将 JdbcTemplate 更新方法与 Mockito 匹配

Question

我正在尝试匹配我在 Dao 类中使用的这种方法。但我总是收到以下异常，表明未在该方法上进行调用。

要么方法不匹配，要么我做错了什么。

String pSql = "SELECT * FROM employee";
Object[] pArgs = new Object[] {""};
int[] pArgTypes =  new int[] {};

/* Return 1 when the call to update() is made indicating a successful database update */
when(mJdbcTemplate.update(anyString(), aryEq(pArgs), aryEq(pArgTypes))).thenReturn(1);

这是异常的堆栈跟踪：

Wanted but not invoked:
jdbcTemplate.update(<any>, <any>, <any>);
-> at com.test.GenericDaoJdbcImplTest$WhenInsertUpdateDeleteIsCalledWith.successfulUpdateShouldReturnTrue(GenericDaoJdbcImplTest.java:197)

However, there were other interactions with this mock:
-> at com.test.GenericDaoJdbcImplTest.insertUpdateDelete(GenericDaoJdbcImpl.java:121)

MyGenericDaoJdbcImplTest是一个抽象类。这是我正在测试的课程。

public abstract class GenericDaoJdbcImpl<MODEL, PRIMARYKEY extends Serializable>
        implements GenericJdbcDao<MODEL, PRIMARYKEY> {

    @Autowired
    @Qualifier(value = "jdbcTemplate")
    private JdbcTemplate mJdbcTemplate;

    private Class<MODEL> mType;

    public JdbcTemplate getJdbcTemplate() {
        return mJdbcTemplate;
    }

    public void setJdbcTemplate(final JdbcTemplate pJdbcTemplate) {
        this.mJdbcTemplate = pJdbcTemplate;
    }

    public GenericDaoJdbcImpl(final Class<MODEL> pType) {
        this.mType = pType;
    }

    public abstract MODEL add(final MODEL mModel);

    public abstract MODEL modify(final MODEL mModel);

    public abstract MODEL read(PRIMARYKEY pId);

    public abstract List<MODEL> list();

    public abstract void delete(PRIMARYKEY pId);

    @Override
    public boolean insertUpdateDelete(final String pSql, final Object[] pArgs,
            final int[] pArgTypes) {

        Assert.hasLength(pSql, "No SQL provided to execute");
        Assert.notNull(pArgs, "No data provided to insert/update/delete");
        Assert.notNull(pArgTypes, "No data types provided for");
        Assert.isTrue(pArgs.length == pArgTypes.length, "Mis-match in data and data type count");

        return (mJdbcTemplate.update(pSql, pArgs, pArgTypes) > 0);
    }
}

您必须在when调用中强制转换参数。否则参数将不明确，编译器无法将其解析为特定update方法。

所以：

Mockito.when(jdbcTemplate.update((String)Mockito.anyString(), (Object[])Mockito.anyVararg())).thenReturn(var);

应该可以解决您的问题。至少对我来说是这样。
