### Question:
Version implements Comparable<Version> { public Version getTransition(Version destination) { if (!(version instanceof VersionComponent)) { throw new UnsupportedOperationException("Source version does not represent a single version"); } if (!(destination.version instanceof VersionComponent)) { throw new UnsupportedOperationException("Destination version does not represent a single version"); } final org.osgi.framework.Version currentVersion = (org.osgi.framework.Version) version.get(); final String oldQualifier = currentVersion.getQualifier(); final String newQualifier; if (StringUtils.isEmpty(oldQualifier)) { newQualifier = "transition"; } else { newQualifier = oldQualifier + "-transition"; } return new Version( new org.osgi.framework.Version( currentVersion.getMajor(), currentVersion.getMinor(), currentVersion.getMicro(), newQualifier ) ); } protected  Version(String value); protected  Version(org.osgi.framework.Version version); protected  Version(Component<?> version); static Version lookup(String value); final boolean isTransition(); Version getNext(); Version getTransition(Version destination); Version get(int index); Version get(String key); Version replace(int index, Version element); Version replace(String key, Version element); @Override String toString(); @Override boolean equals(Object o); @Override int hashCode(); @Override int compareTo(Version other); static final Version INITIAL; }### Answer:
@Test(groups = { TestGroups.UNIT }, dataProvider = "transitions") public void testGetTransition(Version source, Version destination, Version expected) { Assert.assertEquals(source.getTransition(destination), expected); }
