### Question:
BondEnergy { public synchronized IBond.Order getBondOrder() { return bondOrder; } BondEnergy(String symbol1, String symbol2,
            IBond.Order order, int energy); synchronized String getSymbolFirstAtom(); synchronized String getSymbolSecondAtom(); synchronized IBond.Order getBondOrder(); synchronized int getEnergy(); synchronized boolean matches(IBond bond);  }### Answer:
@Test public void testGetBondOrder() { BondEnergy instance = new BondEnergy("H", "I", Order.SINGLE, 295); Order expResult = Order.SINGLE; Order result = instance.getBondOrder(); assertEquals(expResult, result); }
