How to automate GET method and validate status code using Rest Assured?

Answer

Automate GET Method in Rest Assured

Basic GET and Status Code Validation

Java

import io.restassured.RestAssured;
import io.restassured.response.Response;
import static io.restassured.RestAssured.*;
import static org.testng.Assert.*;

public class ApiTest {

    @Test(description = "Verify status code for GET method")
    public static void verifyStatusCodeGET() {

        Response resp = given()
                            .when()
                            .get("https://reqres.in/api/users/2");

        assertEquals(resp.getStatusCode(), 200);
    }
}

Fluent Style (BDD Syntax)

Java

@Test
public void verifyGetStatusCode() {
    given()
        .when()
        .get("https://reqres.in/api/users/2")
        .then()
        .statusCode(200);
}

With Base URI Setup

Java

@BeforeClass
public void setup() {
    RestAssured.baseURI = "https://reqres.in";
}

@Test
public void getUser() {
    given()
        .when()
        .get("/api/users/2")
        .then()
        .statusCode(200)
        .log().all();
}

Key Methods

Method	Purpose
`given()`	Sets up request specification
`when()`	Triggers the HTTP action
`get(url)`	Sends GET request
`getStatusCode()`	Returns the HTTP status code
`.then().statusCode(200)`	BDD-style status assertion
