使用 Junit 5 测试可分页本机查询每页返回的元素比允许的多

如何解决使用 Junit 5 测试可分页本机查询每页返回的元素比允许的多

我将 Postgresql 12 与 spring-boot 2.4.5 和 spring-data 版本一起使用。

这是我的 PagingAndSortingRepository 中的查询。

    @Query(nativeQuery = true,value = "SELECT u.user_id,u.password," +
        " pgp_sym_decrypt(u.firstname," + EncryptionDetails.KEY + ") AS firstname," +
        " pgp_sym_decrypt(u.lastname," + EncryptionDetails.KEY + ") AS lastname," +
        " pgp_sym_decrypt(u.email," + EncryptionDetails.KEY + ") AS email," +
        " u.language,u.is_active,u.reset_password,u.country," +
        " pgp_sym_decrypt(u.phone_number," + EncryptionDetails.KEY + ") AS phone_number," +
        " u.last_connection,u.growing_season_id,u.category,u.pass_phrase" +
        " FROM public.\"user\" u" +
        " WHERE UPPER(UNACCENT(pgp_sym_decrypt(u.firstname," + EncryptionDetails.KEY + "))) SIMILAR TO '(_{0}|%[[:space:]]|%[[:punct:]])' || UPPER(UNACCENT(:query)) || '%'" +
        " OR UPPER(UNACCENT(pgp_sym_decrypt(u.lastname," + EncryptionDetails.KEY + "))) SIMILAR TO '(_{0}|%[[:space:]]|%[[:punct:]])' || UPPER(UNACCENT(:query)) || '%'"+
        " OR UPPER(UNACCENT(pgp_sym_decrypt(u.email," + EncryptionDetails.KEY + "))) SIMILAR TO '(_{0}|%[[:space:]]|%[[:punct:]])' || UPPER(UNACCENT(:query)) || '%'" +
        " ORDER BY lastname,firstname ASC --#pageable\n",countQuery = "SELECT count(1) " +
        " FROM public.\"user\" u" +
        " WHERE UPPER(UNACCENT(pgp_sym_decrypt(u.firstname," + EncryptionDetails.KEY + "))) SIMILAR TO '(_{0}|%[[:space:]]|%[[:punct:]])' || UPPER(UNACCENT(:query)) || '%'" +
        " OR UPPER(UNACCENT(pgp_sym_decrypt(u.email," + EncryptionDetails.KEY + "))) SIMILAR TO '(_{0}|%[[:space:]]|%[[:punct:]])' || UPPER(UNACCENT(:query)) || '%'")
Page<User> search(@Param("query") String query,Pageable pageable);

我是这样测试的：

@Test
void search_lastName() {
    Page<User> results = this.userDao.search("lAstnAme",PageRequest.of(0,2));

    assertEquals(7,results.getTotalElements(),this.logUsers(results));
    assertEquals(2,results.getNumberOfElements(),this.logUsers(results));
    assertEquals(4,results.getTotalPages(),this.logUsers(results));
}

这个测试方法在一个类中，它扩展了一个 SpringBoottest + TestContainers 类来创建一个包含数据的数据库。我应该从这个搜索中找到 7 个用户，他们应该被分成 4 个大小为 2 的页面。 该查询在运行时从我的服务调用时工作正常，但在我的测试调用时不起作用，而是返回：

results.getTotalElements() = 7
results.getNumberOfElements() = 7
results.getTotalPages() = 4
results.getSize() = 2

如果我对 Pages 的理解正确，应该是

results.getTotalElements() = 7
results.getNumberOfElements() = 2
results.getTotalPages() = 4
results.getSize() = 2

Size 如何小于 NumberOfElements？

顺便提一下，这在 Spring 1.5.19 中运行良好，但使用的是 Junit4。
