我想在Karaf 4.2.x中测试Camel 2.24.x路由。我使用Pax-Exam 4.13.1运行Karaf。 Camel Testing Manual不包括Karaf测试。对于较旧的Karaf和Camel版本，有博客文章展示了如何通过扩展CamelTestSupport中的测试类来做到这一点：
- Testing Camel JPA routes with Pax-Exam and Karaf
- Testing (utest and itest) Apache Camel Blueprint route
但是，它们太旧了，以至于代码不经过调整就无法运行。前者是非常绝望的，我已停止尝试对其进行修复。对于后者，我能够使其在Karaf 2.4 with Camel 2.12.1 on JDK 8上运行，但不能在当前的Karaf 4.2.7 using Camel 2.24.2上运行。
使用当前的Karaf 4和Camel 2.24，当CamelTestSupport试图在JndiContext中创建CamelTestSupport#createRegistry时，出现以下错误消息。

缺少的类位于camel-core中，它曾经与较早版本的Camel和Karaf一起使用，因此我很茫然，为什么在使用最新的Karaf和Camel时该类不可用。 / p>
找不到CamelInitialContextFactory的原因可能是什么？与旧版本一样，我在测试中install camel-blueprint and camel-test，所以我希望应该包含camel-core。
在Karaf上使用CamelTestSupport还是个好主意吗？尽管有一个CamelKarafTestSupport似乎证明了这种方法，但我找不到这种测试的可行示例，也无法自己使用。使用CamelKarafTestSupport时，我收到一条错误消息，告诉我ProbeInvoker从未出现过：

我应该走一条不同的路线，也许是camel-itest-karaf广泛使用的AbstractFeatureTest中的camel-test-karaf吗？
