Perl需要比较两个数据结构和返回差异 [英] Perl Need to Compare Two Data Structures and Return Differences

问题描述

我有两个数据结构，混合了散列和数组。我如何比较两个数据结构并返回他们的差异，像perl的Test :: Harness模块​​，但我不想实际运行单元测试。 ...或者有没有一个方法来调试Test ::线束，而不实际运行单元测试？

I have two data structures with a mix of hashes and arrays. How can I compare the two data structures and return their differences, something like perl's Test::Harness module, but I don't want to actually run a unit test. ...or is there a way to tun Test::Harness without actually running a unit test?

推荐答案

Perl Monks 说， Test :: Deep ， Data :: Compare 和 Data :: Match 是您的朋友。这些包似乎并不适合产生详细的差异，但你可能能够在回调中跟踪精确的差异。

Perl Monks says that Test::Deep, Data::Compare, and Data::Match are your friends. Those packages don't seem to be geared towards producing detailed diffs but you might be able to hack in a callback to keep track of the precise differences.
