Graphene RemoteWebDriver doesn't support augmentation properly -------------------------------------------------------------- Key: ARQGRA-256 URL: https://issues.jboss.org/browse/ARQGRA-256 Project: Arquillian Graphene Issue Type: Bug Components: core Affects Versions: 2.0.0.Alpha3 Environment: Graphene 2.0.0.Alpha3-SNAPSHOT Reporter: Ron Šmeral Assignee: Lukáš Fryč Priority: Critical When using a remote WebDriver, trying to take a screenshot as described in [WebDriver documentation|http://seleniumhq.org/docs/04_webdriver_advanced.jsp#taking...]: {code:java} @Drone WebDriver driver; ... WebDriver augmentedDriver = new Augmenter().augment(driver); byte[] screenshot = ((TakesScreenshot) augmentedDriver).getScreenshotAs(OutputType.BYTES); {code} results in the following exeception: {noformat} Caused by: java.lang.ClassFormatError: Duplicate method name&signature in class file org/openqa/selenium/remote/RemoteWebDriver$$EnhancerCGLIB$$58fd8af5$$EnhancerByCGLIB$$558c2b50 {noformat} If the augmentation is omitted, the {{TakesScreenshot}} interface can't be found: {noformat} java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebDriver$$EnhancerCGLIB$$eda133bb cannot be cast to org.openqa.selenium.TakesScreenshot {noformat} It seems that the CGLib-enhanced {{RemoteWebDriver}} instance contains the methods of capability providers ({{AddTakesScreenshot}}) but doesn't declare that it implements their corresponding interfaces ({{TakesScreenshot}}). Note that taking screenshots works without the augmentation when using a non-remote WebDriver. (When using augmentation it throws the _Duplicate method name&signature_ exception).
