Putting custom annotation on Drone creates multiple instances ------------------------------------------------------------- Key: ARQ-1771 URL: https://issues.jboss.org/browse/ARQ-1771 Project: Arquillian Issue Type: Bug Security Level: Public(Everyone can see) Components: Extension - Drone Affects Versions: drone_2.0.0.Alpha1 Reporter: Stefan Miklosovic I have a test case like this {code} @RunWith(Arquillian.class) @RunAsClient public class SomeTestCase { @Drone @Mobile @Custom private WebDriver mobile; // tests } {code} where @Custom is just an annotation: {code} @Retention(RetentionPolicy.RUNTIME) @Target({ ElementType.FIELD, ElementType.PARAMETER }) public @interface Custom { } {code} it is _not_ annotated with @Qualifier. Realize that the same problem arise when using @OperateOnDeployment from Arquillian which is not annotated with @Qualifier neither. I am getting this: http://pastebin.com/raw.php?i=i9DVqeaC You see that InstrumentationPerformDecider.decidePerformingInstrumentation observes BeforeDroneInstantiated so when it is treated twice, you are going to instantiate two Drones which is another argument why Drone does it wrong. When I declare Drone injection like that, it results into two instances of WebDrivers so that means it instruments Android package twice with two Selendroids so that mean I am getting NoUniqueWebDriverException when I want to start some activity because from now on you have "by accident" two webdrivers instrumenting the same deployment as a result of a bug where putting custom annotation on Drone instantiates it twice.
