这个互操作性测试有助于在各个栈之间建立基本水平的兼容性，但是收效甚微，因为只有少量配置被测试。

This interoperability testing has helped establish a basic level of compatibility among stacks, but the benefits have been limited because of the small number of configurations tested.

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。

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

这么多的可行配置，没有web服务栈能将它们全部测试。

With so many possible configurations, no web services stack can possibly test them all.
