[英]Mockito throw Exception
@Test(expectedExceptions=DataAccessException.class)
public void testUpdateSubModuleOrderDateExceptionCheck() {
//some code to initialize//
UserSubModuleDao userSubModuleDao = mock(UserSubModuleDao.class);
userModuleServiceImpl.setUserSubModuleDao(userSubModuleDao);
UserSubModule userSubModule=new UserSubModule();
UserSubModuleId userSubModuleId=new UserSubModuleId();
when(userSubModuleDao.findById(any(UserSubModuleId.class),eq(false))).thenThrow(DataAccessException.class);
userModuleServiceImpl.updateSubModuleOrder(data, moduleSysId, userId);
I want to throw the Db exception for code coverage .我想为代码覆盖率抛出 Db 异常。 its working if i give expected exception as : Exception.class
but not for DataAccessException.class
如果我将预期的异常作为: Exception.class
但不适用于DataAccessException.class
它的工作
My method in original class is as following:我在原始类中的方法如下:
public void updateSubModuleOrder(Long[] data, Long moduleSysId, Long userId) {
try {
for (int i = 0; i < data.length; i++) {
SubModule subModule=new SubModule();
subModule.setSubModuleId(data[i]);
UserSubModuleId userSubModuleId = new UserSubModuleId();
userSubModuleId.setSubModuleId(subModule);
userSubModuleId.setUserId(userId);
userSubModuleId.setUserModuleId(moduleSysId);
UserSubModule userSubmodule = new UserSubModule();
userSubmodule = userSubModuleDao.findById(userSubModuleId,
false);
catch (DataAccessException ewmsDataExp) {
LOGGER.error(
"Database Exception while updateSubModuleOrder because of {}",
ewmsDataExp.getMessage());
throw new EWMSServiceException(
"Database Exception while updateSubModuleOrder"
+ ewmsDataExp.getMessage());
} catch (Exception exp) {
LOGGER.error(
"System Exception while updateSubModuleOrder because of {}",
exp.getMessage());
throw new EWMSServiceException(
"Database Exception while updateSubModuleOrder"
+ exp.getMessage());
}*
i get the error我得到了错误

Change this:改变这个:
thenThrow(DataAccessException.class)
to到
thenThrow(new DataAccessException("..."){ })
Example:例子:
when(userSubModuleDao.findById(any(UserSubModuleId.class),eq(false))).thenThrow(new DataAccessException("..."){});
You can only pass a Class reference when that Exception type has a No-Arg constructor, and the Spring exception does not have one.您只能在该异常类型具有 No-Arg 构造函数时传递 Class 引用,而 Spring 异常没有。
尝试
Mockito.doThrow(new Exception()).when(mockedObject).methodName(...);
As stated by Jen S:正如 Jen S 所说:

My solution was using Mockito:我的解决方案是使用 Mockito:
Mockito.when(mockedObject.method(Mockito.anyString())).thenThrow(Mockito.mock(DataAccessException.class));
