In-Container Testing for OSGi, Java EE and CDI

OSGi Testing

  • Pax Exam lets you take control of the OSGi framework, the test framework (e.g. JUnit) and your system under test at the same time.
  • Pax Exam is also able to bootstrap a Apache Karaf container allowing you to directly execute commands, deploy features, etc.
  • Pax Exam has a test driver and a test container. The driver launches the OSGi framework and the system under test. It builds on-the-fly bundles from your test cases and injects them into the container. The driver is a plain old Java application and does not itself require an OSGi framework.
  • The test container comes in two flavours: The Native Container launches an embedded OSGi framework in the test driver VM. With the Forked Container, the system under test runs in a separate Java virtual machine under remote control from the test driver.
  • Test containers support different strategies for restarting or reusing the running OSGi framework for each test.
  • With the PaxExam JUnit runner, you simply need to add some special annotations and a configuration method to a JUnit class to run your OSGi tests. Thanks to this runner, any JUnit integration (e.g. in Eclipse or Maven Surefire) works with Pax Exam out of the box.
  • Pax Exam itself is distributed as Maven artifacts and lets you provision Maven bundles to your OSGi framework directly from local or remote Maven repositories.
  • Pax Exam supports all major OSGi frameworks (Equinox, Felix, Knopflerfish), based on OSGi 4.3 or higher.

Java EE 7 and CDI 1.1 Testing

  • Pax Exam 4.x generalizes the in-container testing approach to cover not only OSGi, but also Java EE and CDI components and applications.
  • Simply add @RunWith(PaxExam.class) to your JUnit test classes and let Pax Exam launch a full-blown Java EE server or a stand-alone CDI container and execute your tests within the container.
  • In Java EE mode, Pax Exam uses sensible defaults to build a test WAR on the fly, based on the classpath. There is no need to explicitly configure this WAR for each test.
  • All classes of a test suite can share the same setup.
  • Pax Exam 4.x supports GlassFish 4.x and Wildfly 8.x.
  • In CDI Java SE mode, Pax Exam supports Weld 2.x.
  • For other Java EE 6 or CDI 1.0 containers, have a look at Pax Exam 3.x.
