NUnit的嵌套收藏比较 [英] NUnit Nested Collection Comparison

问题描述

有没有类似CollectionAssert.AreEquivalent（）与嵌套收藏作品的东西吗？

Is there something similar to CollectionAssert.AreEquivalent() that works with nested collections?

下面的代码...

CollectionAssert.AreEquivalent ( 
    new Dictionary<int, Dictionary<int, string>>
    {
        { 1, new Dictionary < int, string > { { 10, "foo" }, { 11, "bar" }, { 12, "spam" } } },
        { 2, new Dictionary < int, string > { { 20, "eggs" }, { 21, "eels" } } },
        { 3, new Dictionary < int, string > { { 30, "hovercraft" } } }
    },
    new Dictionary<int, Dictionary<int, string>>
    {
        { 1, new Dictionary < int, string > { { 10, "foo" }, { 11, "bar" }, { 12, "spam" } } },
        { 2, new Dictionary < int, string > { { 20, "eggs" }, { 21, "eels" } } },
        { 3, new Dictionary < int, string > { { 30, "hovercraft" } } }
    } );

引发此异常...

throws this exception...

Expected: equivalent to
    < [1, System.Collections.Generic.Dictionary`2[System.Int32,System.String]],
    [2, System.Collections.Generic.Dictionary`2[System.Int32,System.String]],
    [3, System.Collections.Generic.Dictionary`2[System.Int32,System.String]] >
But was:
    < [1, System.Collections.Generic.Dictionary`2[System.Int32,System.String]],
    [2, System.Collections.Generic.Dictionary`2[System.Int32,System.String]],
    [3, System.Collections.Generic.Dictionary`2[System.Int32,System.String]] >

以下断言通行证：

The following assert passes:

CollectionAssert.AreEquivalent (
    new Dictionary < int, string > { { 10, "foo" }, { 11, "bar" }, { 12, "spam" } },
    new Dictionary < int, string > { { 10, "foo" }, { 11, "bar" }, { 12, "spam" } } );

如果我更改了预期的收集，断言投用两个集合的全部内容异常在消息：

If I make changes to the expected collection, the assert throws an exception with the entire content of both collections in the message:

Expected: equivalent to < [10, foo], [11, bar], [12, spam] >
But was:  < [10, foo], [11, bar], [12, eggs] >

我使用NUnit 2.4.7.0。

I'm using NUnit 2.4.7.0.

推荐答案

这是老问题，但有人刚刚发布一个链接到它的NUnit，讨论...

An old question, but somebody just posted a link to it on nunit-discuss...

的失败因为NUnit的版本使用不支持两个字典之间的平等的比较和对象比较有所回落。最近的版本将不会有这个问题。

The failure is because the version of NUnit used did not support equality comparisons between two dictionaries and fell back on object comparison. Recent releases will not have this problem.
