我有一个看起来像这样的类:
public myArguments
{
public List<string> argNames {get; set;}
}
在我的测试中,我这样做:
var expectedArgNames = new List<string>();
expectedArgNames.Add("test");
_mockedClass.CheckArgs(Arg.Any<myArguments>()).Returns(1);
_realClass.CheckArgs();
_mockedClass.Received().CheckArgs(Arg.Is<myArguments>(x => x.argNames.Equals(expectedArgNames));
但测试失败并显示此错误消息:
NSubstitute.Exceptions.ReceivedCallsException : Expected to receive a call matching:
CheckArgs(myArguments)
Actually received no matching calls.
Received 1 non-matching call (non-matching arguments indicated with '*' characters):
CheckArgs(*myArguments*)
我猜这是因为 .Equals()
但我不确定如何解决它?
最佳答案
在您的测试中,您正在比较 myArguments
用List<string>
上课.
您应该比较 myArguments.argNames
与 List<string>
或实现 IEquatable<List<string>>
在myArguments
.
此外,当你比较List<T>
时, 你应该使用 SequenceEquals
而不是 Equals
.
第一个选项是:
_mockedClass.Received().CheckArgs(
Arg.Is<myArguments>(x => x.argNames.SequenceEqual(expectedArgNames)));
第二个是:
public class myArguments : IEquatable<List<string>>
{
public List<string> argNames { get; set; }
public bool Equals(List<string> other)
{
if (object.ReferenceEquals(argNames, other))
return true;
if (object.ReferenceEquals(argNames, null) || object.ReferenceEquals(other, null))
return false;
return argNames.SequenceEqual(other);
}
}
