Even testing each possible option value in isolation is difficult, and most stacks don't try.

即使测试每个孤立选项值都是相当困难的，多数栈不会去尝试。

Therefore, the code that implemented the lower levels of the ACL implementation would require exceptionally careful and intricate testing and very good isolation from application programmers.

因此，执行低级ACL实现的代码需要非常仔细和复杂的测试以及与应用程序程序员的较好隔离。

In that case, you should test each component in isolation first before combining components to perform integration testing.

在这种情况下，应该首先单独测试各个组件，然后将组件组合在一起执行综合测试。
