As a part of the End to End REST Assured Tutorial, in this post, we will learn to compare the portion of JSON arrays and Objects using the JSONassert library. For more complex queries, and especially when your JSON parsing is part of a larger application, I recommend data binding. For this we started experimenting with ZJSONPATCH. Overall, I think the intent of this code is obscured by the Gson API being rather verbose. Does a summoned creature play immediately after being summoned by a ready action?
