Cannot set up Drone : NoClassDefFoundError: com/opera/core/systems/OperaDriver

Question

I'm following this tutorial: http://arquillian.org/guides/functional_testing_using_graphene/

But I got this error:

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.047 sec <<< FAILURE!
cn.ftc.test.BeanTest  Time elapsed: 1.045 sec  <<< ERROR!

Here is my arquillian.xml:

I was running this test in a remote JBoss-as-7.1.1 Server. I do not understand why the operadriver is needed...

Answer 1

The dependency org.jboss.arquillian.extension:arquillian-drone-webdriver-depchain:pom is not needed.

It should be enough to use dependencies listed in the tutorial.

You can upgrade version though, to:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.jboss.arquillian</groupId>
            <artifactId>arquillian-bom</artifactId>
            <version>1.1.3.Final</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>org.jboss.arquillian.extension</groupId>
            <artifactId>arquillian-drone-bom</artifactId>
            <version>1.2.3.Final</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>org.jboss.arquillian.selenium</groupId>
            <artifactId>selenium-bom</artifactId>
            <version>2.39.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

and

<dependency>
    <groupId>org.jboss.arquillian.graphene</groupId>
    <artifactId>graphene-webdriver</artifactId>
    <version>2.0.1.Final</version>
    <type>pom</type>
    <scope>test</scope>
</dependency>
