If you use NUnit you may using this syntax and specify an IEqualityComparer specifically for the test:

[Test]
public void CompareObjectsTest()
{
    ClassType object1 = ...;
    ClassType object2 = ...;
    Assert.That( object1, Is.EqualTo( object2 ).Using( new MyComparer() ) );
}

private class MyComparer : IEqualityComparer
{
    public bool Equals( ClassType x, ClassType y )
    {
        return ....
    }

    public int GetHashCode( ClassType obj )
    {
        return obj.GetHashCode();
    }
}
