Метод объекта mock call (Mockito Junit5 Spring)

/ 13 июля 2020

Я пытаюсь имитировать шаблонизатор тимелеафа.

Мой тестовый класс: 

@ExtendWith(MockitoExtension.class)
@RunWith(JUnitPlatform.class)
public class MailServiceTest {
    @InjectMocks
    private MailService mailService;
    
    @Mock private JavaMailSender mailSender;
    @Mock private TemplateEngine templateEngine;
    
    @BeforeEach
    public void setMockOutput() {
        doReturn("<html>Template processed String</html>").when(templateEngine.process(any(String.class), any(IContext.class)));
    }

    @Test
    public void testNewMailBoxMail() throws MessagingException, IOException {
                
        mailService.newMailBoxMail("M.", "nom", "adresse@email.fr");

        ...
    }

У меня много проблем с параметром метода процесса (org.mockito.exceptions.misusing.InvalidUseOfMatchersException), и я ' m не уверен, что они в порядке.

Когда тест достигает строки doReturn, я получаю

Может ли кто-нибудь помочь мне высмеять Thymeleaf шаблонизатор?

Спасибо, Доминик

Механизм шаблонов внедряется как bean-компонент в объект MailService. Вот код MailService: 

@Service
public class MailService {
    @Autowired private JavaMailSender mailSender;
    @Autowired private TemplateEngine templateEngine;
    
    private static final String SUPPORT_EMAIL_ADDRESS = "Support@email.fr";
    
    public void newMailBoxMail(String pCivility, String pName, String pEmailAddress) throws MessagingException {
        // template context (model)
        final Context vContext = new Context();
        vContext.setVariable("civility", pCivility);
        vContext.setVariable("name", pName);
        vContext.setVariable("email", pEmailAddress);
        
        // create HTML from template
        final String vHtmlContent = templateEngine.process("html/NewMailbox.html", vContext);
        
        // create mail
        MimeMessage vMimeMessage = mailSender.createMimeMessage();
        
        MimeMessageHelper vMessage = new MimeMessageHelper(vMimeMessage, "UTF-8");
        vMessage.setSubject("Charte messagerie");
        vMessage.setFrom(SUPPORT_EMAIL_ADDRESS);
        vMessage.setTo(pEmailAddress);
        vMessage.setText(vHtmlContent, true);
        
        // send mail
        mailSender.send(vMimeMessage);
    }
}
...
