What tools did you use for working with HTTP?

CURL: For testing APIs from the command line, debugging HTTP requests and responses.

Postman / Insomnia: For manual and automated API testing, creating and saving requests, working with collections, generating test scenarios.

Swagger UI / OpenAPI Specification: For understanding API structure, testing endpoints, generating client code.

Mitmproxy: For intercepting, modifying, and analyzing HTTP/HTTPS traffic between client and server.

Browser Developer Tools (Chrome DevTools, Firefox Developer Edition): For analyzing network requests, debugging frontend applications, studying headers and request/response bodies.

Requests (Python library): For writing automated tests and scripts that send HTTP requests.

# Using requests to send a GET request
import requests

def test_api_status():
    url = "https://example.com/api/status"
    response = requests.get(url)
    assert response.status_code == 200
    assert response.json() == {"status": "ok"}

JUnit / TestNG (using libraries for HTTP clients, e.g., RestAssured): For writing E2E and integration tests interacting with APIs.

// Example with RestAssured in Java
import io.restassured.RestAssured;
import org.junit.jupiter.api.Test;

public class ApiTest {

    @Test
    public void testGetUsers() {
        RestAssured.given()
            .when()
            .get("https://reqres.in/api/users?page=2")
            .then()
            .statusCode(200); // Check response status
    }
}
