如何使用EasyMock模拟受保护的方法？

Question

public class A{
    protected Integer methodA(String a){
        //some code is included;
        return new Integer(1);
    }
}
public class B extends B{
    String b = "AnyThing";
    methodA(b);
    //there are also other methods that will be tested
}

The following is partial test codes

B classUnderTest = createMockBuild(B.class).addMockedMethod(B.class.getDeclaredMethod(methodA(), String.class)).createMock;
expect(classUnderTest.methodA(anyObject(String.class))).andReturn(new Integer(1));

The second line of the second piece of code even cannot get through compile. Where is wrong?

Answer 1

Jane, regarding your main question, the line

expect(classUnderTest.methodA(anyObject(String.class))).andReturn(new Integer(1));

will compile successfully if the @Test class is in the same package as your subject under test - in this case both classes A and B (if class B extends A ). Protected instance methods are only visible to classes in the same package.

Good luck!
