Question

@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);

我想抛出代码覆盖率的Db异常。如果我将预期的例外情况指定为：Exception.class，而不是DataAccessException.class

，则其工作正常

原始课程中的方法如下：

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());
    }*

我收到错误

===============================================

Answer 1

改变这个：

thenThrow(DataAccessException.class)

到

thenThrow(new DataAccessException("..."){ })

示例：

when(userSubModuleDao.findById(any(UserSubModuleId.class),eq(false))).thenThrow(new DataAccessException("..."){});

当Exception类型具有No-Arg构造函数时，您只能传递Class引用，而Spring异常没有。

Answer 2

尝试

Mokito.doThrow（new Exception（））。when（mockedObject）.methodName（...）;

Answer 3

如仁恩（Jen S）所述：

仅当该Exception类型具有No-Arg构造函数且Spring异常不具有Class引用时，才可以传递Class引用。

我的解决方案是使用Mockito：

library(ggplot2)
df1 <- data.frame(x = 1 : 10, y = rnorm(10))
df2 <- data.frame(x = 1 : 10, y = runif(10))

g <- ggplot()
g <- g + geom_point(aes(x = x, y = y, color = 'color1'), 
                    data = df1, shape = 19, size = 2)
g <- g + geom_point(aes(x = x, y = y, color = 'color2'), 
                    data = df2, shape = 17, size = 3)
g + scale_colour_manual(breaks = c('color1', 'color2'), 
                        values = c('color1' = 'blue', 'color2' = 'red'),
                        guide = guide_legend(override.aes = list(shape = c(19, 17))))
