Property with Json as a string

[OskarKlintrot]

I have this DTO:

class SimpleDtoWithJson
{
    public int Id { get; set; }
    public string Json { get; set; }
}

.Json will (should) always be json. Should I verify like this:

await Verify(dto).IgnoreMember<SimpleDtoWithJson>(x => x.Json);
await VerifyJson(dto.Json).UseFileName("unique");

or

await Verify(dto);

or is there a third alternative where I can specify that SimpleDtoWithJson.Json should be treated as json?

how about this

    [ModuleInitializer]
    public static void ModuleInitializer() =>
        VerifierSettings.MemberConverter<SimpleDtoWithJson, string>(
            target => target.Json,
            (target, value) => JToken.Parse(target.Json).ToString(Formatting.Indented));

    [Fact]
    public Task WithConverterAndMemberConverter() =>
        Verify(
            new SimpleDtoWithJson
            {
                Id = 10,
                Json = "{firstName: 'John'}"
            });

Thanks! I assume then that VerifyJson "only" verifies that the string is valid json? Apart from what Verify does.

VerifyJson performs the following actions

• Convert to JToken (if necessary).
• Apply ignore member by name for keys.
• PrettyPrint the resulting text.

Just in case anyone wonder how to do it with STJ instead of Newtonsoft:

VerifierSettings.MemberConverter<SimpleDtoWithJson, string>(
    target => target.Event,
    (target, _) => JsonSerializer.Serialize(
        JsonNode.Parse(target.Json) ?? throw new UnreachableException("SimpleDtoWithJson.Json should never parse to null."),
        new JsonSerializerOptions
        {
            Encoder = JavaScriptEncoder.UnsafeRelaxedJsonEscaping,
            WriteIndented = true
        }));
