你好，我有一个问题与模拟方法templateEngine.process（...）。

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();
    }
