我想使用Junit和Mockito测试此对象列表。
如果循环是如此:
List<Message> owner = new ArrayList<>();
for (int i = 0; i < messageStorage.getMessage(us.getName()).size(); i++) {
owner.add(new Message(us.getName() + " - " + messageStorage.getMessage(us.getName()).get(i).getText(),
messageStorage.getMessage(us.getName()).get(i).getTime()));
}
listOfMessages.addAll(owner);
Mockito中的测试正常工作!
@Test
public void onTheWallTest() {
when(clock.now()).thenReturn(parse("2014-12-03T10:15:30.00Z"));
User follows = new User("someFollower");
Mockito.when(userStorage.getUser(Matchers.anyString())).thenReturn(follows);
wall.onTheWall();
Mockito.verify(messageStorage).getMessage("someFollower");
}
当我以这种方式使用foreach/lambda时:
IntStream.range(0, owner.size())
.forEach(i ->
owner.add(new Message(us.getName() + " - " + messageStorage.getMessage(us.getName()).get(i).getText(),
messageStorage.getMessage(us.getName()).get(i).getTime()))
);
listOfMessages.addAll(owner);
测试因响应而失败:
Wanted but not invoked:
messageStorage.getMessage("someFollower");
-> at app.command.WallTest.onTheWallTest(WallTest.java:47)
Actually, there were zero interactions with this mock.
我修复了:
messageStorage.getMessage(us.getName())
.stream()
.map(item -> owner.add(
new Message(us.getName() + " - " + item.getText(), item.getTime())
));
