Tycho uses the transitive dependencies of the test bundle to populate the list of bundles for the test runtime.
If you require anything at test runtime not explicitly required by those bundles, you need to give Tycho a hint.

Typically fragments are not directly required but only end up in the installation included via features being installed, so in this case e.g. adding a dependency on a feature that brings the fragment works around the problem.

Jan

I would rather suspect something in your test runtime (transitive dependendencies of your test bundle) requires this bundle.

Hi

in my case these are UI tests for an Xtext/Xbase DSL
(http://git.eclipse.org/c/emf-parsley/org.eclipse.emf-parsley.git/tree/dsl/org.eclipse.emf.parsley.dsl.tests/pom.xml?h=tycho),
and apparently org.eclipse.osgi.compatibility.state is required (these
tests are based on a project created in the workbench during the
tests)...  I don't understand why this is not automatically loaded since
the application under test is the Eclipse workbench.  The problem goes
away if I add as extra requirement the org.eclipse.rcp feature - see
below - (which includes org.eclipse.e4.rcp which in turn includes
org.eclipse.osgi.compatibility.state in Luna).  And again this looks
strange to me since org.eclipse.rcp is part of the platform of the
running Eclipse workbench under test, so why do I need to add this
explicitly as an extra requirement?

<plugin>
	<groupId>org.eclipse.tycho</groupId>
	<artifactId>target-platform-configuration</artifactId>
	<configuration>
	<dependency-resolution>
	<extraRequirements>
	<!-- to get the org.eclipse.osgi.compatibility.state plugin iff
	the targeted Eclipse version (e.g., Luna) has it
	(backwards compatible with kepler and previous versions) -->
	<requirement>
		<type>eclipse-feature</type>
		<id>org.eclipse.rcp</id>
		<versionRange>0.0.0</versionRange>
	</requirement>
	</extraRequirements>
	</dependency-resolution>
	</configuration>
</plugin>

cheers
	Lorenzo
