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：
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
body("personDependencies.name", hasItems("json"));
以下是由rest控制器返回的JSON文件：
[
{
"id": 346,
"verified": true,
"displayName": "eda656a2c3cb59ae840e40a28ba4ab50bfb9de0185abcb901c6af6dc59d6668f",
"emails": [
{
"email": "16a23f2e5477df0bbcad718c3abc235b2cb8a1b6648d14f58d42a7be13df2b6e"
}
],
"personDependencies": [
{
"name": "json"
},
{
"name": "spring"
},
{
"name": "gulp"
},
{
"name": "path"
},
...
// 其他项
...
{
"name": "javax.servlet"
}
],
"countries": [],
"member_of": [],
"projects": [],
...
// 其他项
...
"distance": 0.6028837702084446
}
]
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 :

Here is the code :
when().

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：
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
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。
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
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：
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
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：
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
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
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
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:
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
body("personDependencies.name", describedAs("Array not containing the provided item",hasItem("json")));
In your case you can validate such a way:
when().
get("/api/personsByID/{id}/{count}", 262, 2).
then().
statusCode(200).
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：
.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：
{
"title": "Bad Request",
"status": 400,
"problems": [
{
"property": "tag",
"value": "too-big-tag-value",
"details": "size must be between 1 and 10"
},
{
"property": "name",
"value": "Very big name for testing purposes",
"details": "size must be between 1 and 20"
}
]
}
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:
.body("problems.find {it.property == 'boardUrl'}.details", is("size must be between 1 and 256"))
This path is created for the JSON structure below:
{
"title": "Bad Request",
"status": 400,
"problems": [
{
"property": "tag",
"value": "too-big-tag-value",
"details": "size must be between 1 and 10"
},
{
"property": "name",
"value": "Very big name for testing purposes",
"details": "size must be between 1 and 20"
}
]
}
