对私有静态方法进行单测

1.被单测的类：

/** * Created by 58 on 2016-8-21. */public class Student {    private static String reading(String bookName) {       return "student read " + bookName;    }}

2.使用junit方式

@Test    public void readingTest() {        String expected = "student read ";        String input = "Thinking in java";        try {            Method targetMethod = Student.class.getDeclaredMethod("reading", String.class);            targetMethod.setAccessible(true);            Object actual = targetMethod.invoke(Student.class, input);            assertEquals(expected + input, actual);        }catch (Exception e) {            fail("单测异常");        }    }
