We need to convert the given JSON to JsonNode ( or ObjectNode or ArrayNode) first and then we can call the equals method on it. @RuiJarimba Of course deserializing as C# objects gives better error messages, but I didnot use this approach in all the places since it's a test project and we deal with variety of Json responses and the effort for creating class object for each one is pretty high and too much of overload. @user1496062 did you downvote my answer?
