### Question:
MongoTokenStore implements TokenStore { @Override public boolean requiresExplicitSegmentInitialization() { return true; } protected  MongoTokenStore(Builder builder); static Builder builder(); @Override void storeToken(TrackingToken token, String processorName, int segment); @Override void initializeTokenSegments(String processorName, int segmentCount); @Override void initializeTokenSegments(String processorName,
                                        int segmentCount,
                                        TrackingToken initialToken); @Override TrackingToken fetchToken(String processorName, int segment); @Override void extendClaim(String processorName, int segment); @Override void releaseClaim(String processorName, int segment); @Override void initializeSegment(TrackingToken token,
                                  String processorName,
                                  int segment); @Override void deleteToken(String processorName, int segment); @Override boolean requiresExplicitSegmentInitialization(); @Override int[] fetchSegments(String processorName); @Deprecated void ensureIndexes();  }### Answer:
@Test void testRequiresExplicitSegmentInitializationReturnsTrue() { assertTrue(tokenStore.requiresExplicitSegmentInitialization()); }
