我想，一些简单的重构可以在没有单元测试的情形下进行。

I imagine some simple refactorings can be performed even without unit testing in place.

在某些情况下，重构可能改变单元测试本身，但重要的是这也应该是自动发生的。

In some cases, the unit tests themselves may be changed by the refactoring, but the point is that this should happen automatically as well.

图2显示了在Log选项卡下的单元测试统计数据(单击这里可以看到图2的放大图)。
