### Question:
LoopPerformances implements Serializable { public int numberOfTests() { return list.size(); } @SuppressWarnings("unchecked") private  LoopPerformances();  LoopPerformances(final long iterations,
            final Map<String, Long> timeMap); int numberOfTests(); TestPerformances getPerformancesFor(final String msg); List<TestPerformances> getTests(); long getIterations(); Statistics getStatistics(); List<Long> getElapsedNanosecondsList(); List<String> getNameList(); List<Double> getNanosecondsPerCycleList(); List<Float> getPercentageList(); float getPercentageFor(final String name); String toString(final String message); @Override String toString(); @SuppressWarnings("unchecked")
    static final LoopPerformances EMPTY; }### Answer:
@Test public void shouldGetTheSize() { assertEquals(3, loopPerformances.numberOfTests()); }
