如何验证父类的super.method()的调用？

Question

我有三个非常简单的课程.其中一个扩展了父类.

public class Parent{
    protected String print() {
        // some code
    }
}

这是一个儿童班.

public class Child extends Parent {
    /**
     * Shouldn't invoke protected Parent.print() of parent class.
     */
    @Override
    protected String print() {
        // some additional behavior
        return super.print();
    }
}

和测试班.

public class ChildTest {

    @Test
    public void should_mock_invocation_of_protected_method_of_parent_class() throws Exception {

        // Given
        Child child = PowerMockito.mock(Child.class);
        Method method = PowerMockito.method(Parent.class, "print");
        PowerMockito.when(child, method).withNoArguments().thenReturn("abc");

        // When
        String retrieved = child.print();

        // Than
        Mockito.verify(child, times(1)).print(); // verification of child method
        Assert.assertEquals(retrieved, "abc");
    }
}

我需要验证super.print()调用.我该怎么做？

Answer 1

如果你调用super.print()Child类的print()方法，当然print()会调用Parent类的实现。如何验证它是否确实发生取决于父类实现实际执行的操作。

PS你代码中的注释Shouldn't invoke protected Parent.print() of parent class是Parent.print() method shouldn't be invoked.错误的。
