junit mockito service

言午夏2024-07-19 8:45

service类单元测试可以有两种方式

1、使用@Autowired启用上下文的Bean走业务逻辑，适用于debug调试

2、使用@InjectMocks不启用上下文依懒的Bean采用打桩的形式

打桩注意：service通常业务逻辑复杂，Bean的依懒层次可能很深，初用者常犯的问题是想一个测试方法全部测到，虽然有些可以给字段属性赋值的方法来深层次打桩，但难免会有各种各样的困难，初用者在依懒层次很深时可以把不好打桩依懒单独写单元测试

继承的基类MockBaseTest请参考本人文章[junit mockito Base基类]

java 复制代码

@RunWith(PowerMockRunner.class)
@PrepareForTest({Date.class})
public class AccountServiceTest extends MockBaseTest {
	@InjectMocks
	private AccountService accountService;
	HttpServletRequest request = new MockHttpServletRequest();

	@Before
	public void init() {
		MockitoAnnotations.initMocks(this);
	}

	@Test
	public void testAccount_check() throws Exception {
		((MockHttpServletRequest) request).setParameter("version","0.1.0");
		Date currDate = DateUtils.parse("2024-01-24 08:00:00",DateUtils.DATE_FORMATE_PATTERN);
		PowerMockito.whenNew(Date.class).withAnyArguments().thenReturn(currDate);
		AccountVO vo = accountService.queryAccount(1L, VersionUtils.getCurrVersion(request));
		Assert.assertEquals("0.1.0", vo.getVersion());
	}
