使用Pax-Exam进行OSGi测试失败，未找到容器错误

Question

使用Pax-Exam进行OSGi测试失败，并显示“找不到容器错误”。

这是因为我从java7升级到了java8，因此我不得不将pax-exam-2.3.0.jar (与java8不兼容)改为pax-exam-4.4.0.jar。以及它们的其他依赖项。在早先的config中，我们曾经编写过felix()，但现在已经改变了。

现在如何启动felix容器？

配置：

@RunWith(PaxExam.class)
@ExamReactorStrategy(PerMethod.class)
public class GibsonMiniAGLTest
{
    @Configuration
    public Option[] config() {



        return options(


                vmOption("-Dcom.sun.management.jmxremote"),
                systemPackages("sun.misc",
                        "sun.security.util",
                        "sun.security.x509",
                        "com.sun.media.imageioimpl.plugins.jpeg2000"
                        ),
                bootDelegationPackages(
                    "sun.misc.*",
                    "com.sun.*"
                ),
                bundle("abc.jar"),
                junitBundles()

            );
    }
 }

Ant文件：

<target name="run_STOSGI">
        <property file="build/jamunTimeOut.properties"/>
        <echo message="Calculated TimeOut for Jamun_Tests in MilliSeconds = ..........." />
        <echo message="${timeout}" />
        <junit printsummary="yes" showoutput="yes" timeout="${timeout}" haltonfailure="on" maxmemory="256M" fork="on">
            <jvmarg value="-Dorg.xml.sax.driver=${saxParser}" />
            <classpath>
                <pathelement path="${jamun.path}" />
                <pathelement path="${junit.path}" />
                <pathelement path="${jar}/core.jar" />
            </classpath>
            <formatter type="xml" />
            <sysproperty key="BAT_PLUGIN" value="${BAT_PLUGIN}"/>
            <test name="com.adobe.gibsontests.SmokeTestOSGIosgi" />
        </junit>
        <move todir="${smokeTest_Location}" failonerror="false" overwrite="true" >
            <fileset dir="${smoketest_temp}"/>
        </move>
    </target>

堆栈跟踪：

  <testcase classname="com.adobe.gibsontests.SmokeTestOSGIosgi" name="initializationError" time="0.004">
    <error message="No TestContainer implementation in Classpath" type="org.ops4j.pax.exam.TestContainerException">org.ops4j.pax.exam.TestContainerException: No TestContainer implementation in Classpath

有人能指出我遗漏了什么吗？

我尝试在独立环境中运行pax-exam，但也失败了，错误为: org.ops4j.pax.exam.TestContainerException: No service org.osgi.framework.launch.FrameworkFactory in META-INF/org.osgi.framework.launch.FrameworkFactory on classpath

Answer 1

正如错误消息所述：“类路径中没有TestContainer实现”。您需要将容器实现放到类路径上。

有几种选择。最基本的是：

1.：

<dependency>
  <groupId>org.ops4j.pax.exam</groupId>
  <artifactId>pax-exam-container-native</artifactId>
  <scope>test</scope>
</dependency>

2.：

<dependency>
  <groupId>org.ops4j.pax.exam</groupId>
  <artifactId>pax-exam-container-forked</artifactId>
  <scope>test</scope>
</dependency>

也有一些更复杂的，如karaf容器等。
