单元测试验证通过被调用的功能

比方说，我有这个功能（写在Kotlin）：

fun determineBottomBarView(assignee: String?, showChatAssignerFunction: () -> Unit, showChatComposerFunction: () -> Unit, hideChatComposerAndAssignerFunction: () -> Unit) { if (assignee.isNullOrEmpty()) { showChatAssignerFunction() } else { if (assignee.equals(localRequestManager.getUsername())) { showChatComposerFunction() } else { hideChatComposerAndAssignerFunction() } } } 

当受让人为空或空时，是否可以验证（在单元测试中） showChatAssignerFunction是否被调用？ 谢谢你们！

你当然可以：

 @Test fun `just testing`() { var showedChatAssigner = false var showChatComposer = false var didHideChat = false determineBottomBarView(null,{ showedChatAssigner = true }, { showChatComposer = true }, { didHideChat = true }) assertThat(showedChatAssigner, equalTo(true)) assertThat(showChatComposer, equalTo(false)) assertThat(didHideChat, equalTo(false)) }
