嗨，我有一个mock方法templateEngine.produce(…(.的问题
public class MailTemplateCreator {
private final TemplateEngine templateEngine;
public MailTemplateCreator(@Qualifier("templateEngine") TemplateEngine templateEngine) {
this.templateEngine = templateEngine;
}
/** Method for inject variables for thymeleaf html template.
* @param values class for inject values for thymeleaf context.
* @return values inject into Email-alert-template.html.
*/
public String buildEmailTemplate(TemplateValues values){
Context context = new ContextBuilder()
.addVariable("topic",EmileMassages.topic(values.getChangedData()))
.addVariable("welcome",EmileMassages.welcome(values.getName()))
.addVariable("message",EmileMassages.message(values.getChangedData(),values.getDataValue()))
.addVariable("button",EmileMassages.buttonName(values.getChangedData()))
.addVariable("change_url",EmileMassages.changeLink(values.getChangeDataLink()))
.addVariable("goodbye", EmileMassages.goodbye())
.addVariable("app_name",EmileMassages.appName()).build();
return templateEngine.process("email/Email-alert-template.html",context);
}
}
class MailTemplateCreatorTest {
@InjectMocks
MailTemplateCreator creator;
@Mock
TemplateEngine templateEngine;
@Test
void name() {
//Given
TemplateValues values = TemplateValues.builder()
.changeDataLink("test link")
.changedData("test Data")
.dataValue("test value")
.name("test name").build();
when(templateEngine.process("email/Email-alert-template.html",any(Context.class))).thenReturn("Test");
//When
String emailHtml =creator.buildEmailTemplate(values);
//Then
assertThat(emailHtml).isNotEmpty();
}

实际上，GitHub上早就报道过这个。问题是mockito没有嘲笑最终方法(这是有道理的(。解决方案是使用ITemplateEngine接口，如果我理解正确的话，它是自Thymelaf 3.0以来提供的。
将类的实现从public MailTemplateCreator(@Qualifier("templateEngine") TemplateEngine templateEngine)更改为public MailTemplateCreator(@Qualifier("templateEngine") ITemplateEngine templateEngine)，并模拟接口@Mock ITemplateEngine templateEngine;。
现在，您可以随心所欲地存根，例如when(templateEngine.process(anyString(),any(Context.class))).thenReturn("Test");。
