我有问题断言由LocalDateTime.now()方法产生的时间,我想断言整个查询而忽略它产生的时间。 以下是代码:
jQuery 1.12.4
以下是比较失败的详细信息,因此您可以更加了解我需要忽略的内容:Comparison Failure Window Screenshot.
以下是我正在测试的方法:
@Test
public void getLastDrawResult_lotteryIdPresent() {
Optional<Long> lotteryId = Optional.of(3L);
Optional<String> name = Optional.empty();
Optional<String> byName = Optional.empty();
Optional<String> byDate = Optional.empty();
Optional<Boolean> jackpotOnly = Optional.empty();
String query = QUERY_MAIN_BLOCK.replace("/*statement0*/", LocalDateTime.now().plusMinutes(buyingLock).toString()) + CONDITION_SEARCH_BY_LAST_DRAW_RESULT;
String updatedQuery = query.replace("/*statement1*/", " WHERE d.lottery_info_id = 3") + " AND d.lottery_info_id = 3";
DrawResultDto drawResultDto = DrawResultDto.builder().id(3L).build();
List<DrawResultDto> expectedDrawResultDto = singletonList(drawResultDto);
when(jdbcTemplate.query(updatedQuery, drawResultDtoQueryBuilder.queryMapper)).thenReturn(expectedDrawResultDto);
List<DrawResultDto> actualDrawResultDto = drawResultDtoQueryBuilder.getLastDrawResult(lotteryId, name, byName, byDate, jackpotOnly);
verify(jdbcTemplate).query(updatedQuery, drawResultDtoQueryBuilder.queryMapper);
assertEquals(expectedDrawResultDto, actualDrawResultDto);
我试图从Mockito做匹配(),没有运气。我似乎无法让正则表达式工作。喜欢匹配一切但是下面的正则表达式:public List<DrawResultDto> getLastDrawResult(Optional<Long> lotteryId, Optional<String> name, Optional<String> byName, Optional<String> byDate, Optional<Boolean> jackpotOnly) {
String query = QUERY_MAIN_BLOCK.replace("/*statement0*/", LocalDateTime.now().plusMinutes(buyingLock).toString()) +
CONDITION_SEARCH_BY_LAST_DRAW_RESULT;
StringBuilder builder = new StringBuilder();
if (lotteryId.isPresent()) {
builder.append(query.replace("/*statement1*/", " WHERE d.lottery_info_id = " + lotteryId.get()))
.append(String.format(" AND d.lottery_info_id = %d", lotteryId.get()));
} else {
builder.append(query);
name.ifPresent(nameValue -> builder.append(" AND lower(li.name) LIKE '%").append(SqlUtils.escapeLike(nameValue).toLowerCase()).append("%' "));
jackpotOnly.ifPresent(jackpotOnlyValue -> {
if (jackpotOnlyValue) {
builder.append(" AND ").append(CONDITION_SEARCH_BY_JACKPOT_WIN);
}
});
byName.ifPresent(s -> builder.append(" ORDER BY li.name ").append(SqlUtils.escapeLike(s)));
byDate.ifPresent(s -> builder.append(" ORDER BY nfd.nearestDrawDate ").append(SqlUtils.escapeLike(s)));
if (!byName.isPresent() && !byDate.isPresent()){
builder.append(" ORDER BY li.name desc ");
}
}
return jdbcTemplate.query(builder.toString(), queryMapper);
}
。选择我需要忽略的部分。

好像你在代码之后编写测试:p(否则你就不会遇到这样的问题)。
我要做的是将localedatetime传递给函数,以便您可以对它进行单元测试:
public List<DrawResultDto> getLastDrawResult(LocalDateTime t, Optional<Long> lotteryId, Optional<String> name, Optional<String> byName, Optional<String> byDate, Optional<Boolean> jackpotOnly) {
String query = QUERY_MAIN_BLOCK.replace("/*statement0*/", t.plusMinutes(buyingLock).toString()) +
[...]
}
并保持与现有代码的一致性,保留实际签名:
public List<DrawResultDto> getLastDrawResult(Optional<Long> lotteryId, Optional<String> name, Optional<String> byName, Optional<String> byDate, Optional<Boolean> jackpotOnly) {
return getLastDrawResult(LocaleDateTime.now(), Optional<Long> lotteryId, Optional<String> name, Optional<String> byName, Optional<String> byDate, Optional<Boolean> jackpotOnly);
}
现在你可以正确地测试第一种方法(通过传递一个在测试方法中构建的localedatetime),单元测试第二种方法是微不足道的。

此处的最佳做法将涉及您注入Clock,这将允许您通过覆盖now
方法访问所需的任何对象(包括LocalDateTime)。
public List<DrawResultDto> getLastDrawResult(
Optional<Long> lotteryId,
Optional<String> name,
Optional<String> byName,
Optional<String> byDate,
Optional<Boolean> jackpotOnly,
Clock clock) {
LocalDateTime localDateTime = LocalDateTime.now(clock);
/* ... */
}
与Ash's answer中一样,您可以使用当前签名创建新SystemClock的方法重载,然后测试接受时钟的方法。
/** Your original method signature. No changes to any calling code. */
public List<DrawResultDto> getLastDrawResult(
Optional<Long> lotteryId,
Optional<String> name,
Optional<String> byName,
Optional<String> byDate,
Optional<Boolean> jackpotOnly) {
return getLastDrawResult(lotteryId, name, byName, byDate, jackpotOnly,
Clock.systemDefaultZone());
}
/** Your original method implementation. Test this one. */
public List<DrawResultDto> getLastDrawResult(
Optional<Long> lotteryId,
Optional<String> name,
Optional<String> byName,
Optional<String> byDate,
Optional<Boolean> jackpotOnly,
Clock clock) {
LocalDateTime localDateTime = LocalDateTime.now(clock);
/* ... */
}
这样,在测试中,您可以传递Clock.fixed
的值。
另外,您应该强烈考虑将此方法切换为参数化查询JdbcTemplate supports natively。你甚至可以support named parameters using related classes。
