参数匹配器的无效使用

2022-01-14 00:00:00 mockito java

下面的简单测试用例失败并出现异常.

The simple test case below is failing with an exception.

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Invalid use of argument matchers! 3 matchers expected, 2 recorded:

不知道怎么回事

@Test
public void testGetStringTest(){

    final long testId = 1;
    String dlrBAC = null;
    NamedParameterJdbcTemplate jdbcTemplate = mock(NamedParameterJdbcTemplate.class);
    when(this.dao.getNamedParameterJdbcTemplate()).thenReturn(jdbcTemplate);
    when(jdbcTemplate.queryForObject(anyString(), any(SqlParameterSource.class), String.class
                        )).thenReturn("Test");
    dlrBAC =  dao.getStringTest(testId);
    assertNotNull(dlrBAC);

}

推荐答案

Mockito 要求您在存根方法调用时仅使用原始值或仅使用匹配器.完整的例外(不是您在这里发布的)肯定可以解释一切.

Mockito requires you to either use only raw values or only matchers when stubbing a method call. The full exception (not posted by you here) surely explains everything.

简单换行:

when(jdbcTemplate.queryForObject(anyString(), any(SqlParameterSource.class), String.class
                        )).thenReturn("Test");

when(jdbcTemplate.queryForObject(anyString(), any(SqlParameterSource.class), eq(String.class)
                        )).thenReturn("Test");

它应该可以工作.
