Rest Assured¶

REST Assured is used to test REST services in java. See some examples here and Baeldung post

Test a GET

import io.restassured.http.ContentType;
import io.restassured.response.Response;
import static io.restassured.RestAssured.when;
@Test public void
lotto_resource_returns_200_with_expected_id_and_winners() {

    when().
            get("/lotto/{id}", 5).
    then().
            statusCode(200).
            body("lotto.lottoId", equalTo(5),
                 "lotto.winners.winnerId", hasItems(23, 54));

}

Other examples

InventoryResourceIT:

public void shouldGetOneInventory(){
        Response r = given().headers("Content-Type", ContentType.JSON, "Accept", ContentType.JSON)
        .when()
        .get("/inventory/Store-1/Item-1")
        .then()
        .statusCode(200)
        .contentType(ContentType.JSON)
        .extract()
        .response();

        System.out.println(r.jsonPath());
    }

Test a POST

import static io.restassured.RestAssured.given;

given().pathParam("numberRecords", 3)
          .when().post("http://localhost:8080/start/{numberRecords}")
          .then()
             .statusCode(200)
             .body(is("started"));

Another POST with taking the response body to a bean

import io.restassured.http.ContentType;
import io.restassured.response.Response;
import static io.restassured.RestAssured.with;

ClusterBasicInfo clusterInfo = new ClusterBasicInfo();
        clusterInfo.name = "localKafka";
        clusterInfo.adminURL = kafkaContainerForTest.getBootstrapServers();
        clusterInfo.bootstrapURL = clusterInfo.adminURL;
        Response resp = with().headers("Content-Type", ContentType.JSON, "Accept", ContentType.JSON)
          .body(clusterInfo)
          .when().post(basicURL)
          .then()
             .statusCode(200)
             .contentType(ContentType.JSON)
        .extract()
        .response();

        ClusterDetail updateDetails = resp.body().as(ClusterDetail.class);

And array of beans:

Response rep = given()
          .headers("Content-Type", ContentType.JSON, "Accept", ContentType.JSON)
          .when().get(basicURL)
          .then()
             .statusCode(200)
             .contentType(ContentType.JSON)
            .extract()
            .response();
            System.out.println(rep.jsonPath().prettyPrint());
            OrderDTO[] orders = rep.body().as(OrderDTO[].class);
            Assertions.assertTrue(orders.length >= 2);
