C# 如何为NSSubstitute.Received呼叫指定失败消息？

在NSubstitute中，是否可以指定在接收失败时应抛出的消息？如下所示：

[Test]
public void Should_execute_command()
{
    var command = Substitute.For<ICommand>();
    var something = new SomethingThatNeedsACommand(command);

    something.DoSomething();

    command.Received()
        .Execute()
        .Because("We should have executed the command that was passed in");
}

---

然后，您将在测试运行程序中获得该消息作为测试失败消息的一部分。这有助于使测试故障更易于读取/诊断。NSubstitute中是否有类似的内容？

无法更改您在

ReceivedCallException

中收到的消息；它直接从

NSubstitute.Core.receivedcallsexceptionRower

Throw

方法中的硬编码字符串构建：

public void Throw(ICallSpecification callSpecification, IEnumerable<ICall> matchingCalls, IEnumerable<ICall> nonMatchingCalls, Quantity requiredQuantity)
{
    StringBuilder stringBuilder = new StringBuilder();
    stringBuilder.AppendLine(string.Format("Expected to receive {0} matching:\n\t{1}", requiredQuantity.Describe("call", "calls"), callSpecification));
    this.AppendMatchingCalls(callSpecification, matchingCalls, stringBuilder);
    if (requiredQuantity.RequiresMoreThan<ICall>(matchingCalls))
    {
        this.AppendNonMatchingCalls(callSpecification, nonMatchingCalls, stringBuilder);
    }
    throw new ReceivedCallsException(stringBuilder.ToString());
}

public void Throw（ICallSpecification callSpecification、IEnumerable matchingCalls、IEnumerable nonMatchingCalls、Quantity required Quantity）
{
StringBuilder StringBuilder=新的StringBuilder（）；
stringBuilder.AppendLine（string.Format（“预期接收{0}匹配：\n\t{1}”，requiredQuantity.Descripte（“调用”，“调用”），调用规范））；
此.AppendMatchingCalls（callSpecification、matchingCalls、stringBuilder）；
if（requiredQuantity.requiresMore（匹配调用））
{
此.AppendNonMatchingCalls（调用规范、nonMatchingCalls、stringBuilder）；
}
抛出新的ReceivedCallsException（stringBuilder.ToString（））；
}

除非您已经准备好深入NSubstitute代码，否则目前最好的办法是捕获

ReceivedCallsException

并抛出您自己的消息

public void Throw(ICallSpecification callSpecification, IEnumerable<ICall> matchingCalls, IEnumerable<ICall> nonMatchingCalls, Quantity requiredQuantity)
{
    StringBuilder stringBuilder = new StringBuilder();
    stringBuilder.AppendLine(string.Format("Expected to receive {0} matching:\n\t{1}", requiredQuantity.Describe("call", "calls"), callSpecification));
    this.AppendMatchingCalls(callSpecification, matchingCalls, stringBuilder);
    if (requiredQuantity.RequiresMoreThan<ICall>(matchingCalls))
    {
        this.AppendNonMatchingCalls(callSpecification, nonMatchingCalls, stringBuilder);
    }
    throw new ReceivedCallsException(stringBuilder.ToString());
}
