Problem with checking values of JSON array using Rest Assured

问题

我正在尝试使用Rest-Assured为我的应用程序添加一些测试，但我无法弄清楚如何断言一些嵌套值。错误消息如下：

期望：（包含“json”的集合）
实际：[[json，spring，gulp，path等...]]

以下是代码：

  1.  when().
  2.        get("/api/personsByID/{id}/{count}", 262, 2).
  3.        then().
  4.        statusCode(200).
  5.        body("personDependencies.name", hasItems("json"));

以下是由rest控制器返回的JSON文件：

  1. [
  2.     {
  3.         "id": 346,
  4.         "verified": true,
  5.         "displayName": "eda656a2c3cb59ae840e40a28ba4ab50bfb9de0185abcb901c6af6dc59d6668f",
  6.         "emails": [
  7.             {
  8.                 "email": "16a23f2e5477df0bbcad718c3abc235b2cb8a1b6648d14f58d42a7be13df2b6e"
  9.             }
  10.         ],
  11.         "personDependencies": [
  12.             {
  13.                 "name": "json"
  14.             },
  15.             {
  16.                 "name": "spring"
  17.             },
  18.             {
  19.                 "name": "gulp"
  20.             },
  21.             {
  22.                 "name": "path"
  23.             },
  24.             ...
  25.             // 其他项
  26.             ...
  27.             {
  28.                 "name": "javax.servlet"
  29.             }
  30.         ],
  31.         "countries": [],
  32.         "member_of": [],
  33.         "projects": [],
  34.         ...
  35.         // 其他项
  36.         ...
  37.         "distance": 0.6028837702084446
  38.     }
  39. ]

我不知道如何进行适当的断言，任何帮助都将是很好的。谢谢！

I'm trying to add some tests with Rest-Assured to my application, but I can't figure out how to assert some nested values. The error message is :
>Expected: (a collection containing "json")
Actual: [[json, spring, gulp, path etc...]]

Here is the code :

  1.  when().
  2.        get("/api/personsByID/{id}/{count}", 262, 2).
  3.        then().
  4.        statusCode(200).
  5.        body("personDependencies.name", hasItems("json"));

And here is the JSON file that is returned by rest controller:

  1. [
  2.     {
  3.         "id": 346,
  4.         "verified": true,

  9.             }
  10.         ],
  11.         "personDependencies": [

I have no idea how to make proper assertions, any help would be great. Thanks!

如果我理解您的问题正确，您需要检查特定值是否存在于返回给定ID的列表中。

以下内容适用于您：

  1. given().when().get().then().body("find {it.id == 346}.personDependencies.name", hasItems("json", "jackson"));
英文:

If I am reading your question right you need to check if a certain values are present in a list that is returned for a particular ID

The below should work for you

  1. given().when().get().then().body("find {it.id == 346}.personDependencies.name", hasItems("json", "jackson"));

第一个问题是你不需要使用hasItems来检查项目的存在，应该使用hasItem。

  1. when().
  2.        get("/api/personsByID/{id}/{count}", 262, 2).
  3.        then().
  4.        statusCode(200).
  5.        body("personDependencies.name", hasItem("json"));

然后，如果在测试失败时需要向断言添加更多消息，你可以这样做：

  1. when().
  2.         get("/api/personsByID/{id}/{count}", 262, 2).
  3.         then().
  4.         statusCode(200).
  5.         body("personDependencies.name",  describedAs("数组不包含所提供的项", hasItem("json")));

在你的情况下，你可以这样验证：

  1. when().
  2.        get("/api/personsByID/{id}/{count}", 262, 2).
  3.        then().
  4.        statusCode(200).
  5.        body("personDependencies[*].name", hasItem("json"));
英文:

The first problem you don't need to check the presence of an item with hasItems, you should use hasItem

  1. when().
  2.        get("/api/personsByID/{id}/{count}", 262, 2).
  3.        then().
  4.        statusCode(200).
  5.        body("personDependencies.name", hasItem("json"));

Then if you need to add more message to the assertion when the test fails you can do such way:

  1.  when().
  2.         get("/api/personsByID/{id}/{count}", 262, 2).
  3.         then().
  4.         statusCode(200).
  5.         body("personDependencies.name",  describedAs("Array not containing the provided item",hasItem("json")));

In your case you can validate such a way:

  1. when().
  2.        get("/api/personsByID/{id}/{count}", 262, 2).
  3.        then().
  4.        statusCode(200).
  5.        body("personDependencies[*].name", hasItem("json"));

Wilfred Clement的回答非常好。只想再添加一个例子以更好地理解概念和语法。
如果您必须在某个不在JSON的'root'级别上的数组中进行类似的搜索，请使用以下语法：

  1. .body("problems.find {it.property == 'boardUrl'}.details", is("size must be between 1 and 256"))

此路径适用于以下JSON结构：

  1. {
  2. "title": "Bad Request",
  3. "status": 400,
  4. "problems": [
  5.     {
  6.         "property": "tag",
  7.         "value": "too-big-tag-value",
  8.         "details": "size must be between 1 and 10"
  9.     },
  10.     {
  11.         "property": "name",
  12.         "value": "Very big name for testing purposes",
  13.         "details": "size must be between 1 and 20"
  14.     }
  15.   ]
  16. }
英文:

Wilfred Clement's answer is great. Just want to add 1 more example for better understanding concept and syntax.
Use next syntax if you have to make similar search in some array which is not on 'root' level of JSON:

  1. .body("problems.find {it.property == 'boardUrl'}.details", is("size must be between 1 and 256"))

This path is created for the JSON structure below:

  1. {
  2. "title": "Bad Request",
  3. "status": 400,
  4. "problems": [
  5.     {
  6.         "property": "tag",
  7.         "value": "too-big-tag-value",
  8.         "details": "size must be between 1 and 10"
  9.     },
  10.     {
  11.         "property": "name",
  12.         "value": "Very big name for testing purposes",
  13.         "details": "size must be between 1 and 20"
  14.     }
  15.   ]
  16. }
