AssertJ的"usingComparatorForFields"如何工作? [英] How does AssertJ's `usingComparatorForFields` work?

问题描述

与如何使用assertJ进行递归忽略给定字段的比较?

作为解决此问题的方法，我尝试为不希望比较器进行比较的字段装配比较器，并使其返回0.

As a work around the problem, I tried to rig the comparator for the field which I don't want the comparator to compare and made it return 0.

assertThat(service.postComment(12,234,comment)).usingComparatorForFields((a,b)->0,"startDate").isEqualToComparingFieldByFieldRecursively(commentReturned);

但是，我仍然遇到这个异常.

But, still I get this exception.

Path to difference:  <startDate>
- expected: <null>
- actual  : <2017-04-12 18:28:06.766>

作为旁注-我不想比较startDate，因为它使用旧版java.util.Date来检索当前日期，而旧版java.util.Date也比较毫秒.

As a sidenote - I don't want to compare startDate because it retrieves current date using legacy java.util.Date which compares milli seconds too.

usingComparatorForFields的工作方式.我什至用isEqualToComparingFieldByField而不是isEqualToComparingFieldByFieldRecursively尝试了它，错误仍然存​​在(在同一情况下.对于需要递归比较的情况，此操作将失败.)

How does it usingComparatorForFields work. I even tried it using isEqualToComparingFieldByField instead of isEqualToComparingFieldByFieldRecursively and the error persists (in the same case. This one fails for cases where recursive comparison is required.)

推荐答案

从我看来，这似乎是一个错误，您正在使用什么版本的AssertJ?

This looks like a bug from what I see, what version of AssertJ are you using ?

您可以通过简单的测试在 assertj-core 中创建问题吗?情况下重现错误?

Can you create an issue in assertj-core with a simple test case reproducing the error ?
