[arquillian-issues] [JBoss JIRA] (ARQ-1050) Drone fails to instantiate drivers when operadriver isn't on classpath

[Bartosz Majsak (JIRA)]

    [ https://issues.jboss.org/browse/ARQ-1050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12923036#comment-12923036 ] 

Bartosz Majsak commented on ARQ-1050:
-------------------------------------

I believe this problem should be rethink. I will give you an example from yesterday's Hackergarten at Devoxx.

We were working on Drone-powered tests of [AngularJS application|https://github.com/vorburger/mifosx-ui-selenium-webdriver-tests/pull/2] and we wanted to run it using jetty embedded. And here's the classpath hell:
* phantomjs has it's own jetty 
* htmlunit another one

But if I remove any of them I simply can use Drone at all. Is it really necessary to follow all-or-nothing strategy?
