单元测试私有方法:Facade模式

public class MyClass {
    private String myPrivateMethod(String input) {
        // 实现私有方法的代码
    }

    public String myPublicMethod(String input) {
        return myPrivateMethod(input);
    }
}

public class MyClassFacade {
    private MyClass myClass;

    public MyClassFacade(MyClass myClass) {
        this.myClass = myClass;
    }

    public String callMyPrivateMethod(String input) {
        return myClass.myPrivateMethod(input);
    }
}

public class MyClassTest {
    @Test
    public void testMyPrivateMethod() {
        MyClass myClass = new MyClass();
        MyClassFacade myClassFacade = new MyClassFacade(myClass);

        String result = myClassFacade.callMyPrivateMethod("input");

        // 对结果进行断言
        assertEquals("expected", result);
    }
}
