Java 测试生成器模式

我正在尝试对一个生成器样式的模式进行单元测试，该模式如下所示（mockedObject被注入到函数中，因此我可以对其进行模拟）：

我正在尝试解决如何在不模拟整个构建器对象的情况下测试（使用JUnit和Easymock）。我只需要在结果对象上测试

param1

和

param2

是否设置了特定值

模拟整个构建器模式会使测试非常脆弱，而这不是我应该首先测试的

有没有（更好的）方法来测试这一点？

通过Mokito和JUnit5，您可以在模拟中使用RETURNS\u DEEP\u存根。例如，以下是一个示例：

@ExtendWith(MockitoExtension.class)
@RunWith(JUnitPlatform.class)
class TargetClassTest {
 private static final long SUBJECT_ID;


 @Mock 
 private AuthService authService;

 @Mock(answer = Answers.RETURNS_DEEP_STUBS)  // deeply stubbed
 private Logger logger;

 @InjectMocks
 private TargetClass service;


 @Test
 void test_whenSomething_thenResult() {
    service.command(SUBJECT_ID);

    verify(logger,times(1)).builder(eq(SUBJECT_ID));
    verify(loggerbuilder(eq(SUBJECT_ID)),times(1)).thirdPartyLog(eq(DATA_DOG));
    verify(loggerbuilder(eq(SUBJECT_ID)).thirdPartyLog(DATA_DOG),times(1)).send();

 }


}

正如您在上面所看到的，我为构建器创建了一个留有很深存根的模拟，然后我可以确保使用适当的参数正确地调用它

@ExtendWith(MockitoExtension.class)
@RunWith(JUnitPlatform.class)
class TargetClassTest {
 private static final long SUBJECT_ID;


 @Mock 
 private AuthService authService;

 @Mock(answer = Answers.RETURNS_DEEP_STUBS)  // deeply stubbed
 private Logger logger;

 @InjectMocks
 private TargetClass service;


 @Test
 void test_whenSomething_thenResult() {
    service.command(SUBJECT_ID);

    verify(logger,times(1)).builder(eq(SUBJECT_ID));
    verify(loggerbuilder(eq(SUBJECT_ID)),times(1)).thirdPartyLog(eq(DATA_DOG));
    verify(loggerbuilder(eq(SUBJECT_ID)).thirdPartyLog(DATA_DOG),times(1)).send();

 }
