This does not work when

File driver scrFile = ((TakesScreenshot)). GetScreenshotAs (OutputType.FILE);

stack trace:

Answer 1

The stacktrace package you used is not a stack, but I think the testng log is.
The example you provided really works. I just skipped the test because in @AfterMethod the screenshot is only taken if the test fails: if (! Result.isSuccess ())
Then, when I ran the example again, I got:
java.io.FileNotFoundException: C: \ screenshot2.png (Access denied)
Then I changed the image location to D: where the permissions are correct, and it worked from end to end, I see a screenshot.

Hi sinisa229 mihajlovski,

Your script is working correctly. but there is a slight change in your script. If I do not comment on the line "assert false", it gives an error.

Try the following:

  WebDriver augmentedDriver = new Augmenter().augment(driver); File screenshot = ((TakesScreenshot)augmentedDriver). getScreenshotAs(OutputType.FILE); 

Instead

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
