试图使用mockito对一个函数进行junit测试，该函数需要调用同一类的另一个函数，得到org.openest4j.A

Question

假设我有两个这样的函数：(我不想共享实际的代码，它非常巨大(

public class EmailService{
String addressList1 = "[e-mail],[e-mail]";
public String[] getAddressList(String addressList){
return addressList.split(",");
}
public int getNumber(){
for (String address : getAddressList(addressList1))
{
if (address.equals("[e-mail]")){return 1;}
}
return 0;
}
}

我在测试getNumber((函数时尝试了这个：

EmailService emailService1 = new EmailService();
EmailService emailService2 = Mockito.spy(emailService1);
String deliveryAddress = "[e-mail],[e-mail]";       
doReturn(deliveryAddress.split(",")).when(emailService2).getAddressList(deliveryAddress);
assertEquals(EmailService2.getNumber(), 1);

但我得到了：org.openest4j.AssertionFailedError:空

Answer 1

我找到了答案。

由于addressList1是一个局部变量，所以在调用getNumber函数之前，我必须设置它的值。

ReflectionTestUtils.setField(emailService2, "addressList1","[e-mail],[e-mail]");
