+
+The [OSGi Testing Support](https://github.com/eclipse-osgi-technology/osgi-test#osgi-testing-support) is a great library for testing OSGi applications,
+and PDE now add first-class support as it does for OSGi Annotations already.
+
+To enable this do the following:
+
+1. Make sure your target platform contains the necessary OSGi test dependencies, to make this more easy PDE provides a feature named `org.eclipse.pde.osgitest.dependencies.feature`.
+2. Go to the [Build Path Settings](https://help.eclipse.org/latest/topic/org.eclipse.jdt.doc.user/reference/ref-properties-build-path.htm) and add the JUNIT Library under the [Libraries Tab](https://help.eclipse.org/latest/topic/org.eclipse.jdt.doc.user/reference/ref-properties-build-path.htm#libraries) but do not add any JUnit or OSGi Testing imports/requirements to your manifest!
+3. Place your Tests into a source folder marked as test source
+
+PDE will then automatically add required dependencies for OSGi Testing Support and you can use all the standard annotations right now.
+
+After that just run your tests as the usual plugin test, you can find an example [here](examples/osgitest-example.zip), if you find any issues or has suggestions don't hesitate to let us know and open an issue [here](https://github.com/eclipse-pde/eclipse.pde/issues).
