Rest Assured verifying JSON list of key/value pairs

Question

Using Rest Assured (io.restassured) in Java and have the following JSON response format

{
"products": [
    {
      "name": "toy1",
      "price": 99
    },
    {
      "name": "toy2",
      "price": 88
    },
    {
      "name": "toy3",
      "price": 99
    }
  ]
}

I'm trying to find if a specific product exist given it's name and price.

So the following result (or assert) is expected

name	price	isExist
toy1	99	true
toy2	99	false
toy2	88	true
sometoy	99	false

I tried:

• converting the JSON into a list of maps, but the overall solution was really messy
• found a package that would be convenient and solve my problem, but there's restrictions preventing me from using it
• considered flattening it, but that won't work since there would be key clashes

Answer 1

There are 2 solutions

1. Create a POJO class for the sample JSON (leverage online json to pojo converters - https://json2csharp.com/code-converters/json-to-pojo)
2. If you don't want to create extra POJO class, you can go ahead with io.restassured.path.json.JsonPath.

Here's an example of 2nd one.

public static void main(String[] args) {
    // Example JSON response
    String jsonResponse = "{ \"products\": ["
            + "{ \"name\": \"toy1\", \"price\": 99 },"
            + "{ \"name\": \"toy2\", \"price\": 88 },"
            + "{ \"name\": \"toy3\", \"price\": 99 }"
            + "] }";

    // Parse JSON response
    JsonPath jsonPath = new JsonPath(jsonResponse);

    // Check for product existence
    System.out.println(doesProductExist("toy1", 99, jsonPath)); // true
    System.out.println(doesProductExist("toy2", 99, jsonPath)); // false
    System.out.println(doesProductExist("toy2", 88, jsonPath)); // true
    System.out.println(doesProductExist("sometoy", 99, jsonPath)); // false
}

public static boolean doesProductExist(String name, int price, JsonPath jsonPath) {
    List<Map<String, Object>> products = jsonPath.getList("products");
    return products.stream()
        .anyMatch(product -> name.equals(product.get("name")) && price == (int) product.get("price"));
}
