英文:
Correctly mock a service method which returns a javax.mail.Message
问题
我有一个名为EmailScanner.java的类，其中有以下代码：
@Autowired
@Qualifier("customClient")
private EmailClient client; //EmailClient是一个接口
我正试图为上述类编写一个测试，并对客户端进行如下模拟。
@InjectMocks
private EmailScanner emailScanner;
@Mock
@Qualifier("customClient")
private EmailClient client;
在客户端中，我有一个方法用于读取并返回电子邮件。 client.fetchEmail(folderName)。
我已经编写了 Mockito.doReturn(getSampleMessage()).when(client).fetchEmail(Mockito.anyString());。
getSampleMessage() 从磁盘中读取 .eml 文件并将其转换为邮件消息，但在运行时我得到了空消息。我是否漏掉了什么，或者在这里做错了什么？
英文:
I have an EmailScanner.java class which has
@Autowired
@Qualifier("customClient")
private EmailClient client; //EmailClient is interface
I am trying to write a test for above class and mocking the client as shown below.
@InjectMocks
private EmailScanner emailScanner;
@Mock
@Qualifier("customClient")
private EmailClient client;
in the client, I have a method that reads and returns an Email. client.fetchEmail(folderName).
I have written Mockito.doReturn(getSampleMessage()).when(client).fetchEmail(Mockito.anyString());.
getSampleMessage() reads .eml file from disk and convert it into Mail message, on running i am getting null message. Is there anything i am missed on or doing wrong here?
