Mockito mock constructor example

Question

I'm trying to instantiate a mock object with Mockito. I found two examples in the article here, still this article is a very bad example for a newbie like me in Mockito.

Can somebody give me a better example of how it is done with either of the two options?

Answer 1

Simple when doing PowerMockito

public class A {
    private final String name;

    public A(String name) {
        this.name= name;
    }

    public String sayHello() {
        return "Hi " + this.name;
    }}

@RunWith(PowerMockRunner.class)
@PrepareForTest(A.class)
public class MockA {

    @Test
    public void testSayHello throws Throwable {
         A a = mock(A.class); 
         when(a.sayHello()).thenReturn("Hi PowerMockito");
         PowerMockito.whenNew(A.class).withArguments(Mockito.anyString()).thenReturn(a);
         assertThat(new A("I am mockcked").sayHello(), equalTo("Yes, you are!"));
    }
}
