### Question:
SequenceDatabase { public int getTotalNumSeqs() { return totalNumSeqs; } SequenceDatabase(List<Sequence> sequencesToMine, int sequenceLength); int getSequenceLength(); List<Sequence> getSequences(); int getTotalNumSeqs(); TreeSet<FrequentSequenceItem> getGloballyFrequentItems(int minSupport);  }### Answer:
@Test public void totalNumSeqsTest() { assertEquals(16, database.getTotalNumSeqs()); }
