NUnit：检查两个字典是否相同的 API

发布于 2024-08-19 11:30:56 字数 895 浏览 1 评论 0原文

给定两个字典，

var dictA = new Dictionary<string, classA>();
var dictB = new Dictionary<string, classA>();

如何检查这两个字典是否相同？ 这里的问题是我无法使用默认的classA.Equals来比较值对。相反，当且仅当字典中所有 classA 类型的对象必须满足我自己的自定义 IEqualityComparer 时，测试才会通过。

具体来说，我正在寻找类似

CollectionAssert.AreEquivalent(dictA, dictB, new ClassEqualityComparer());

ClassEqualityComparer 继承自 IEqualityComparer 的东西，或等效的东西。我不介意是否必须子类化 IEqualityComparer 的 NUnit 类型（例如 IResolveConstraint），但最重要的是 Assert > 方法必须类似于

Assertion(dictA, dictB, EqualityComparer)

或者更简单的东西；我不想使用 Assert.That，然后实现一种 IResolveConstraint 类型，该类型运行到页面中只是为了检查两个字典是否相同。

有什么想法吗？

原文

Given two dictionaries

var dictA = new Dictionary<string, classA>();
var dictB = new Dictionary<string, classA>();

How to check whether these two dictionaries are the same? The catch here is that I can't use the default classA.Equals for comparing the value pairs. Instead, the test will pass when and only when given that all the object of the classA type in the dictionaries must satisfy my own custom IEqualityComparer<ClassA>.

Specifically, I am looking at something like

CollectionAssert.AreEquivalent(dictA, dictB, new ClassEqualityComparer());

with ClassEqualityComparer inherits from IEqualityComparer<ClassA>, or equivalent. I don't mind if I have to subclass a NUnit type of IEqualityComparer ( such as IResolveConstraint), but the most important thing is that the Assert method must be something like

Assertion(dictA, dictB, EqualityComparer)

Or something even more simpler; I don't want to use Assert.That and then implement a type of IResolveConstraint that runs into pages just to check whether two dictionaries are the same.

Any idea?

所以我想你需要测试字典“B”包含与“A”相同的键，反之亦然，然后使用比较器来比较每个值：

Assert.IsTrue(dictA.Keys.All(k => dictB.ContainsKey(k));
Assert.IsTrue(dictB.Keys.All(k => dictA.ContainsKey(k));

var cmp = new ClassEqualityComparer();
Assert.IsTrue(dictA.Keys.All(k => cmp.Equals(dictA[k], dictB[k]));

这有效吗？

So I guess you'll need to test that dictionary "B" contains all the same keys as "A" and vice versa, and then use your comparer to compare each value:

Assert.IsTrue(dictA.Keys.All(k => dictB.ContainsKey(k));
Assert.IsTrue(dictB.Keys.All(k => dictA.ContainsKey(k));

var cmp = new ClassEqualityComparer();
Assert.IsTrue(dictA.Keys.All(k => cmp.Equals(dictA[k], dictB[k]));

Will that work?
