覆盖范围不能覆盖public static void main方法

Question

Using Junit coverage, it can't cover public static void main method. How can I cover it?

Answer 1

After making sure it's testable just call it as any other public static method:

YourClass.main(new String[] {"parameter 1", "parameter 2"});

And assert the following state afterwards.

Answer 2

Because it does not return anything, you cannot check the output. But what does it do? If it calls another method the write a test for that method. If it doesn't call other methods, then write a test for that.
