How to mock the default constructor using PowerMock with Mockito?

问题

How should I mock the default constructor using PowerMock-Mockito(No EasyMock) ?

I want to access the values of the object by doing this.

For example :

Class A {

public A()
{
}

}

PowerMockito.whenNew API should be used to perform this. See this link for further information: How to mock construction of new objects

from docs

@RunWith(PowerMockRunner.class)
@PrepareForTest(X.class)
public class XTest {
        @Test
        public void test() {
                whenNew(MyClass.class).withNoArguments().thenThrow(new IOException("error message"));

                X x = new X();
                x.y(); // y is the method doing "new MyClass()"

                ..
        }
}
