我知道为映射器或获取设置编写单元测试不是一件好事，但是，它就是这样，所以我陷入了如何为映射器进行单元测试的困境；

下面的学生组列表；

@Getter\n@Setter\npublic class StudentGroupList {\n\n private String studentId;\n}\n

下面的 StudentGroupListRowMapper；

public class StudentGroupListRowMapper implements RowMapper<StudentGroupList> {\n\n  @Override\n  public StudentGroupList mapRow(Resultset rs, int rowNum) throws SQLException {\n\n  StudentGroupList studentGroupList = new StudentGroupList();\n \n  studentGroupList.setStudentId(rs.getString("student_id"));\n\n  return studentGroupList;\n }\n}\n

我在下面尝试过，但 jococo 覆盖率测试没有覆盖任何内容

   public class TaskGroupListRowMapperTest {\n\n     private ResultSet resultSet;\n     private StudentGroupList studentGroupList;\n\n     @Before\n     public void setUp() {\n     resultSet = mock(ResultSet.class);\n     studentGroupList = mock(StudentGroupList.class);\n    }\n\n    @Test\n    public void testStudentGroupListMapper() throws SQLException {\n     when(resultSet.getString("student_id"))\n    .thenReturn(studentGroupList.getStudentID());\n     \n    assertTrue(studentGroupList.getStudentId(), true);\n …
