unit-testing - IEnumerables 的 `Assert.AreEqual` 和 `CollectionAssert.AreEqual` 之间的 Nunit 区别

Question

在Nunit中，有什么区别

Assert.AreEqual(IEnumerable<T>, IEnumerable<T>)

和

CollectionAssert.AreEqual(IEnumerable<T>, IEnumerable<T>)

?

Answer 1

没有超载Assert.AreEqual(IEnumerable<T>, IEnumerable<T>)，只有Assert.AreEqual(object, object)。至少对于nunit2.5.10，它们的实现是相同的：

集合断言.cs

public class CollectionAssert
{
    public static void AreEqual(IEnumerable expected, IEnumerable actual)
    {
      Assert.That((object) actual, (IResolveConstraint) new EqualConstraint((object) expected));
    }
}

断言.cs

public class Assert
{
    public static void AreEqual(object expected, object actual)
    {
      // EqualConstraint EqualTo(object expected)
      Assert.That(actual, (IResolveConstraint) Is.EqualTo(expected), (string) null, (object[]) null);
    }
}
