测试需要在Java中使用同一类的其他方法的方法

import org.junit.Test;
import static org.junit.Assert.*;

public class MyClassTest {
    
    @Test
    public void testMethod1() {
        MyClass myClass = new MyClass();
        int result = myClass.method1();
        assertEquals(10, result);
    }
    
    @Test
    public void testMethod2() {
        MyClass myClass = new MyClass();
        int result = myClass.method2();
        assertEquals(20, result);
    }
}

import java.lang.reflect.Method;
import static org.junit.Assert.*;

public class MyClassTest {
    
    @Test
    public void testMethod1() throws Exception {
        MyClass myClass = new MyClass();
        Method method = MyClass.class.getDeclaredMethod("method1");
        method.setAccessible(true);
        int result = (int) method.invoke(myClass);
        assertEquals(10, result);
    }
    
    @Test
    public void testMethod2() throws Exception {
        MyClass myClass = new MyClass();
        Method method = MyClass.class.getDeclaredMethod("method2");
        method.setAccessible(true);
        int result = (int) method.invoke(myClass);
        assertEquals(20, result);
    }
}

import static org.junit.Assert.*;

public class MyClassTest {
    
    @Test
    public void testMethod1() {
        MyClass myClass = new MyClass();
        InnerClass innerClass = myClass.new InnerClass();
        int result = innerClass.method1();
        assertEquals(10, result);
    }
    
    @Test
    public void testMethod2() {
        MyClass myClass = new MyClass();
        InnerClass innerClass = myClass.new InnerClass();
        int result = innerClass.method2();
        assertEquals(20, result);
    }
    
    private class InnerClass {
        
        public int method1() {
            return MyClass.this.method1();
        }
        
        public int method2() {
            return MyClass.this.method2();
        }
    }
}
