C#用于ICloneable的测试用例

Question

如何在编写测试用例时获得object ICloneable.Clone()方法的覆盖率。

 #region ICloneable Members

    object ICloneable.Clone()
    {
        return this.Clone();
    }

    public new Blue Clone()
    {
        Blue _temp = (Blue)this.MemberwiseClone();
        _temp.Node = Node.Clone();

        return _temp;
    }

    #endregion

当前的覆盖范围如下

Answer 1

虽然这些可以是单独的情况，但下面是一个真正简化的测试/覆盖显示代码的示例。

//Arrange
Blue expected = new(); //populate as needed

//Act
Blue a = expected.Clone();
Blue b = (Blue)((ICloneable)expected).Clone();

//Assert - using FluentAsertions - cases should be self explanatory 
a.Should().BeEquivalentTo(b); 
a.Should().BeEquivalentTo(expected);
b.Should().BeEquivalentTo(expected);
