我正在使用 mockito 验证一个方法已被调用.方法:
I'm verifying with mockito that a method has been called. The method:
public void createButtons(final List<Button> buttonsConfiguration) {...}
由于传递哪个列表并不重要,因此我验证该方法的调用如下:
Since It doesn't matter which list is passed I verify that the method is called as follows:
verify(mock).createButtons(Matchers.anyListOf(Button.class));
但是,List
的大小很重要.因此,哪个 List
并不重要,但列表必须有 X 个元素.
But, the size of the List
is important. So, it doesn't matter which List
but the list has to have X elements.
这可能吗?
一种方法是使用 Captor
One way is to use a Captor
ArgumentCaptor<List> captor = ArgumentCaptor.forClass(List.class);
verify(mock).createButtons(captor.capture());
assertEquals(x, captor.getValue().size()); // if expecting single list
assertEquals(x, captor.getValues().size()); // if expecting multiple lists
请参阅 http://docs.mockito.googlecode.com/hg/org/mockito/Mockito.html#15 获取文档.
您还可以使用自定义参数匹配器.该文档显示了一个完全符合您要求的示例:
You could also use a custom argument matcher. The documentation shows an example that does exactly what you want:
http://docs.mockito.googlecode.com/hg/org/mockito/ArgumentMatcher.html
class IsListOfTwoElements extends ArgumentMatcher<List> {
public boolean matches(Object list) {
return ((List) list).size() == 2;
}
}
List mock = mock(List.class);
when(mock.addAll(argThat(new IsListOfTwoElements()))).thenReturn(true);
mock.addAll(Arrays.asList("one", "two"));
verify(mock).addAll(argThat(new IsListOfTwoElements()));
例如,您还可以添加一个构造函数,以便指定所需的列表大小等.
You could, for instance, also add a constructor so you can specify list size desired, etc.
