c# - CollectionAssert of an nested List -

how assert nested list too, without 'unnesting' it?

        expected.add(new customer{                 edition = "cust",                 rarity = "r",                 id = 1001,                 name = "john doe",                 types = new list<type_>{                     new type_{                         id = 1,                         name = "abc"                     }                 }, 

here assert:

collectionassert.areequal(expected, actual); 

that exclude nested list.

something worked me:

• generate object hash (such md5) includes content of list, quite rigid approach , seldom useful
• just write second assert in test inner list. more conventional approach (my favourite)
• write new test assert inner list. more tdd-purist approach

edit, here example of conventional approach:

var expected = new list<type_>{                     new type_{                         id = 1,                         name = "abc"                     }; collectionassert.areequal(expected, actual.types);
