使用Rest Assured检查JSON数组的值时出现问题

Question

我正试图在我的应用程序中添加一些带有Rest Assured的测试，但我不知道如何断言一些嵌套值。错误消息为：

预期：(包含"json"的集合(实际：[[json，spring，gullow，path等]]

这是代码：

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

这是rest控制器返回的JSON文件：

我不知道如何做出正确的断言，任何帮助都会很好。谢谢

Answer 1

如果我读对了你的问题，你需要检查为特定ID 返回的列表中是否存在特定值

以下内容应该适用于

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

Answer 2

第一个问题是，你不需要用hasItems检查项目的存在，你应该使用hasItem

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

然后，如果您需要在测试失败时向断言添加更多消息，您可以这样做：

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

在您的情况下，您可以通过以下方式进行验证：

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

Answer 3

Wilfred Clement的回答很棒。我只想再添加一个例子，以便更好地理解概念和语法。如果您必须在某个不在JSON的"根"级别的数组中进行类似的搜索，请使用下一个语法：

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

此路径是为以下JSON结构创建的：

{
"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"
}
]
}
