### Question:
FastqToSsake implements Callable<Integer> { static boolean isLeft(final Fastq fastq) { return LEFT.matcher(fastq.getDescription()).matches(); } FastqToSsake(final File firstFastqFile, final File secondFastqFile, final File ssakeFile, final int insertSize, final File unpairedFile); @Override Integer call(); static void main(final String[] args); static final int DEFAULT_INSERT_SIZE; }### Answer:
@Test public void testIsLeft() { for (Fastq fastq : LEFT) { assertTrue(isLeft(fastq)); } for (Fastq fastq : RIGHT) { assertFalse(isLeft(fastq)); } for (Fastq fastq : INVALID) { assertFalse(isLeft(fastq)); } }
