RestAssured: How to check the length of json array response?
提问by Héctor
I have an endpoint that returns a JSON like:
我有一个返回 JSON 的端点，如：
[
{"id" : 4, "name" : "Name4"},
{"id" : 5, "name" : "Name5"}
]
and a DTO class:
和一个 DTO 类：
public class FooDto {
public int id;
public String name;
}
Now, I'm testing the length of the returned json array this way:
现在，我以这种方式测试返回的 json 数组的长度：
@Test
public void test() {
FooDto[] foos = RestAssured.get("/foos").as(FooDto[].class);
assertThat(foos.length, is(2));
}
But, is there any way to do it without cast to FooDto array? Something like this:
但是，有没有什么办法可以在不强制转换为 FooDto 数组的情况下做到这一点？像这样的东西：
@Test
public void test() {
RestAssured.get("/foos").then().assertThat()
.length(2);
}

Solved! I have solved it this way:
解决了！我是这样解决的：
@Test
public void test() {
RestAssured.get("/foos").then().assertThat()
.body("size()", is(2));
}

There are ways. I solved with the below
有办法。我用下面的方法解决了
@Test
public void test() {
ValidatableResponse response = given().when().get("/foos").then();
response.statusCode(200);
assertThat(response.extract().jsonPath().getList("$").size(), equalTo(2));
}
using restassured 3.0.0
使用放心 3.0.0

I solved similar task wit GPath.
我用 GPath 解决了类似的任务。
Response response = requestSpec
.when()
.get("/new_lesson")
.then()
.spec(responseSpec).extract().response();
Now I can extract response body as String and use built-in GPath capabilities
现在我可以将响应正文提取为字符串并使用内置的 GPath 功能
String responseBodyString = response.getBody().asString();
assertThat(from(responseBodyString).getList("$").size()).isEqualTo(YOUR_EXPECTED_SIZE_VALUE);
assertThat(from(responseBodyString).getList("findAll { it.name == 'Name4' }").size()).isEqualTo(YOUR_EXPECTED_SUB_SIZE_VALUE);

[
{"id" : 4, "name" : "Name4"},
{"id" : 5, "name" : "Name5"}
]
It was really unlucky example. Here you have matrix [2,2].
这真是个倒霉的例子。这里有矩阵 [2,2]。
If you create something like this:
如果你创建这样的东西：
[
{"id" : 4, "name" : "Name4"},
{"id" : 5, "name" : "Name5"},
{"id" : 6, "name" : "Name6"}
]
Now you still get passed test:
现在你仍然通过了测试：
@Test
public void test() {
RestAssured.get("/foos").then().assertThat()
.body("size()", is(2));
}
Consider about whether it was intentional.
body("size()",is(2));Have checking length of one node instead of number of records in response.
考虑是否是故意的。
body("size()",is(2));检查一个节点的长度而不是响应的记录数。

You can simply call size()in your body path:
你可以简单地调用size()你的身体路径：
Like:
喜欢：
given()
.accept(ContentType.JSON)
.contentType(ContentType.JSON)
.auth().principal(createPrincipal())
.when()
.get("/api/foo")
.then()
.statusCode(OK.value())
.body("bar.size()", is(10))
.body("dar.size()", is(10));
回答by roy
This is what you need to do in order to get size.
这是您需要做的才能获得尺寸。
Response response =
given()
.header("Accept","application/json")
.when()
.get("/api/nameofresource")
.then()
.extract()
.response();
once you have the response, you can do the following to get the size.
获得响应后，您可以执行以下操作来获取大小。
int size = response.jsonPath().getList("id").size();
int size = response.jsonPath().getList("id").size();
hope this helps. :)
希望这可以帮助。:)
