That is, we no longer check that the final balance of the test account is correct; we would check that function in the unit test for the Transaction object, not the AtmGui object.

As an example to show how an alternative combination fragment is read, Figure 8 shows the sequence starting at the top, with the bank object getting the check's amount and the account's balance.

图8作为一个变体的组合碎片如何阅读的例子，显示序列从顶部开始，即bank对象获取支票金额和帐户结余。
