Question

我目前正在尝试使用PAX-EXAM + KARAF编写OSGI集成测试，并遇到一个问题，即pax考试尝试在依赖包实际启动/初始化为容器之前执行测试方法。奇怪的是，有时测试会成功，在这种情况下，所有捆绑/上下文都会被启动和记录，但大多数情况下都没有。方法的延迟无济于事:(任何人都可以帮助解决这个问题吗？

我正在使用 PAX-EXAM 2.6.0， org.apache.karaf.tooling.exam.container 2.3.0， apache-karaf 2.3.0。

代码：

@Inject
BundleContext bundleContext;

@Inject
    EntityManagerFactoryService entityManagerFactoryService;//Service exposed trough OSGI

    protected EntityManager entityManager;

    @Before
    public void init() throws InterruptedException {
        entityManager = entityManagerFactoryService.getEntityManagerFactory().createEntityManager();
    }

@Configuration
    public static Option[] configuration() throws Exception {

    return new Option[] {
            karafDistributionConfiguration().frameworkUrl(maven().groupId("org.apache.karaf").artifactId("apache-karaf").type("zip").versionAsInProject())
                    .karafVersion("2.3.0").name("Apache Karaf"),                
mavenBundle("com.google.guava", "guava", "13.0.1").startLevel(30),
mavenBundle("com.mysql.jdbc", "com.springsource.com.mysql.jdbc", "5.1.6").startLevel(30),
                mavenBundle("javax.persistence", "com.springsource.javax.persistence", "2.0.0").startLevel(30),
                mavenBundle("org.apache.commons", "com.springsource.org.apache.commons.lang", "2.6.0").startLevel(30),

...the rest of bundles  

junitBundles(), };

测试方法：

@Test
    public void contextNotNull() {
        Assert.assertNotNull(entityManagerFactoryService);
    }

日志：

也试过没有运气：

protected <T> Object getService(Class<T> serviceClass) {
    int maxCount = 5;
    int delay = 5000;
    for (int i = 0; i <= maxCount; i++) {
        if (bundleContext.getServiceReference(serviceClass) != null) {
            ServiceReference<T> serviceReference = bundleContext.getServiceReference(serviceClass);
            return bundleContext.getService(serviceReference);
        } else {
            try {
                Thread.sleep(delay);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
    return null;
}

@Before
public void init() throws InterruptedException {
    EntityManagerFactoryService emfs = (EntityManagerFactoryService) getService(EntityManagerFactoryService.class);
    entityManager = entityManagerFactoryService.getEntityManagerFactory().createEntityManager();
}

Answer 1

您确定您的EntityManager正在运行并可用作服务吗？您很可能缺少某些依赖项，这就是为什么包含该服务的捆绑包未完全启动的原因。

Answer 2

目前的pax考试3.3.0现在完全支持karaf作为容器。以前的karaf考试代码现已全部转到pax考试。

OSGI集成测试，Pax Exam探针在容器包开始之前执行测试
