REST assured - compare two JSON objects

Question

Suppose the GET request returns me some JSON object:

{
 "a": 1, "b": 2, "c": 3, "date": "current_date"
}

And I have in my hand a similar object, which I'd like to check it's identical for the the keys "a", "b", "c" and ignore the "date" key.

How can I do that?

Answer 1

I have been using JsonUnit and it really helps

String json1 = "{\r\n" + "  \"a\": 1,\r\n" + "  \"b\": 2,\r\n" + "  \"c\": 3,\r\n"
            + " \"date\": \"30-07-2020\"\r\n" + "}";

String json2 = "{\r\n" + "  \"a\": 1,\r\n" + "  \"b\": 2,\r\n" + "  \"c\": 3,\r\n"
            + " \"date\": \"31-07-2020\"\r\n" + "}";

assertThatJson(json1).whenIgnoringPaths("date").isEqualTo(json2);

Static Import :

import static net.javacrumbs.jsonunit.assertj.JsonAssertions.assertThatJson;

Dependency :

    <dependency>
        <groupId>net.javacrumbs.json-unit</groupId>
        <artifactId>json-unit-assertj</artifactId>
        <version>2.18.1</version>
        <scope>test</scope>
    </dependency>

You will have to add json.org or Jackson 1.x or Jackson 2.x or Johnzon or Gson to the classpath as well

I use Jackson
