title: How does Report Portal take screenshots of failed testcases in the case of TestNG framework?
body: <p>Does Report Portal use WebDriver to take the screenshot of failed testcases?
  I did not see the usage of WebDriver in the source code of the java-testNG listener agent.
  May i know how this is done?
  Or RP does not have the capability of capturing the screenshot for TestNG based frameworks?</p>
