最近我写了一个在 Karaf 容器中运行的集成测试，它使用 Pax Exam，这是我的代码：

                            .build())

    return combined;
}

@Test

    Assert.assertNotNull(this.blueprintContainer);

    Assert.assertNotNull(this.blueprintContainer.getComponentInstance("mofFrameworkServiceImpl"));
    // Assert.assertNotNull(module);

}

protected Set<Feature> getFeatures(String features) throws Exception {
    String[] featureArray = features.split("\\s");
    Set<Feature> featureSet = new HashSet<Feature>();
    for (String s : featureArray) {

        if (s == null || (s = s.trim()).isEmpty()) {
            continue;
        }
        Feature feature = this.featuresService.getFeature(s);
        if (feature == null) {
            throw new IllegalArgumentException("The feature which named:"
                    + s + " can not be found.");
        }
        featureSet.add(feature);
    }
    return featureSet;
}

}

但我发现它无法通过测试，因为测试包找不到我的自定义服务类（IFramework 框架）并报告：

java.lang.ClassNotFoundException:     com.mercury.mof.foundation.framework.api.modular.IFramework not found by PAXEXAM-PROBE-45604164-c35f-448b-9627-af8adb7e16f7 [110]

我不知道问题出在哪里，实际上我在我的基础测试中注入了一些标准的 osgi 服务，它就像一个魅力，为什么在我使用自己的服务时会导致麻烦？有人可以给我一些提示吗？非常感谢

确保您的测试可以看到 IFramework 类的最佳方法是确保提供该类的包已安装在您的容器中。在 @Configuration 注解的方法中使用 mavenBundle 是一个不错的方法。

您需要注意的事项： i) 包含 IFramework 的包导出类。ii) 如果您使用 maven 协调，请确保已安装人工制品（请参阅 [1]）。iii) 确保满足捆绑导出 IFramework 的依赖关系。

所以与您的代码相关的评论：i）您不需要安装 osgi 核心、纲要和企业（它们由 karaf 提供）。ii) 无需使用提供的东西来添加类和资源（我看到作为捆绑包安装的类和测试资源无论如何都将可用）。

[1]：如果您的集成测试是与您在测试中使用的类相同的 maven 模块的一部分，您需要注意测试是在工件安装到您的存储库之前运行的，因此使用 maven 坐标可以导致到问题。如果是这种情况，请考虑拆分测试，或者不要使用 maven 坐标。
