Primjeri sa REST-osiguranjem: GET, POST, PUT, PATCH, DELETE

Ovaj post objašnjava kako poslati API HTTP zahtjeve pomoću REST-ovjerene knjižnice. Primjeri obuhvaćaju GET, POST, PUT, PATCH i DELETE zahtjevi.

Zahtjevi za HTTP API koji imaju REST-garanciju

GET Zahtjev

HTTP GET zahtjev koristi se za dohvaćanje resursa s poslužitelja.

Sljedeći primjer koristi get() metoda iz REST-ovjerene knjižnice.

Primjer:

import io.restassured.RestAssured; import io.restassured.http.ContentType; import io.restassured.response.Response; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.BeforeAll; import org.junit.jupiter.api.Test; import static io.restassured.RestAssured.given; public class RestAssuredRequests {
@BeforeAll
public static void setup() {
RestAssured.baseURI = 'https://jsonplaceholder.typicode.com';
}
@Test
public void getRequest() {
Response response = given()


.contentType(ContentType.JSON)


.when()


.get('/posts')


.then()


.extract().response();

Assertions.assertEquals(200, response.statusCode());
Assertions.assertEquals('qui est esse', response.jsonPath().getString('title[1]'));
} }

DOBITI zahtjev s parametarima upita

Da bismo poslali parametre upita zajedno s GET zahtjevom, koristimo queryParam metoda:

import io.restassured.RestAssured; import io.restassured.http.ContentType; import io.restassured.response.Response; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.BeforeAll; import org.junit.jupiter.api.Test; import static io.restassured.RestAssured.given; public class RestAssuredRequests {
@BeforeAll
public static void setup() {
RestAssured.baseURI = 'https://jsonplaceholder.typicode.com';
}
@Test
public void getRequestWithQueryParam() {
Response response = given()


.contentType(ContentType.JSON)


.param('postId', '2')


.when()


.get('/comments')


.then()


.extract().response();

Assertions.assertEquals(200, response.statusCode());
Assertions.assertEquals('Meghan_Littel@rene.us', response.jsonPath().getString('email[3]'));
} }

POST zahtjev

HTTP POST zahtjev koristi se za objavljivanje podataka ili stvaranje resursa na poslužitelju.



Da bismo poslali POST zahtjev u REST-assured, koristimo post() metoda:

import io.restassured.RestAssured; import io.restassured.response.Response; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.BeforeAll; import org.junit.jupiter.api.Test; import static io.restassured.RestAssured.given; public class RestAssuredRequests {
private static String requestBody = '{ ' +

' 'title': 'foo', ' +

' 'body': 'bar', ' +

' 'userId': '1' }';
@BeforeAll
public static void setup() {
RestAssured.baseURI = 'https://jsonplaceholder.typicode.com';
}
@Test
public void postRequest() {
Response response = given()


.header('Content-type', 'application/json')


.and()


.body(requestBody)


.when()


.post('/posts')


.then()


.extract().response();

Assertions.assertEquals(201, response.statusCode());
Assertions.assertEquals('foo', response.jsonPath().getString('title'));
Assertions.assertEquals('bar', response.jsonPath().getString('body'));
Assertions.assertEquals('1', response.jsonPath().getString('userId'));
Assertions.assertEquals('101', response.jsonPath().getString('id'));
} }

PUT zahtjev

Zahtjev PUT ažurira resurs, ali zahtijeva potpunu nosivost JSON-a.

Da bismo poslali zahtjev za PUT u REST-assured, koristimo put() metoda:

import io.restassured.RestAssured; import io.restassured.response.Response; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.BeforeAll; import org.junit.jupiter.api.Test; import static io.restassured.RestAssured.given; public class RestAssuredRequests {
private static String requestBody = '{ ' +

' 'title': 'foo', ' +

' 'body': 'baz', ' +

' 'userId': '1', ' +

' 'id': '1' }';
@BeforeAll
public static void setup() {
RestAssured.baseURI = 'https://jsonplaceholder.typicode.com';
}
@Test
public void putRequest() {
Response response = given()


.header('Content-type', 'application/json')


.and()


.body(requestBody)


.when()


.put('/posts/1')


.then()


.extract().response();

Assertions.assertEquals(200, response.statusCode());
Assertions.assertEquals('foo', response.jsonPath().getString('title'));
Assertions.assertEquals('baz', response.jsonPath().getString('body'));
Assertions.assertEquals('1', response.jsonPath().getString('userId'));
Assertions.assertEquals('1', response.jsonPath().getString('id'));
} }

Zahtjev za PATCH

Zahtjev PATCH ažurira resurs, ali zahtijeva samo polja koja se ažuriraju u korisnom opterećenju:

import io.restassured.RestAssured; import io.restassured.response.Response; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.BeforeAll; import org.junit.jupiter.api.Test; import static io.restassured.RestAssured.given; public class RestAssuredRequests {
private static String requestBody = '{ ' +

' 'title': 'bax' }';
@BeforeAll
public static void setup() {
RestAssured.baseURI = 'https://jsonplaceholder.typicode.com';
}
@Test
public void patchRequest() {
Response response = given()


.header('Content-type', 'application/json')


.and()


.body(requestBody)


.when()


.patch('/posts/1')


.then()


.extract().response();

Assertions.assertEquals(200, response.statusCode());
Assertions.assertEquals('bax', response.jsonPath().getString('title'));
Assertions.assertEquals('1', response.jsonPath().getString('userId'));
Assertions.assertEquals('1', response.jsonPath().getString('id'));
} }

IZBRIŠI zahtjev

Zahtjev DELETE koristi se za brisanje resursa s poslužitelja.

Da bismo poslali zahtjev za IZBRIŠI u REST-assured, koristimo delete() metoda:

import io.restassured.RestAssured; import io.restassured.response.Response; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.BeforeAll; import org.junit.jupiter.api.Test; import static io.restassured.RestAssured.given; public class RestAssuredRequests {
@BeforeAll
public static void setup() {
RestAssured.baseURI = 'https://jsonplaceholder.typicode.com';
}
@Test
public void deleteRequest() {
Response response = given()


.header('Content-type', 'application/json')


.when()


.delete('/posts/1')


.then()


.extract().response();

Assertions.assertEquals(200, response.statusCode());
} }
