Assert object equivalence by value-CodePudding

I'm sure i'm missing the obvious...

Say we have:

public class MyObject
{
    public string SomeProp { get; set; }
    public int AnotherProp { get; set; }
}

[Fact]
public void SomeTest()
{
    var a = new MyObject { SomeProp = "hello", AnotherProp = 9 };
    var b = new MyObject { SomeProp = "hello" };
    var c = new MyObject { AnotherProp = 9 };
    var d = new MyObject { SomeProp = "hello", AnotherProp = 9 };
}

What is the correct assertion to check that all of the properties match (e.g. a and b would return true, but all other combinations would return false?

At the moment, i'm doing equivalency checks, but have to do it in both directions? e.g.

    a.Should().BeEquivalentTo(b);
    b.Should().BeEquivalentTo(a);

Forgive me if this is clearly defined in the docs... I can't find it :/

CodePudding user response：

You can do something like

public class MyObject
{
    public string SomeProp { get; set; }
    public int AnotherProp { get; set; }

    public override bool Equals(object obj)
    {
        var other = obj as MyObject;

        if (other == null)
            return false;

        return other.SomeProp == SomeProp &&
               other.AnotherProp == AnotherProp;
    }
}

and then just do

Assert.True(a.Equals(d));

I do not know if there is any other way of doing this.

CodePudding user response：

Check the fluent assertions documentation here. It recommends implementing IComparable interface for what you need.

Also, if you check this:

a.Should().BeEquivalentTo(b);

You wouldnt/shouldnt check the oposite direction:

    b.Should().BeEquivalentTo(a);

Cause thats the same!
