mockito 外部接口_使用Mockito测试接口方法

我正在为通过接口在内部调用另一个方法的方法编写JUnit测试用例。我使用Mockito来模拟界面，但由于某种原因它给了我NPE。我调试通过，但无法得到任何线索来解决它。 getAllVendors()方法抛出通过接口传入的异常。使用Mockito测试接口方法

MUT

public void prepare() throws AccountServiceException, ManagerException {

vendors = getVendorManager().getAllVendors();

microsites = new ArrayList();

microsites.add(new VendorMicrositeTO("http://www.docusign.com", "docuSign"));

clientUser = createClientUserObject();

}

的JUnit

@Test

public void testPrepare() throws Exception {

AccountAction accountAction = new AccountAction();

Map actionMap = new HashMap<>();

actionMap.put("application", "ESignatureIntegrationAction");

ActionContext.setContext(new ActionContext(actionMap));

String beanName = Constants.VENDOR_MANAGER_SPRING_BEAN;

PowerMockito.mockStatic(AppContext.class);

PowerMockito.when(AppContext.containsBean(beanName)).thenReturn(true);

IVendorDto iVendorDto = new VendorDto();

iVendorDto.setActive(true);

iVendorDto.setCreatedBy("9/15/2016");

iVendorDto.setName("CorpESignClientUser");

iVendorDto.setCreatedBy("SYSTEM");

List vendorList = new ArrayList<>();

vendorList.add(iVendorDto);

IVendorManager iManager = Mockito.mock((IVendorManager.class));

Mockito.when(iManager.getAllVendors()).thenReturn(vendorList);

accountAction.setVendors(vendorList);

accountAction.prepare();

}
