### Question:
IsotopePattern { public IsotopePattern() { } IsotopePattern(); void setMonoIsotope(IsotopeContainer isoContainer); void addIsotope(IsotopeContainer isoContainer); IsotopeContainer getMonoIsotope(); List<IsotopeContainer> getIsotopes(); IsotopeContainer getIsotope(int position); int getNumberOfIsotopes(); void setCharge(double charge); double getCharge(); @Override Object clone();  }### Answer:
@Test public void testIsotopePattern() { IsotopePattern isoP = new IsotopePattern(); Assert.assertNotNull(isoP); }
