这是我最初尝试使用 JMockIt 时发现的。我必须承认,我发现 JMockIt 文档对于它提供的内容非常简洁,因此我可能遗漏了一些东西。尽管如此,这是我的理解:
Mockito: List a = mock(ArrayList.class) does not stub out all methods
of List.class by default. a.add("foo") is going to do the usual thing
of adding the element to the list.
JMockIt: @Mocked ArrayList<String> a;
It stubs out all the methods of a by default. So, now a.add("foo")
is not going to work.
This seems like a very big limitation to me in JMockIt.
How do I express the fact that I only want you to give me statistics
of add() method and not replace the function implementation itself
What if I just want JMockIt to count the number of times method add()
was called, but leave the implementation of add() as is?
I a unable to express this in JMockIt. However, it seems I can do this
in Mockito using spy()
我真的很想在这里被证明是错误的。JMockit 声称它可以做其他模拟框架所做的一切以及更多。好像不是这里的情况
@Test
public void shouldPersistRecalculatedArticle()
{
Article articleOne = new Article();
Article articleTwo = new Article();
when(mockCalculator.countNumberOfRelatedArticles(articleOne)).thenReturn(1);
when(mockCalculator.countNumberOfRelatedArticles(articleTwo)).thenReturn(12);
when(mockDatabase.getArticlesFor("Guardian")).thenReturn(asList(articleOne, articleTwo));
articleManager.updateRelatedArticlesCounters("Guardian");
InOrder inOrder = inOrder(mockDatabase, mockCalculator);
inOrder.verify(mockCalculator).countNumberOfRelatedArticles(isA(Article.class));
inOrder.verify(mockDatabase, times(2)).save((Article) notNull());
}
@Test
public void shouldPersistRecalculatedArticle()
{
final Article articleOne = new Article();
final Article articleTwo = new Article();
new Expectations() {{
mockCalculator.countNumberOfRelatedArticles(articleOne); result = 1;
mockCalculator.countNumberOfRelatedArticles(articleTwo); result = 12;
mockDatabase.getArticlesFor("Guardian"); result = asList(articleOne, articleTwo);
}};
articleManager.updateRelatedArticlesCounters("Guardian");
new VerificationsInOrder(2) {{
mockCalculator.countNumberOfRelatedArticles(withInstanceOf(Article.class));
mockDatabase.save((Article) withNotNull());
}};
}
像这样的声明
inOrder.verify(mockDatabase, times(2)).save((Article) notNull());
在 Mockito 中,在 JMockIt 中没有等效项,正如您从上面的示例中看到的那样
new NonStrictExpectations(Foo.class, Bar.class, zooObj)
{
{
// don't call zooObj.method1() here
// Otherwise it will get stubbed out
}
};
new Verifications()
{
{
zooObj.method1(); times = N;
}
};
