Complaince Tests

The OSGi Alliance now provides access to Apache committers access to its TCK binariesCompliance Tests (CT). This page describes how to get access to the CTs and how to use run Felix subprojects against the TCK.

them with Felix subprojects.

Gaining Access to OSGi CTs

The general process is to send a request to the jcp-open@apache.org mailing requesting access. Since redistributing the OSGi CTs is not allowed, you will need to submit an NDA to be granted access to the SVN repo containing the binaries.

OSGi CT Overview

The CT The TCK is delivered as two JAR files, one for the core TCK CT and one for the compendium TCKCT. Each JAR file is comprised composed of several other JAR files, which are the actual compliance tests. Typically, there is one JAR per specification, except for the OSGi framework. The TCK CT uses BND as its testing harness, which in turn uses the OSGi R4.2 framework launching and embedding API to configure, launch, and install test bundles. Each test JAR file has an associated BND file which supplies the configuration BND needs to run the associated tests.

Modifying the BND files

Modifying the BND files is fairly straightforward, if not tedious. A typical BND file looks like this:

...

The following two examples show how to edit these files for the Felix framework and other Felix bundle subprojects.

Testing the Felix framework

The Felix framework is tested against the core CT. The first thing to do is extract the core TCKCT JAR file, which includes test suites for:

...

-runpath = \
    /path/to/felix/framework/org.apache.felix.framework-2.0.2.jar;version=file, \
    jar/com.springsource.junit-3.8.2.jar;version=file;export="junit.framework;version=3.8"

It Typically, it is not necessary to change anything else in the BND files and it is normal that the -runbundles setting is empty, since there are no additional bundles associated with testing the framework. The exception to this is for the framework test suites for security. To test with security enabled, you will need to add the framework security provider in -runbundles like this:

-runbundles = \
    /path/to/felix/framework.security/org.apache.felix.framework.security-1.0.0.jar.jar;version=file

After editing the BND files, run the tests using:

...

java -jar jar/bnd.jar runtests -title osgi.ct <bnd-file>

Where <bnd-file> specifies one or more BND files associated with the desired test suites.

Reports for the tests suites are generated in the reports/ subdirectory and are named after the appropriate test suiteSince the Felix framework does not fully implement the security-related portions of the OSGi specification, it is normal for it to fail the security-related test suites.

Testing a Felix bundle

The important parts are the following settings:

• -target specifies the bundles containing the tests.
• -runpath specifies the class path used to run the tests.
• -runbundles specifies the bundles to install for the tests.
• -runproperties specifies configuration properties to pass into the framework.

The following two examples show how to edit these files for the Felix framework and other subprojects.

Testing the Felix framework

The Felix framework is tested against the core TCK, which includes test suites for:

• Framework core (mandatory)
• Framework security (optional)
• Framework launching (mandatory)
• Framework launching security (optional)
• Package Admin (optional)
• Start Level (optional)
• URL Handlers (optional)
• Permission Admin (optional)
• Conditional Permission Admin (optional)

For each of the associated BND files, the -runpath needs to be edited to refer to the Felix framework; each one should look something like this after editing:

The core CT tests the framework implementation and its related services. The compendium CT tests the various non-framework-related specifications, which are implemented as bundles. For the most part, testing a bundle is similar to testing the framework.

Extract the compendium CT JAR file to access the individual test suites. Since most compendium service specification test suites require security, it is necessary to use a framework implementation that supports security. For the Felix framework, you will have to add the security provider to the -runbundles to enable security.

For example, to test Felix' Event Admin bundle, edit the -runbundles setting in org.osgi.test.cases.event.bnd to look something like this:

-runbundles

-runpath = \
    /path/to/felix/frameworkeventadmin/org.apache.felix.frameworkeventadmin-21.0.20.jar;version=file, \
    jar/com.springsource.junit-3.8.2/path/to/felix/framework.security/org.apache.felix.framework.security-1.0.0.jar.jar;version=file;export="junit.framework;version=3.8"

It is not necessary to change anything else in the BND and it is normal that the -runbundles setting is empty, since there are no additional bundles associated with testing the framework. After editing the BND files to refer to the appropriate bundles, run the tests using:

source runtests

...

Where <bnd-file> specifies one or more BND files for the associates test suites to run.

associated with the desired test suites. Reports for the tests suites are generated in the reports/ subdirectory and are named after the appropriate test suite.
