Powermock+junit4单元测试

1、引入jar包

	  <dependency><groupId>org.powermock</groupId><artifactId>powermock-api-mockito2</artifactId><version>${org.powermock.version}</version><scope>test</scope></dependency><dependency><groupId>org.powermock</groupId><artifactId>powermock-module-junit4</artifactId><version>${org.powermock.version}</version><scope>test</scope></dependency>

2、对于Mockito而言，有两种方式创建：

1. mock为一个interface提供一个虚拟的实现，
2. spy为object加一个动态代理，实现部分方法的虚拟化

3、 py 和 mock不同，不同点是：

• spy 的参数是对象示例，mock 的参数是 class。
• 被 spy 的对象，调用其方法时默认会走真实方法。mock 对象不会

4、mockito 会将 @Mock、@Spy 修饰的对象自动注入到 @InjectMocks 修饰的对象中。

​ 注入方式有多种，mockito 会按照下面的顺序尝试注入：

1.  构造函数注入
1.  设值函数注入（set函数）
1.  属性注入

@RunWith(PowerMockRunner.class)
public class StockAvailableDetailRecordTest {@InjectMocksprivate RabbitProducer rabbitProducer;  // 待测试的实例对象@Mockprivate RabbitTemplate rabbitTemplate;  // 需要Mock的对象@InjectMocksprivate TenantOmsImsServiceImpl tenantOmsImsServiceImpl;@Mockprivate IWarehouseService warehouseService;@Mockprivate IStockAvailableDetailService stockAvailableDetailService;//spy 和 mock不同，不同点是：//    spy 的参数是对象示例，mock 的参数是 class。//    被 spy 的对象，调用其方法时默认会走真实方法。mock 对象不会。@Testpublic void testStockDetailRecord(){List<StockAvailableDetailRecord> records = new ArrayList<>();rabbitProducer.sendMqMessage(QueueDeclareEnum.STOCK_AVAILABLE_DETAIL_RECORD, records,"000000");}@Testpublic void testListAvailableStock(){OmsAvailableStockReqDTO omsAvailableStockReqDTO = preOmsAvailableStockReqDto();Warehouse warehouse = new Warehouse();warehouse.setId(227L);String warehouseCode = "USWEST1227";warehouse.setWarehouseCode(warehouseCode);Mockito.when(warehouseService.getWarehouseByCode(warehouseCode)).thenReturn(warehouse);GetAvailableByShopQuery query = new GetAvailableByShopQuery();query.setProductAuthId("000000");query.setProductOwnerId(0L);query.setWarehouseId(227L);query.setShopCode("amazon_US_05TK");query.setProductSku("QP80X928J9H");query.setOutputQty(1);Mockito.when(stockAvailableDetailService.addOverseaOwoAvailable(Mockito.any(), Mockito.any())).thenReturn(1);List<OwoAvailableDetailDto> availableDetails = new ArrayList<>();OwoAvailableDetailDto owoAvailableDetailDto = new OwoAvailableDetailDto();owoAvailableDetailDto.setStockId(20220106000001L);availableDetails.add(owoAvailableDetailDto);R<OmsAvailableStockReqDTO> res = tenantOmsImsServiceImpl.listAvailableStock(omsAvailableStockReqDTO);Assert.isTrue(res.isSuccess(), "fail");OmsAvailableStockReqDTO data = res.getData();}private OmsAvailableStockReqDTO preOmsAvailableStockReqDto(){OmsAvailableStockReqDTO omsAvailableStockReqDTO = new OmsAvailableStockReqDTO();ArrayList<OmsAvailableStockReqDTO.Detail> details = new ArrayList<>();omsAvailableStockReqDTO.setProductAuthId("000000");omsAvailableStockReqDTO.setDetails(details);OmsAvailableStockReqDTO.Detail detail = new OmsAvailableStockReqDTO.Detail();detail.setProductOwnerId(0L);detail.setWarehouseCode("USWEST1227");detail.setShopCode("amazon_US_05TK");detail.setProductSku("QP80X928J9H");detail.setProductQty(1);details.add(detail);return omsAvailableStockReqDTO;}}
