我有以下我要测试的方法:
public boolean sendMessage(Agent destinationAgent, String message, Supervisor s, MessagingSystem msgsys, String time) throws ParseException {
if(mailbox.getMessages().size() > 25){
return false;
}else{
if(login(s, msgsys, time)){
try {
sentMessage = msgsys.sendMessage(sessionkey, this, destinationAgent, message);
if(sentMessage.equals("OK")) {
return true;
}
return false;
} catch (ParseException e) {
e.printStackTrace();
return false;
}
}
return false;
}
}
我想模拟方法login(s, msgsys, time)
。我这样做如下:
@Mock
private Supervisor supervisor;
@Mock
private MessagingSystem msgsys;
@Test
public void testSendMessageSuccess() throws ParseException {
String message = "Hey";
Agent destination = new Agent("Alex", "2");
agent.sessionkey = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
when(agent.login(supervisor, msgsys, anyString())).thenReturn(true);
when(msgsys.sendMessage(agent.sessionkey, destination, agent, message)).thenReturn("OK");
boolean result = agent.sendMessage(destination, message, supervisor, msgsys, time);
assertEquals(true, result);
}
但是,遇到以下错误:
org.mockito.exceptions.misusing.WrongTypeOfReturnValue:
Boolean cannot be returned by getLoginKey()
getLoginKey() should return String
请注意,方法getLoginKey()
-返回字符串,在方法login(s, msgsys, time)
中调用,并且属于接口类。
@Before
public void setup(){
MockitoAnnotations.initMocks(this);
agent = new Agent("David", "1");
time = dateFormat.format(new Date());
}
@After
public void teardown(){
agent = null;
}
如果要模拟一种代理的方法之一(在您的情况下为login()
),那么您试图存根的代理需要是模拟或间谍。
因为在您的情况下登录()是您要使用代理类的其余功能完整嘲笑的唯一方法,因此您应该对此对象进行间谍:
@Before
public void setup(){
MockitoAnnotations.initMocks(this);
agent = Mockito.spy(new Agent("David", "1"));
time = dateFormat.format(new Date());
}
请注意,当固执间谍时,您需要使用以下语法:
doReturn(true).when(agent).login(supervisor, msgsys, anyString());
