C# FluentAssertions因子输出重复配置

我有如下的单元测试代码：

// version3 should be a copy of version2 with some differences
version3.Data.ShouldBeEquivalentTo(version2,
  option => option
    .Excluding(x => x.Id)
    .Excluding(x => x.Status)
    .Excluding(x => x.Stale)
    .Excluding(x => x.Body)
    .Excluding(x => x.CreatedBy)
    .Excluding(x => x.UpdatedBy),
  "because version3 is version2 updated");

// version3 should be a copy of version2 with some differences
version3.Data.ShouldBeEquivalentTo(version2,
  option => baseOption,
  "because version3 is version2 updated");

然后又

// version4 should be a copy of version3 with some differences
version4.Data.ShouldBeEquivalentTo(version3,
  option => option
    .Excluding(x => x.Id)
    .Excluding(x => x.Status)
    .Excluding(x => x.Stale)
    .Excluding(x => x.Body)
    .Excluding(x => x.CreatedBy)
    .Excluding(x => x.UpdatedBy),
  "because version4 is version3 updated");

如何将

选项

计算出来

我想做这样的事情：

// version3 should be a copy of version2 with some differences
version3.Data.ShouldBeEquivalentTo(version2,
  option => option
    .Excluding(x => x.Id)
    .Excluding(x => x.Status)
    .Excluding(x => x.Stale)
    .Excluding(x => x.Body)
    .Excluding(x => x.CreatedBy)
    .Excluding(x => x.UpdatedBy),
  "because version3 is version2 updated");

// version3 should be a copy of version2 with some differences
version3.Data.ShouldBeEquivalentTo(version2,
  option => baseOption,
  "because version3 is version2 updated");

甚至可能是这样：

// version3 should be a copy of version2 with some differences
version3.Data.ShouldBeEquivalentTo(version2,
  option => baseOption
    .Excluding(x => x.OtherProperty),
  "because version3 is version2 updated");

将选项委托外部声明为基础

Func<FluentAssertions.Equivalency.EquivalencyAssertionOptions<MyDataType>,
    FluentAssertions.Equivalency.EquivalencyAssertionOptions<MyDataType>>
    baseOption = option => option
        .Excluding(x => x.Id)
        .Excluding(x => x.Status);

对于需要构建在基础上的其他断言，您必须调用委托并附加其他选项

// version3 should be a copy of version2 with some differences
version3.Data.ShouldBeEquivalentTo(version2,
  option => baseOption(option)
    .Excluding(x => x.OtherProperty),
  "because version3 is version2 updated");

您应该注意，当前使用的语法在较新版本的框架中已被弃用

version3.Should().BeEquivalentTo(version2, baseOption, 
    "because version3 is version2 updated");

或者切换到v5，以便将测试对象与匿名类型进行比较，在匿名类型中，您只定义您关心的特定测试属性。

在方法调用外部声明委托，并根据需要附加到该委托。请提供一个示例。这个特性简化了很多测试用例。
